Filtration for Borehole Installations?

Published on by in Technology

In most developing countries, people rely on private water supply, mainly borehole installations as a source of drinking water. However, there is little or no treatment for borehole systems, which leaves the consumers exposed to various contaminants.

Is there a cheap and efficient filtration unit that can be installed on borehole systems to remove both chemical and microbiological contaminants? 

Are there any other inexpensive treatment methods for borehole systems?

  1. we supply small watermaker this is a "standard"filtration unit with a capacity of approx 2m3/h, possible to run on solar, additional we can add a UV system depending on waterpolution. feel free to contact us at info@dutchso.nl we have done more projects in Africa region.  

  2. Hi Temple,

    My company has a developed a system for developing countries called the CAFE (Clean Aqua For Everyone) System. It uses an innovative filter media which is filters out iron, manganese, arsenic and other heavy metals commonly found in bore water down to 1 micron without any additional chemicals. It is cost-effective, recyclable and lasts for the lifetime of the filtration system (over 20 years). The filter media is bio-resistant, self-cleaning, self-charging and self-sterilising and biofilm is unable to grow inside the filtration system. This technology is supplying drinking water to over 2,000,000 people across developing countries in Asia.

  3. I live in Kenya and we have promoted household water treatment and filtration at point of use. We have various options such as Waterguard (chlorine solution) Procter and Gamble Purifier for turbid water, Aquatab (in tablet form) , ceramic filters with silver lining. Even though the source water can be safe for drinking, water gets contaminated during transportation and storage at home.

  4. I have seen Aqua Guard (product sold by Perkin Elmer?) as a POU device at the tap/faucet in India.  It is not cheap (costs equivalent of 300 USD for the low-end device), and requires maintenance. 

  5. A major new & most effective/cost efficient LONG-TERM treatment process, is to have raw water pass through a "charcoal" bedding. How that's set up, will depend on how the bore-hole is laid out. Charcoal - in & of itself - can filter out/deal with both sediment & pathogen infections. Sediment, however, can eventually clog natural pores of the charcoal face, & thereby ultimately reduce its effectiveness/contribution to purification. So, by simply dding a few  drops of Aluminum Sulfate [Al2SO4)3], it causes sediment to drop to the bottom; for ease of periodic purging/removal, for other value-added use*. PLUS: Coating charcoal - in a Colloidal Silver "paint" form - can both prevent the clogging of charcoal pores (thus gaining much, much longer "effective use-life"), but also adding a truly MORE POTENT PATHOGEN-CONTROL WAY: TO BOTH INITIALLY PURIFY + then LEAVE AN EVEN MORE DURABLE/LONG-TERM COUNTER "ALL-PATHOGENIC FORM" SAFETY FACTOR IN POTABLE WATER! (E.g., even as it sits out in open ewers/other NON-purified vessels, awaiting final consumption/use!) {Special Note: *That water treatment sediment can serve as a valuable crop plant growing "mulch", as it helps in both nutrition & hydration of seeds/seedling cultivation! E.g., "more bang for the buck($)"!}

  6. For serious reduction of pathogens, within a few months, a sustainable water filter material of granulated ceramics will be available. It's too early to give a lot of details, but please know that it's on the way. Lab tests have verified log 6 reduction of pathogens, though the filter material will be available any where within the range of log 2 and log 6.

  10. I use Magnesium Oxide (MgO) prill beads to purify any drinking water. 

    The prill beads come from a deep mine in Nevada, USA. They are processed at 700 degrees which turns them into ceramic beads that will not dissolve in water. They last forever. 

    The beads place a positive charge in the water that shatters the magnetic bond that holds together any contaminants or pollutants (chlorine, fluoride, heavy metals: zinc, copper, lead, chromium-VI, pesticides, radiation, pharmaceuticals, black mold, Ecoli, bacterias, etc) and simply gasses them out of the water. It raises the water pH to 8.7, high alkalinity, high oxygen, and thins the water so that can penetrate the cell membranes and flush out your toxins. 

    As to hydration: 3 glasses of prill water is equal to drinking 1 gallon of reverse osmosis water.

    The cost is $40 US per household plus 3 gallon water container.

  11. It depends. First and foremost is protecting the borehole from any pollutants entry..so, waste water and sources of pollution have to be far away from getting any easy entry into the aquifer feeding the bore hole. Periodic checking of Borehole water has to be done. If it is sufficiently deep borehole in a large aquifer and water sample is safe, then no need of any further treatment unless any water sample shows impurities/ pollutants.

    If aquifer is shallow or water sample shows contaminants, then, suitable treatment is required depending upon what type of pollutant is reported.

    Hi Temple,

    Your observation is apt and needs an urgent solution as the majority of the borehole water are unsafe as researchers have testified. We, at MACJAMES in Nigeria, www.macjamesglobal.com, have designed and installed borehole water treatment plants, and treated borehole water for individual households, corporate organisation, etc. Our experience confirmed your observation and that led us to research, formulate and manufacture the human-centric innovation for such unsafe water challenges, SaferEx - Multiaction Water Purifier. Please follow the link and read about this innovation, it solves the unsafe borehole water problems efficiently and cost-effectively for the poor, medium-and high-income earners.

    1. Hi Chineye,

      You post about your product but unresponsive when one makes inquiries. I have written to you so many times. You only responded to the first that you will get back to me with details. No reply at all to my many reminders.

  14. Brazilian legislation establishes the following treatments for the treatment of public water supply through the well: filtration and chlorination. In the end, an analysis of the quality of the abstraction water is carried out to verify the efficiency of the proposed treatment, according to Brazilian water quality standards.

  15. The least expensive and most effective application is the RNA microbial species called ARCHAEA.  It does not require any filtering devices. No chemicals of any kind. Eliminates the need for chlorine.  All of the organic compounds are biodegraded into their elemental/nutrient form. Any and all toxic substances WILL be chelated into their non toxic/nutrient form.  There never has been a potable water shortage and never will.  The fresh water supply is intentionally being destroyed by municipalities and companies making huge profits from this criminal activity. So much misinformation and tradition. The common daily usage of natures self cleaning microbes is rarely allowed into the public arena.  See attachment for WATER. 

  17. Bonjour non malheureusement il n'existe aucune parade efficace contre la pollution des sources souterraines. Elles sont touchées par des pollutions dissoutes. Il faut déjà pouvoir identifier le type de pollution, son taux de pollution , sa fréquence, etc

    De nos jours l'environnement sert de poubelle à beaucoup de pollution. l'eau poatble va devenir une ressource rare. On en trouvera de moins en moins réellement potable et il faudra mettre des usines en amont du service de distribution pour purifier cette eau. 

     

    Hello unfortunately there is no effective solution against the pollution of groundwater sources. They are affected by dissolved impurities. It must already be able to identify the type of pollution, its rate of pollution, its frequency, etc.

    Today the environment is trash a lot of pollution. water poatble will become a scarce resource. We'll find less and less actually drinking and factories upstream from the distribution service is needed to purify the water. 

  18. The method of treatment (unit processes and operations) is majorly dependent on the contaminants locally in the place. Therefore, choosing a treatment method first requires lab tests. It is also good to know that some ground waters do not require treatment and that is why the water is distributed as is.

    Contaminants in water vary and removal is dependent on the contaminants present, filtering alone might not necessarily solve the problem.

  19. A cheap solution could be biodegradation with soil microbial activity. A system of different lays of topsoil installed in a vertical way, could be installed. It can be associated with a vegetated layer. This solution is not a 100% solution, but may reduce chemicals and microbiological contaminants, it could be tried.

  21. The price for a filtration system is dependent on the local water quality. If you have a non-risky contamination of the water you can use a simple filtration system.  Have you a risky contamination of the local water it can be you need a special filtration system. Above all the contamination with heavy metals, hydrocarbons, organic materials or microbiology do require a special treatment of the water and make the filtration system more expensive. For the price of a filtration system is also important to know the range of the water disinfection what is required local.

    I work together with people from your country since some years and we have developed some filtration systems what can handle the different local water qualities. If you need more information please feel free to contact me directly.

  22.  Check www.watsan.in. We have effective non-electricity based purifiers which works by micro-filtration, takes care of both pathogens, heavy metals like iron, arsenic and contaminants like fluoride. These systems can be adapted to borevwell lines too
