Recycling Waste Water the Key to Water Security

February 22nd, 2018 Posted by Press Releases 0 thoughts on “Recycling Waste Water the Key to Water Security”

Witbank, 22 February 2018: Could it be that recycling the water we have is the key to water availability relief for the Cape region – as opposed to imposing increasingly stricter and potential unviable water usage restrictions as well as costly desalination? SewTreat have put forward another option – the biological treatment and recycling of waste water.

 

The Cape’s worst drought in a century has the region’s reservoirs and dams at record lows. The communities in the region are now at severe risk of running out of water altogether while the all-important agricultural sector has been plunged into crisis, affecting the local economy. With the latest ‘Day Zero’ restrictions set to be put into place allowing residents a mere 25 litres per day for personal use, the situation is now more dire than anyone could have predicted.

 

SewTreat spokesperson, Theunis Coetzer, says that these restrictions ultimately still result in water wastage. “We need to ask ourselves if whether we are restricting use to 25 litres per person per day destined to go down the drain and be gone forever. Not if we could recycle this back into clean, safe drinking water,” says Coetzer. “In the past the costs of the infrastructure required and the fact that we had cost effective water supply, prevented the technology to take root,  but modular plant designs using biological treatment methods are changing the game.”

 

Treating sewage water and waste water for re-use is by no means a new concept but previously the methods used and the infrastructure construction needed to implement water recycling have made it a wonderful ‘green’ dream that no one could financially realise. We have also had relatively cost effective water being supplied to us. In addition to this, Coetzer explains that there has been a stigma around drinking or re-using treated and recycled sewage water. “What businesses, schools and hospitals will start to realise is that recycling water by means of natural, eco-friendly, biological treatment methods is the best and most cost effective way to ensure water availability and security – and that it is now becoming a matter of life and death.”

 

While the concept was unthinkable in a South African setting two years ago, it has been successfully done in numerous countries around the world for years. In 2014, three years into California’s worst drought in over a century, the state’s Orange County Water District (OCWD), established a pioneering waste water treatment facility that recycles used water – or sewage – and returns it to the drinking supply. The plant’s production expanded from 259 to 370 million litres per day which is enough for 850,000 people.

 

Closer to home, Windhoek has been successfully treating waste water to drinking standards for the past 50 years. Most of the waste water produced by Windhoek’s 300 000 residents is sent to the Goreangab waste treatment plant – the first stop in the city’s pioneering water recycling system. The systems and technology have more than proven themselves – and far from being repulsed by the idea of drinking recycled sewage water, the residents have no complaints and are in fact proud of what they have achieved with the plant. Many call it Africa’s origin story for water reclamation and potable reclamation, and the plant gets thousands of visitors from around the world who are keen to see where this all started way back in 1968.

 

Businesses, organisations, residential estates, schools, retirement homes, retail spaces, farms and communities will likely be pursuing the installation of modular, biological waste water treatment plants in the year ahead because these systems can be implemented very quickly and at an affordable price. In fact the price comparison between re-cycling used and sewage water and desalination is staggering. The cost factor is based around the highly concentrated waste (brine) and high electrical energy requirements for desalination that make it more expensive in terms of Rand per litre for the final drinkable water.

 

SewTreat offers specialized, modular biological waste water treatment plant designs tailor-made for the South African and African market. Their approach is based on return activated sludge technology incorporating submersed aeration media. This enhanced bacterial action ensures a highly effective treatment process boasting a very low carbon footprint, minimal capital input and low maintenance requirements.

 

Their product offering includes modular Fibre Glass waste water treatment plants that can be installed either above or below ground for any operation from home use to medium sized business operations. Tailor-made for homeowners and lodges, they also offer DIY plants that are cost effective and easy to install. For larger business operations and firms within the industrial sectors, Sewtreat also offers Mega and Civil Constructed waste water treatment plants.

 

“It is 100% possible to recycle both sewage and waste water to the point that it is safe for drinking. We are facing a major water crisis of epic proportions and it is time to recognise this process for the major contribution that it can make to water security,” Cotzer concludes.

Famed SA Attraction Benefits from SewTreat’s Sustainable Sanitation Technology

November 2nd, 2017 Posted by Press Releases 0 thoughts on “Famed SA Attraction Benefits from SewTreat’s Sustainable Sanitation Technology”

Witbank, 17 October 2017: The environmental footprint of world renowned tourist attraction, the Bourke’s Luck Potholes in Mpumalanga, has been taken to new level thanks to SewTreat’s supply of a biological waste water treatment plant for the Mpumalanga Tourism & Parks Agency.

 

The existing septic tank system servicing the main reception and bathroom facilities at Bourke’s Luck Potholes has been replaced with sustainable sanitation technology thanks to SewTreat. “This technology will ensure that from now on, only clean, recycled effluent is discharged into the Blyde River thereby helping to conserve and preserve the precious ecosystem if the Blyde River system,” enthused Theunis Coetzer, spokesperson for SewTreat.

 

The Bourke’s Luck Potholes welcomes in excess of 1 million visitors annually – the majority of which are foreign tourists. According to Coetzer, the existing infrastructure was out-dated could not cope with the high volumes of effluent produced.  “The old septic system was discharging substandard effluent into the Blyde River causing secondary contamination and pollution of this pristine river system,” said Coetzer.

 

Through the appointed consulting engineers for the project, SewTreat was contracted by the Mpumalanga Tourism and Parks Agency to design, construct and install a complete waste water treatment plant for all effluent generated by the current sanitation facilities at the Bourke’s Luck Potholes site. The decision to appoint SewTreat was based on the ability of their products to treat waste water and sewage using environmentally friendly methods.

 

“Our motto is to treat nature with nature,” Coetzer explained. “All our plants make use of our proprietary strain of natural bacteria developed by our in-house team. The bacteria ensure that all waste is treated by a biological process resulting in a clean final effluent that is kinder to the environment.”

 

Biological wastewater treatment is an accepted practice used worldwide. The process involves confining naturally occurring bacteria at a very high concentration in the treatment process, whether it in plastic type, containerised type or civil constructed type treatment plants. From here this bacteria, together with some protozoa and other microbes (collectively referred to as activated sludge), are treated in an anaerobic and an aerobic process. They are then returned to the anaerobic phase to eliminate sludge accumulation and waste generation. Coetzer elaborated by saying: “In a nutshell, the bacteria digest all impurities and the wastewater is then cleansed. The treated wastewater or effluent can then be safely discharged to receiving waters – normally a river or the sea – or alternatively used for irrigation, flushing of toilets or general non-potable uses.”

 

After conducting a full assessment, SewTreat opted to supply a plastic, above ground type waste water treatment plant which would cope with the amount of waste to be processed daily, could be installed easily given the challenging access to the site and would be completed under a tight deadline and budget. SewTreat’s technology will now ensure that the Bourke’s Luck Potholes and the Blyde river system are kept pristine and unpolluted at a staggering rate of 7.5 million litres per year.

 

Coetzer concluded by saying: “We hope that by offering wastewater management products that are cost effective, easy to install, simple to maintain and provide a green waste solution; we can help all of our precious local tourism and conservation sites move towards a greener future. Preventing further damage to the environment requires a fundamental shift in how tourism operations conduct their business and manage resources. Changing how you treat your wastewater to a method that results in reusable effluent is a major step towards sustainability where the long term beneficiaries will be South Africa’s nature, wildlife and resources.”

The Easiest Way to Save Water Around the Home this Year

January 20th, 2017 Posted by Press Releases 0 thoughts on “The Easiest Way to Save Water Around the Home this Year”

Although choosing to go green in any part of your daily life is a noble effort, it might not always be feasible or simple to fit into your lifestyle. Theunis Coetzer, spokesman for local waste water treatment firm, SewTreat, provides a solution that will help you make water conservation an easy resolution to stick to this year.

“Few people likely make New Year’s resolutions about conserving water and this can be attributed to the fact that it is simply too difficult to achieve for a number of reasons,” Coetzer says.  “But, reducing water consumption is something we all must take very seriously now. Although the country has received some very welcome rainfall recently, we are not in the clear yet with regards to water shortages.”

Understandably, if you have a growing family it is difficult to cut back on the endless loads of laundry that need to be done or use of that of life saving dishwasher. Some might not want to give up those blissfully long showers after a tough day or might be concerned about the garden they have been nurturing for years and simply can’t bear to water less. With so many practical lifestyle factors to consider, how do you overcome the challenge of introducing water saving measures to your home? SewTreat has the answer – manage your home’s waste sustainably and create treated water that can be re-used.

SewTreat offers easy-to-install waste water treatment plants that offer homeowners a sensible and practical green feature to add to their home that will recycle 100% of previously discarded water. In addition to this, you could save up to 50% on your monthly water bill!

“Clean drinking water is purchased from a municipality. Around 80% of this water ends up being discharged into the municipal sewers which you are also being charged for by the municipality. So, in essence, homeowners pay twice for the same water,” Coetzer explains. “By installing a wastewater treatment system for your home, the discard cost is eliminated and all the water that is treated can be reused for irrigation, washing your car and other non-potable uses around the house.”

SewTreat offers two types of DIY waste water treatment plants that have been designed to be ideal for home use – above ground installation or below ground installation. The above ground system is the most cost effective and can be installed with minimal excavation and construction. The below ground installation is more aesthetically pleasing but requires excavation and civil works which makes it more expensive. The modular construction of the plants means that expanding them in the future is easy and all the mechanical equipment that you need to manage your plant is installed for easy access.

SewTreat’s DIY plants can also be installed as a cost effective alternative to septic tanks and soakaways. These plants are designed for small applications and are so easy to install that clients could it do it themselves which creates even more cost saving, although SewTreat can come out and do the installation for you.

SewTreat’s waste water treatment plants treat water biologically using an enhanced strain of bacteria that has been developed in-house by SewTreat’s expert team. The enhanced bacterial action in their plants ensures a highly effective treatment process that boasts a very low carbon footprint, minimal capital input and low maintenance requirements.

“In a nutshell, the bacteria digest all impurities and the wastewater is then cleansed. The treated wastewater can then be discharged or re-used for general non-potable uses,” says Coetzer. “SewTreat has developed a highly effective multiple strain bacteria range that gets added to our plants. This specifically bred bacteria feed on the complex substances in the wastewater, converting them into simpler substances which improves the final effluent on a reduced footprint.”

“There are of course several additional measures that people can take in their homes to save water if these measures are feasible but being able to re-use treated water to wash your car or water your garden means using water twice instead of watching it go down the drain,” says Coetzer.  “This can result in the biggest water savings of all.”

Lodge Operators: The Easiest Way for You to Save Water this Year

January 18th, 2017 Posted by Press Releases 0 thoughts on “Lodge Operators: The Easiest Way for You to Save Water this Year”

One of the main goals of any lodge, especially those located nearby or within nature conservation areas is saving water. However, this is not always easy and might require looking at water saving from a different angle. Theunis Coetzer, spokesman for local waste water treatment firm, SewTreat, provides a solution that will help you make water conservation an easy resolution to stick to this year.

“For lodge operators, saving water can simply be too difficult to implement for a number of reasons,” Coetzer says.  “But, reducing water consumption is something we all must take very seriously now. Although the country has received some very welcome rainfall recently, we are not in the clear yet with regards to water shortages.”

Unfortunately, although you can request this of your guests, you cannot control how much water they use when staying at your lodge. Additional water is also required to keep vehicles clean, swimming pools full and sparkling and gardens around the lodge lush and inviting. These and various additional factors related to the practical day to day requirement of your operation can make saving water seem like an impossible goal. SewTreat has the answer – manage your lodge’s waste sustainably and create treated water that can be re-used.

SewTreat has developed wastewater solutions that use natural biotechnology to create a sustainable green solution that can be tailored to any lodge’s needs.

Their Plastic HDPE Tank wastewater treatment plant range makes use of plastic ‘Jo-Jo’ type tanks that are connected in series or parallel depending on site requirements. The plant is wholly constructed and cold commissioned before delivery to client premises for quick and easy installation (a 50kl per day plant can be assembled on site in less than five days).

SewTreat’s DIY plants are designed for small applications such as households and lodges. They are so easy to install that clients could it do it themselves which creates even more cost saving, although SewTreat can carry out the installation. SewTreat offers two types of DIY plants – above ground installation or below ground installation. The above ground system is the most cost effective and can be installed with minimal excavation and construction required. The below ground installation is more aesthetically pleasing as it can covered with vegetation. The modular construction of the plants means that expanding them in the future is easy and they are gravity fed (depending on the level of the incoming pipe).

SewTreat’s waste water treatment plants treat water biologically using an enhanced strain of bacteria that has been developed in-house by SewTreat’s expert team. The enhanced bacterial action in their plants ensures a highly effective treatment process that boasts a very low carbon footprint, minimal capital input and low maintenance requirements.

Besides the environmental benefits, SewTreat’s product offering has been tailored to the operational needs of lodges operating in Africa. “We have developed our products and services to embrace our customers’ operating environments and the on-going demand for environmental, social and financial sustainable solutions,” Coetzer explains.

“For some lodges, being able to re-use previously discarded water will be a complete game changer in terms of water savings, knowing every time they use the non-potable water that they are doing their part will hopefully make water recycling a viable goal to reach in 2017,” Coetzer concludes.

SewTreat Helps Drive Client’s Commitment to Sustainability

December 1st, 2016 Posted by Press Releases 0 thoughts on “SewTreat Helps Drive Client’s Commitment to Sustainability”

Earlier this year, Mpumalanga based Security Company , CSC Tactical, committed to recycling 2.8 million liters of water per year. To help them reach their goal, SewTreat provided them with an innovative wastewater management solution.

 

CSC Tactical is a well-known security company with their head office based in Witbank and has recently moved to a new site which is a busy hub of activity comprising a function venue for hire, a large office space and overnight facilities for their security guards. Piet Cromhout, owner of CSC Tactical, identified the need for recycled water at the new site for irrigation and washing company vehicles. In addition this, Cromhout says that they were concerned about the effect that the current drought would have on their operations as they are dependent on  boreholes which created a water security risk that needed to be mitigated.

 

“Previously we had septic tanks installed but needed a solution that would allow us to  recycle and reuse as much water as possible to alleviate the need we have for our borehole water. SewTreat was the logical choice in providing us with this solution as their plants also ticked the boxes of low maintenance, low energy consumption and having an installation that was aesthetically pleasing” says Cromhout.

 

SewTreat conducted a site visit at the CSC Tactical premises to determine what their daily water consumption is. They found that CSC Tactical’s maximum water use is 7500 litres per day and proposed an underground 7500L plant from their DIY range. “This particular plant would be easy to install and maintain, uses minimal energy and provides recycled water that is safe to use for non-potable purposes,” explains SewTreat spokesman, Theunis Coetzer. In addition to this, says Coetzer, the plant is installed underground which means it can be covered with plants which some clients find is a more visually attractive option.

 

The way that the plant installed will work is illustrated below:

SewTreat implements the latest advancements in sustainable wastewater treatment which they combine with their own bacterial strains developed in-house. This helps homeowners and businesses to add an eco-friendly solution for recycling of black and grey water with efficient and affordable wastewater treatment solutions. “Our motto is to treat nature with nature through sustainable engineering solutions. This is evident in the biological technology in our plants and in their modular designs which makes them extremely easy to install and maintain – which is always a major concern,” says Coetzer.

 

Coetzer concludes by saying: “CSC Tactical is now able to recycle 2.8 million liters of water per year, which is commendable. They are truly environmentally responsible and an example to all local businesses of how they should take responsibility of their environmental footprint.”

SewTreat to Provide Eco-Friendly Wastewater Treatment Innovations to the Tourism Industry

November 10th, 2016 Posted by Press Releases 0 thoughts on “SewTreat to Provide Eco-Friendly Wastewater Treatment Innovations to the Tourism Industry”

By making use of the latest advancements in sustainable wastewater treatment combined with the creation of their own bacterial strains developed in-house, SewTreat is able to answer the needs of lodges in remote areas with efficient, affordable and eco-friendly wastewater treatment solutions.

 

SewTreat is a proudly South African company offering specialised, modular biological wastewater treatment plant designs tailor-made for the South African and African market. Their approach is based on return activated sludge technology incorporating submersed aeration media. This enhanced bacterial action ensures a highly effective treatment process boasting a very low carbon footprint, minimal capital input and low maintenance requirements.

 

“Our goal is to treat nature with nature through sustainable engineering solutions that are evident in our superior proprietary biological technology. The modular design of our treatment plants makes us a leader in providing wastewater treatment solutions for the African continent,” says SewTreat spokesman, Theunis Coetzer.

 

Coetzer explains that SewTreat’s products align directly with the trend towards biomimicry that environmentally conscious tourism operations have embraced in recent years. Biomimicry means learning from and then emulating natural forms, processes, and ecosystems to create more sustainable and healthier human technologies and designs. SewTreat has developed wastewater solutions that use natural biotechnology to create a sustainable green solution that can be tailored to any lodge’s needs.

 

In terms of the tourism industry there needs to be a solemn drive to ensure that we are custodians of our varied and diverse biospheres. By taking responsibility of the wastewater and recycling the 100% of the effluent, lodges can increase their irrigation capacity while being a responsible user of our scarcest resource, water.

 

“The earth is a closed system so we cannot import the resources we have exhausted, nor can we simply export the waste we create. If we look clean drinking water from this perspective, it becomes clear that we have to find ways of treating water in a way that makes it reusable,” Coetzer contends. “SewTreat has developed a highly effective multiple strain bacteria range that gets added to our plants. This specifically bred bacteria feed on the complex substances in the wastewater, converting them into simpler substances and improving final effluent with a reduced environmental footprint.”

 

He notes that globally, the composition of effluents discharged to receiving waters, is regulated by the national environment agencies. The legislation is concerned with the prevention of pollution and therefore sets concentration limits on dissolved organic carbon (as BOD or COD), nitrogen, phosphates and other compounds which cause eutrophication in receiving waters. It also attempts to limit the discharge of known toxic chemicals by setting allowable concentration limits in the effluent. “If we consider that 100% of the effluent can be recycled, if done properly, there is no doubt that through this we are providing large bank of water that previously may not have been considered as ‘safe’ for the environment or community.”

 

Biological wastewater treatment is an accepted practice used worldwide. The process involves confining naturally occurring bacteria at a very high concentration in the treatment process, whether it in plastic type, containerised type or civil constructed type treatment plants.

Their Plastic HDPE Tank wastewater treatment plant range makes use of plastic ‘Jo-Jo’ type tanks that are connected in series or parallel depending on site space requirements or layout. The plant is wholly constructed and cold commissioned before delivery to client premises. The installation time required on site is minimal – a 50kl per day plant can be assembled on site in less than five days. A guarantee of up to 20 years is offered on the tanks depending on the type of tanks used in the plant. “We developed this range based on a need we saw in the market for a more cost effective solution for sewage treatment,” Coetzer explains – although he notes that while the plastic plants are cost effective in term if capital expenditure, they do carry very high shipping costs and so he does not recommend them for installations outside of South Africa.

 

SewTreat’s DIY plants are a very cost effective alternative solution to septic tanks and soakaways and allow the final effluent to be reused. Coetzer explains; “These plants are designed for small applications such as households and lodges. They are so easy to install that clients could it do it themselves which creates even more cost saving, although we can do the installations for them as well.” SewTreat offers two types of DIY plants – above ground installation or below ground installation.

A Practical Way to Go Green

November 1st, 2016 Posted by Press Releases 0 thoughts on “A Practical Way to Go Green”

By making use of the latest advancements in sustainable wastewater treatment combined with the creation of their own bacterial strains developed in-house, SewTreat is helping homeowners to add an eco-friendly solution for recycling of black and grey water to both new and existing homes with efficient, affordable and eco-friendly wastewater treatment solutions.

 

“Our approach is to treat nature with nature through sustainable engineering solutions that are evident in our superior proprietary biological technology. The modular design of our treatment plants mean that they can be installed in any home easily and efficiently,” says SewTreat spokesman, Theunis Coetzer.

 

“Many people assume that green solutions for the home – beyond the water and electricity saving measures that one can do in your day to day life – would include amenities and architectural features that are costly to install and difficult to maintain. We offer a way to tackle wastewater management through easy-to-install plants that are highly cost effective. This provides a way for to homeowners to incorporate a sensible and practical green feature into their home and recycle 100% of previously discarded water. The savings that is being realised through the recycling the black and grey water can be as high as 50% of the water bill,” Coetzer explains.

 

SewTreat’s approach is based on return activated sludge technology incorporating submersed aeration media. This enhanced bacterial action ensures a highly effective treatment process boasting a very low carbon footprint, minimal capital input and low maintenance requirements.

 

In terms of the South African scenario, clean drinking water is purchased from a municipality. Around 80% of this water ends up in the municipal sewer with the discard into a municipal sewer also being charged for by the municipality. In essence homeowners pay twice for the same water. By installing a SewTreat DIY wastewater treatment system, the discard cost is eliminated and all the water that is treated can be reused for irrigation, washing your car and other non-potable uses around the house.

SewTreat offers two types of DIY plants – above ground installation or below ground installation. Both plants are commissioned, constructed and fully tested off site at their 5000m² manufacturing facility. The above ground system is the most cost effective and can be installed with minimal excavation and construction. The below ground installation is more aesthetically pleasing but requires excavation and civil works which makes it more expensive. The modular construction of the plants means that expanding them in the future is easy. All mechanical equipment is installed with easy access.

 

The SewTreat team consists of civil and process engineers, microbiologists, project planners and a network of distributors with over 35 years of experience in the field.  They are able to offer turnkey services which incorporate consultation, design, manufacturing, installation, construction and operational support to their clients that meet all legal and industry related compliance.

 

Although the company is newly formed, SewTreat has already become an established name synonymous with international expertise in providing quality products and services to all sectors throughout Sub-Saharan Africa. Coetzer credits their success to the fact that homeowners are becoming more educated when it comes to the installation of eco-friendly products in their home. “At the moment it would be fair to say that we are dealing with an educated public who can differentiate between ‘feel-good green’ and ‘practical green’. Our product represents the practical green measures that can be taken by providing an eco-friendly wastewater solution that is also highly energy efficient.”

Product Offering

 

SewTreat offers several modular waste water treatment plants tailored to meet the needs of industrial sized, mining and construction operations.

 

  1. Plastic HDPE Tank Waste water treatment plant

 

The plastic range makes use of plastic ‘Jo-Jo’ type tanks that are connected in series or parallel depending on site space requirements or layout. The plant is wholly constructed and cold commissioned before delivery to client premises.  The installation time required onsite is minimal – a 50kl per day plant can be assembled on site in less than five days. A guarantee of up to 20 years is offered on the tanks depending on the type of tanks used in the plant. “We developed this range based on a need we saw in the market for a more cost effective solution for sewage treatment.,” Coetzer explains, although he notes that while the plastic plants are cost effective in term if capital expenditure, the do carry very high shipping costs and so he does not recommend them for installations outside of South Africa.

 

  1. Containerized Waste water treatment plant

 

The containerized plant is well suited to rugged African conditions. The concept is based on a ‘plug and play’ design, Coetzer explains, saying that they are designed for ease of transport, security and modularity, taking into consideration that the plant may be moved to various locations. “The complete WWTP is built into ISO High Cube Containers. The plants are can be easily moved from site to site, can be easily expanded and have a once off cost to the client as they can be moved from site to site as needed,” says Coetzer.

 

“Our recent upgrade of our design makes this a very competitive option for onsite waste water treatment. The plant is wholly constructed and tested at our 5000m² under-roof facilities which ensures that all boxes are ticked in terms of quality control procedures. The containerized plant offers a life span of 15 to 20 years which is excellent for a plug and play solution,” says Coetzer explaining that installation literally requires only connecting of pipes to the waste water treatment plant.

 

  1. Civil Constructed Waste water treatment plant

 

Their civil constructed plants are designed and constructed mostly for large flow industrial and housing development applications. The plants are aesthetically pleasing as they are constructed underground and can be covered with vegetation and are entirely civil designed and constructed to exact civil engineering requirements. These plants boast several advantages for clients including the fact that the civil construction can be subcontracted to local contractors to reduce construction costs.

 

Coetzer explains that provision can also be made for easy plant expansion through simple modular and common wall construction and that if the plant is gravity-fed, the system can operate without electricity for up to 48 hours. This makes the product an effective alternative for remote operations, for countries with unreliable power supply, or where no municipal connection is available.

 

A Greener Approach

 

Biological waste water treatment is an accepted practice used worldwide. The process involves confining naturally occurring bacteria at a very high concentration in the treatment process, whether it is plastic type, containerized type of civil constructed type. From here this bacteria, together with some protozoa and other microbes (collectively referred to as activated sludge) are treated in an anaerobic and an aerobic process. They are then returned to the anaerobic phase to eliminate sludge accumulation and waste generation.

 

“In a nutshell, the bacteria digest all impurities and the wastewater is then cleansed. The treated wastewater or effluent can then be discharged to receiving waters – normally a river or the sea – or alternatively used for irrigation, flushing of toilets or general non-potable uses,” explains Coetzer. “SewTreat has developed a highly effective multiple strain bacteria range that gets added to our plants, this specifically bred bacteria feed on the complex substances in the wastewater, converting them into simpler substances, improving final effluent on a reduced footprint.”

 

He notes that globally, the composition of effluents discharged to receiving waters is regulated by the national environment agencies. The legislation is concerned with the prevention of pollution, and therefore sets concentration limits on dissolved organic carbon (as BOD or COD), nitrogen and phosphates and other compounds which cause eutrophication in receiving waters. It also attempts to limit the discharge of known toxic chemicals by setting allowable concentration limits in the effluent. “If we consider that 100% of the effluent can be recycled, if done properly, there is no doubt that through this we are providing large bank of water, which previously may not have been considered as ‘safe’ for the environment or community.”
