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. 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.

 

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. “The team at SewTreat has extensive expertise throughout various disciplines and so we are able to offer turnkey services which incorporate consultation, design, manufacturing, installation, construction and operational support to our clients that meet all legal and industry related compliance.”

 

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. 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 they can be installed underground and 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).

 

Coetzer concludes 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 lodges move towards a greener future. Preventing further damage to the environment will require 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 one step in your contribution to sustainability where the long term beneficiaries will be Africa’s nature, wildlife and resources”

#FutureIsGreen: Eco-friendly wastewater can revolutionise SA hotel industry

November 7th, 2016 Posted by SewTreat in the News 0 thoughts on “#FutureIsGreen: Eco-friendly wastewater can revolutionise SA hotel industry”

The hospitality industry in SA has, in many instances, led the way for green initiatives and sustainable practice across the globe. While our young, emerging economy is mainly to thank for this, it’s also due to the inventive and responsible business ideas coming from South African entrepreneurs. Despite what responsible tourism and hospitality mean for the South African economy, it is also critically important for the well-being of our planet – an issue South Africa has clearly prioritised.

Why is biological wastewater treatment used?

November 7th, 2016 Posted by Biological Wastewater Treatment 0 thoughts on “Why is biological wastewater treatment used?”

Microorganisms and bacteria are microscopic, free-Living organisms that can reproduce at an enormous rate of if the proper environmental conditions are met. Microorganisms are the primary agents of biological wastewater treatment. Biological wastewater treatment is the use of bacteria to degrade and decompose organic materials during treatment.

 

  • Traditional WWTP’s have used the bacteria and microorganisms that exist naturally in sewage effluent to use as base for treatment of effluent.
  • 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 treatment.

Due to their growth, adaptability, and resilience, wastewater treatment systems rely on microorganisms to degrade organic material and produce clear effluent water. By harnessing the ability of microorganisms to tackle the source of larger issues – degrading odour – causing compounds, for example – biological wastewater treatment offers major advantages over alternative treatment strategies.

 

These advantages include:

  • Lower operating costs compared to alternatives
  • Efficient degradation and removal of organic and inorganic compounds
  • Improved flexibility to handle a wide range of wastewater characteristics and flows

 

The key, however, to any biological treatment system is ensuring that the existing microbial community has the right conditions to grow.

The Effect of Biological Wastewater Treatment on the Environment

November 3rd, 2016 Posted by Biological Wastewater Treatment 0 thoughts on “The Effect of Biological Wastewater Treatment on the Environment”

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 which cause eutrophication in receiving waters. This legislation also attempts to limit the discharge of known toxic chemicals by setting allowable concentration limits on 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.

In fact, innovative wastewater management can result in the redistribution of this water into the environment for irrigation, flushing of toilets and dust suppression, as well as to replenish rivers and catchments in our water infrastructure networks. The technology is so advanced today, that effluent can even be treated further to potable (drinking) water for areas where it is in short supply.

These types of water recycling programs not only have a highly positive impact on the availability of water but make it possible to enable previously non-consumable water to be used in key areas within community resulting in quality water for consumption and use in gardens, industry, etc.

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’s DIY plants are a very cost effective alternative solution to septic tanks and soakaways allowing 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.”

 

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. 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 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.

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.”
