I am currently working on decentralised options for water and wastewater treatment in my hometown.
What are the possible energy-efficient and cost-effective optimisation options for the onsite wastewater treatment system?
My intention is to treat (and reuse domestic wastewater) to at best drinking water quality.
The dominant onsite treatment system in the targeted area are the septic tanks. l am, thus, looking for alternative technologies or setups that can be adapted to reclaim wastewater from this system.
Dear Tendai, We have multiple decentralized WWT solutions. Please contact me at iwilf@fluencecorp.com and be happy to discuss further. Best regards, Ilan Wilf
cheapest (both CAPEX & OPEX) and safe solution is tertiary treatment of effluent from septic tanks with constructed wetlands, but never to WHO drinking water standards
Dear Tendai, I have the Clarus Fusion STP, a factory manufactured unit of varying sizes that biologically treats grey and black water and then the effluent grey water from the system can be reused for irrigation etc. It is not potable but further treatment can render this so. Very low power consumption and an operate from solar. Please see my website www,maskamwater.com
We are based in RSA and have Dealers in Central and Southern Africa. At present seeking a Dealer in Zimbabwe.
To achieve the drinking water quality from wastewater. Please check the New Water in Singapore. It would be secondary process plus MF~RO or MBR~RO. Other process can't give you a drinking water quality.

Onsite (or decentralized) wastewater treatment systems are used to treat wastewater from a home or business and return treated wastewater back into the receiving environment. They are typically referred to as septic systems, because most involve a septic tank for partial treatment.
The most common and traditional septic systems consist of a septic tank that gravity flows to a soil adsorption field for final treatment and dispersal. The septic tank allows particulate matter to settle to the bottom of the tank so that large solids do not plug the drain field. An effluent screen placed in the outlet of the septic tank is used to filter suspended solids out of the effluent. Final treatment and dispersal of the wastewater takes place in the soil adsorption filed.
A non-traditional system performs the same basic actions as the conventional septic systems. Differences arise when location, space, laws and regulations, soil type, and/or quantity of wastewater being treated become a limiting factor. A non-traditional system in this case refers to any OWTS that uses pumps or advanced treatment. These systems use technologies that require greater frequency of operation and maintenance.
RBC is our preferred offering for decentralised plant, its low power requirement coupled with easy maintenance and very stable process make it perfect for your application. It can be added to existing septic tanks too. The treated water is perfect for irrigation. We have WTP's for treating any water too
you can treat with our biocleaner system to bod none detect and cod less than 5 ppm and tn at none detect and tp below 0.02. then pass through limestone filter. go through an up flow sand filter. this will get rid of pathogens including helminth eggs. there will be no odor from the water or from the plant. no sludge to get rid of. all green. very convenient and no need to buy any chemical. tiny energy foot print. cheers
If you have locally available biomass such as waste wood, you can produce heat and energy on a small scale for each household or neighborhood via gasification. The byproduct heat can distill your waste water to clean water. This at the same time you provide electricity. Neal@newrangepower.com
Rachel Bohrer wrote a M.S. thesis on this subject in the year 2000. It does specifically cover freezing conditions but most of her information covers all conditions. This is an excellent study and even though technology has improved a little in the last 17 years it is well worth reading. You will find it at:
My personal view on the best option for decentralised wastewater treatment is to provide a shallow sewerage system preferably using gravity flow to a packaged modular treatment plant providing primary settlement and secondary membrane filtration, or biological treatment. The effluent from the treatment plant is nutrient rich and can be used for direct irrigation of agricultural crops, public and private gardens. The small fraction of demand requiring potable treatment can then be provided as point of entry treatment in individual homes and communal properties. This system will be much lower cost than treating the whole recycled supply to drinking water standards. I'm particularly interested in promoting this solution because it will require a higher level of distributed monitoring and this will be provided by sensors and actuators connected via IOT (Internet of Things) technologies.
Hello the process "Biological pit " is all suitable for your search. A minimum of ground grip, a consequent volume for a purification performance of more than 98%. The liquid at the exit of the process must be rejected on a green outlet which supplements the purification treatment of the upstream biotechnology, purifying the soil of the dissolved pollution (the urine)

EEC Global Operation LLC www.eecusa.com Once we know the flow and inlet paramters we can take a look at the project and combined MBR and final effluent treatment so to make water suitable for human consumption. Send an email to EEC att: Bjorn Sundbakken at eec@eecusa.com
