Micro Sewage Treatment Station for House Hold Waste Water

Published on by

Does anyone have any available technology for treating wastewater generated from approx 10 households?

We are actively looking for these micro sewage treatment stations to be provided to remote areas.

To areas that are disconnected from any municipal network, especially in Africa and Asia.

The Solution should be economical from both a Capex and Opex standpoints and easy to install in existing buildings/homes. Looking forward to see what solution are available in the market. Share technology details as well, to check the feasibility of the technology.

  1. The normal solution would be to connect the properties together into a suitably sized septic tank. If further treatment is required then a reed bed would be appropriate. Capex and opex are minimal compared with any other system.

  2. The Water Network research team has consolidated an answer to the above question. 
    Further input from members is welcome and appreciated.  
     

    A free  WWTP design generator tool  hosted on The Water Network is our suggestion for designing a wastewater treatment plant. 

    wtp design tool.pngAll you need to do is fill in the parameters and wait a few hours to get the complete design in your email. 

    The tool generates the best Wastewater Treatment Solution based on the information about the geographical region, COD, BOD, TSS, nutrients, water quality characteristics, population and flow parameters, etc.

    You can request an advanced design with the details stated above or a basic design which requires less information.

  11. We are currently manufacturing the NextGen septic system that treats up to 1200 gpd sewage flow from one or more households and produces clear, non-turbid treated water that can be reused in the toilet or for irrigation of crops. The system can operate with solar/ wind power, although in the US model, it uses household electrical power.

    Can send more info.

  12. Hello Laurent, As you see by my picture here on the side I am sitting with one of my old friends, who is a chief in Ghana, where I live and work almost half of each year.  In my companies in the states we have developed two technologies that deal with your problem.  The first and most economical is Electro-coagulation, which is a technology that operates off of a simple 110 volt electric system.  Go to www.eco-web.com then Editorials tab and finally Authors tab and go to the 9th to the 12th papers and you can read about it.  Also on that same site is a white paper on our technology called the Plasma Incubator Reactor.  It is more expensive but it can handle the entire sewage output of a small city in Africa, to read about it go to www.abescousin1.com or email me a gerrybeagles@aol.com and my US phone is 916-877-1553.

  15. Dear Laurent, we have decentralised biological SBR wastewater treatment systems from 4 to 2000 people plants. These plants are modular and can grow with your developments Please go to our website www.envirocontech.co.za or email me directly on hendrik@envirocontech.co.za for any queries and I will be happy to put together quotations and drawings for you. Please also see the following Links on http://www.enca.com/media/video/water-preservation-lies-toilet and , http://architectafrica.com/node/33973 . These links address your concerns and areas of enquiries directly. I look forward to hearing from you. Regards Hendrik Kuhn

  16. Dear Laurent, I have just seen your request. The project is a very low scale one and I would not advise a micro treatment plant. Instead I suggest you to install a septic tank followed by an absorption pit OR a leaching field. The individual septic tanks of 1.5 m3 should suffice for each dwelling. A communal septic tank could occupy a larger space and would require operation and maintenance systems. The size of rge AP would depend on the soil permeability. If you need any further assistance you may keep in touch with us Please. Regards. Chandansingh Chutoori, from Mauritius

  17. Dear Laurent,

    We are offer systems which operate completely autonomous. No electricity is required if there is sufficient slope for water to move down the system. If not the only thing required is a pump at the end of the system. Aeration occurs by natural airflow throuhg our filtermedia. This is a huge saving on OPEX and also CAPEX. We offer modular units which are easily sizable and capable of handling sewage from 1 house to small towns. Send me an e-mail at r.wagenveld@qmes.nl for more information.

  18. Dear Laurent,

    I have designed for my clients and testes over past 5 years Micro Sewage Treatment plants for about 15 to 40 people waste water. Originaly the designe was intended for oir exploration camps in Canada, but presently people are using this type of systems and building them for clients in differnet applications in different countries.

    The advatage fo the system is that it is very simple and any plumber could put it together with very little experience in water treatment. The system does not have any consumables and is designed to run with minimal service or maintenance for years.

    The system contains, grinding/mulching pump 2-3 stage of bio-filtration using Matala mats, very efficient aeration and polishing with ozone. Here is a link to a 35 second video which shows how brown sewege water is processed in to clean water, which with some additional filtration could be used for drinking.

  19. Dear Laurent,

    Many solutions are available, either compact (anaerobic or aerobic) or extensive (constructed wetland). Depending on your situation, I think you should prioritize extensive solution, as OPEX fit with remote areas and as this solution is often simpler for locals to fix.

    If not possible, you could focus on the compact solution. However you will need energy supply and, from my experience, be careful as equipments often suffer from a lack of maintenance which make the installation fail after a few months/years.

    Kind regards

    Philippe

  20. MABR (Membrane Aerated Biofilm Ractor) is the next generation decentralized treatment. Energy consumption is just 10 percent of conventional processes (about 0.1 kWhr per m3 treated), total nitrogen removal is built into the process, the plant is modular, enabling gradual expantion, effluent quality is very high, CAPEX and OPEX are low.

  22. Im interested in this question too. Its my view that distributed sewage treatment is the best way to provide sanitation and retain water in its natural catchment. However, in my experience any packaged treatment solution will benefit from a light-touch remote monitoring service via mobile wireless connection, the service will connect with an expert assiatant who will be able to guide and develop confidence witin the community beneffiting from the facility to understand why and how they should look after it. It wont come as a surprise to learn that we have developed such a capability on our WaterWorX platform.

    Our products are designed to easily integrate with traditioanl septic systems or can be provided in stand alons cargo containers for mobile treatment.

    Looking forward to continued dialogue.


  34. Already very good suggestions have been offered. One that is still missing is known as ROOT ZONE TREATMENT. It works on the principle of pre treating sewage in a septic tank or Imhoff Tank and allowing the effluent to flow laterally through a natural or prepared bed of soil over which plants like reeds are planted on normal top soil. The roots of the plants and the soil removes organic matter from the effluent which comes out clean and odourless at the other end. It can be used for any purpose other than drinking.

  35. Dear Laurent

    Following technique may be used for 10 household

    1. In Package Sewage Treatment Plants for10 household, a modified septic tank as an alternative to a septic tank/fosse septique. The reasons being that despite having plenty of land in which you can install a new septic tank and vertical sand filter, If you do not want to use up too much land, because to use the land for building a new house in a couple of years time. Also sand filters that take the output of septic tanks can often clog up in only a few years, meaning you have to remove all the sand and have it replaced. The sand used in these filters is special filtration sand and quiet expensive.
    1. Biological Wastewater systems from BioKube treat black and grey sewage water. The purified wastewater is safe to reuse. UV and after treatment remove E-coli and Nematodes. Main use is wastewater from villages, hotels, resorts, mines, oil camps and individual houses.
    2. (More than 10,I think small village)

    Small villages and remote communities often lack access to wastewater treatment plants with fully developed primary and secondary treatment capabilities. The design and development of new wastewater treatment plants for small communities and remote villages is time and resource intensive. Compared to other issues, wastewater is often seen as a secondary issue and access to funding is not always available or seen as to expensive for a small community.

    Water sources are sometimes contaminated with organic or septic matter. Citizens may therefore be confronted with a decline of water quality, pollution of local lakes and rivers, resulting in higher costs for importing of drinking water.

    Today, cost-effective small-scale sewage treatment plants for up to 50 inhabitants exist. Using a modular, turnkey construction system, the newest generation of small-scale community sewage treatment plants combines, multi-stage treatment systems and units such as:

    · Sequencing-Batch-Reactor (SBR) Processing

    · Membrane Reactor using Ultrafiltration

    · Continuous-Batch-Reactor (CBR) Processing

    · Short-Time-Batch-Reactor (STBR) Processing

    · Biofilm Method using growth bodies from plastic

    · Vented Biofilters for wastewater treatment

    · Fixed-bed plants for wastewater treatment

    · Plant based purification systems (etc.)

  36. We have a Phyco-remediation solution to use the sewage to grow Diatom algae and fish.

    If total wastewater flow from 10 households is about 5,000 liters per day ( sewage plus grey water), you would require a pond of about 150,000 liters ( 30 days storage / retention time). The pond can be 2 meters deep, so area would be 75 sq meters.

    No equipment or power supply is required, so the pond can be close by or away from the households.

    Pond need not be cemented, plastic sheet lining can be used if required.

    Natural ponds too can be used.

    Capex would be the cost of the pond, sewer pipe to the pond and pumping if required i.e., if gravity flow is not possible.

    Land should not be a problem in remote area, so this type of solution may be best suited, rather than an engineered solution requiring power supply, etc.

    Diatoms can be grown using our product Nualgi. 1 liter of Nualgi can treat 1 to 2 million liters of sewage, the total cost of Nualgi would be about $ 100 per liter.

    If fish can be grown in the pond, the income from sale of fish would help recoup the cost and you may make a profit or the treated water can be used for irrigation.

    This can be used together with other technologies, such as

    septic tanks - the overflow can go into the ponds for final treatment ;

    anaerobic treatment / biogas - the sludge can be put into the ponds to use the nutrients, N and P in the sludge.

    The basic principle is that sewage is digested food and contains nutrients, N and P. These should be put to use to grow food, since sewage is mainly water, growing fish is the best solution.

  37. I have found International Water Technologies in Canada provides the best microsytems I have found. Phone (902) 361-3135. pkiely@brightwatertech.co

    This is what we have for the Cabibbean after looking at the results they got in Canada.

  38. If a technological solution is required then the best option is a Rotating Biological Contactor (RBC) but the best low tech answer is to use septic tanks. If the effluent requires further treatment then direct it to a reed bed and or pond. Always look for a natural solution before employing systems which require spares and maintenance.

  39. Dear Laurent Selles

    I hope everything sees you well.

    This system can be modifyed to any fluid retention scale weather it be small,medium or large

     We have designed a fluid retention device which can be used for large holding tanks, flood defence, land retention, aqueducts and we are in the process of designing a self sufficient desalination tank for warm countries by using solar panels, water turbines .

     The system which we have designed is totally concrete free, can be installed on any terrain above ground, faster to install and requires minimal skill and machinery/plant.

     Benefits of using Neptune's products
     No Concrete required - Up to 40% cheaper than concrete
     Situated above ground for easy access
     Fast installation
     Low maintenance
     Minimal ground preparation
     Environmentally friendly 95% recyclable.
     We use recycled products where possible.
     Will last over 75 years
     Cladding can be installed to imitate grass, stone or other landscape effects.
     Solar panels to be installed around the system, this would pay for itself in the long run and or to be used as a backup to generate electricity.

     I hope to hear back soon,

     Best regards,

  40. Hi Laurent,

    BOSAQ is specialized in MBR technology for remote and extreme areas. Our most remote/extreme area is Antarctica where we have designed and operate a small MBR for treating grey and black water from about 30-40 people for the Belgian 'zero'-emission station Princess Elisabeth. The water coming out of the reactor is reused in the system. Simplicity of the systems we provide is crucial as remote areas do not provide a way for easy maintenance and demand simplicity in design. The system in Antarctica is solely running on solar power and has a low capex cost. If you are interested please contact us at info@bosaq.com.

  41. For Single house hold unit one can use Dewats based on recycle plastic drums of 3 nos 600 mm dia @250 ltr and 4 Nos 900 mm dia @575 ltr. With Connection pvc pipe of 75 mm dia. very easy and very cost effective, you can use the recycle water for irrigation and gardening purpose. there is no need of any energy consumption for this treatment. for further details contact on jgoyani@yahoo.com

  44. Hi Laurent;


    Please ahve a look at www.clearford.com we are currently doing just such a project in a village of 56 homes and a small local school having a population of between 250-300. We are putting in our smart digesters which are anaerobic biodigesters that do not use cultured bacteria, a pipe network and a structured wetland at the end so that the water can be reused for local agriculture. The project was done keeping in mind the paying capacity both in terms of CAPEX and OPEX and we currently anticipate OPEX will be in the order of INR 1000/month (USD 15-16/month) for the entire community excluding the cost of hiring a local handyman to maintain. You can reach me at sdeshpande@clearford.com and I have attached a document that describes the project.

  46. if the houses have septic tanks. there are boreactors that can be lowered and cost only about $1000 a house at distributor prices. to get lower odor, sludge, bod, cod, ammonia and tn.

    we are looking for dealers and distributors if there are any interested. biocleaner.com


  49. Hi Laurent,

    If your remote areas are like those I serve in, for Rotary WaSH projects, a group sanitation system for a cluster of homes is probably too expensive for them to afford either capital or operating cost; not to mention the lack of local technolgy for parts, service and repair. I would consider something much more simple and primitive, like a UDDT with solar dryer to accelerate solid waste, using diluted urine for home garden fertilizer, or maybe microflush toilet (popular in Ghana, we may be trying some in Tanzania). They can collectively have one person manage all, or by the household.

  52. Hello Mr. Laurent Selles, Greetings!

    We manufacture compact sewage treatment plants based on non biological - Electro-chemistry based STP (XERODROP- our brand). The system is compact and scalable. Simple automation is also possible to suite your requirements. The best part of the system is that it does not need open tanks and aeration systems and there is no pungent smell of the sewage. The output water is disinfected and ready to be used for gardens or irrigation or toilet flush or any non potable use.

    We would appreciate a direct email to me on aeolus.bioenergy@gmail.com for more details on the XERODROP systems for compact STP. We have attached herewith a photograph of a plant prepared as a donation to a rural school in India.

    We look forward for your valuable response.

    best regards,

    Niraj Mithani
