Toilet Water Purification

Published on by in Technology

I want to reuse the toilet water (urin+water) in my cluster.

Could you provide a solution idea or suggest a plant which purifies the urin water for reuse?

  1. Reverse osmosis plus chlorinaton which applies pressure to water on one side of a membrane allowing pure water to pass through, eliminates viruses, bacteria, protozoa, and pharmaceuticals. The water is then disinfected by ultra violet light (UV) or ozone and hydrogen peroxide. Finally, it is added to groundwater or surface water reservoirs where it stays for an average of 6 months to be further purified by natural processes. (This is done mainly to assuage public anxiety about drinking recycled water.) Once drawn from the groundwater or reservoir, the recycled water goes through the standard water purification process all drinking water .​Urine is 95% water, which 2.5% is urea and 2.5% is a mixture of hormones, enzymes and salts. Urine comprises of a few toxins that are not toxic enough to cause any harm to the body. There are numerous ways of filtering urine in order to drink it for survival.

    "To pull pure water out of urine, the system uses forward osmosis, which, as the name implies, works in the opposite direction of the reverse osmosis systems found at many kitchen sinks. Forward osmosis uses a concentrated salt or sugar solution to draw the water out of urine. Next, enzymes in a bioreactor convert the leftover urea into ammonia, which feeds into an electro chemical cell that uses the ammonia to generate electricity."

  3. Dear Sir:

    Our company has been specializing in re-cycling water from waste systems for over 20 years.

    We have a system that can handle either 20 cubic metres a day or a system that is a lot bigger that handles 50 cubic metres a day. All biological - no chemicals  - natural system that uses micro biota.

    The water can be used for hand washing, showers, toilet flushing or vegetable gardens and fruit trees.

  4. The City of Windhoek in Namibia has been recycling wastewater for reuse since around 1960's. You should be able to google them. They do total recycling of all wastewater. The company that does the work is called WINGOC.

  6. It depends on where youwould like to reuse it.If for human use then RO with chlorination may do.If not then simple Ultra filtration method may help.Please get the chemical analysis of water to be treated before taking any firm decision.

    1. Dear Abhayanker ji please let me know the simple technology. Do you have any plant or system? If yes please write me my mail : amatyasp@gmail.com

       

  7. You can verywell go for a sewage treatment plant to meet your requirement. Based on the capacity and available area, the plant can be designed.

  8. For human consumption or just for Irrigation, if so we have plants that can that. What is the capacity per day... and what specific effluent requirements do you have? www.eecusa.com 

     

  9. Dear Shiva,

    We re-purify any kind of wastewater meeting all standards of drinking water, with very low operating costs for maintenance and just renewable low power energy, zero GHG emissions and no odors neither noise, one 5th space than conventional WWTP's and not hazardous waste.

    We have 15 years experience with more than 15 plants built and installed plants with more than 100 lps capacity.

    We warrant our technology and cost-benefit-satisfaction of our clients, hoping get in touch for further support for your need, thanks.

    Kind Regards,

  10. We at SolEco Africa can supply you with our 100% organic Solutek that will solve all your problems and leave you with A grade water suitable for irrigation etc, you will then need to use various filters etc to purify to drinking water standards. please visit www.solecoafrica.co.za or call me on 0839742168

  12. Hello French

    Aucune plante n'a vocation à purifier l'eau. Elle absorbe par son complexe racinaire de l'eau et tout ou partie de la pollution dissoute que cette eau contient. Si cette pollution est importante, le corps de la plante  va saturer de cette pollution et mourrir.

    Tout le liquide qui passe entre les racines des plantes, va laisser sur son passage une partie de la pollution qui sera automatiquement absorbée par le passage du liquide suivant. 

    Un tertre de terre sert de filtre mais n'élimine pas la pollution, il l'a stocke.

    Par contre les plantes sont gourmandes de certaines pollutions tel que l'urine. Mais et c'est toujours pareil, il faut que l'urine soit très diluée, qu'elle ne soit pas exposée trop longtemps à l'oxygène car l'urée se transforme en ammoniaque, un produit toxique pour les plantes.

    Comme tout ce qui est biologique, il faut de la nuance et des quantités infimes

    English

    No plant is meant to purify water. It absorbs by its root complex water and all or part of the dissolved pollution that this water contains. If this pollution is important, the body of the plant will saturate this pollution and die.

    All the liquid that passes between the roots of plants, will leave in its path a portion of the pollution that will be automatically absorbed by the passage of the next liquid.

    A mound of earth serves as a filter but does not eliminate pollution, he stored it.

    On the other hand, plants are greedy for certain pollutions such as urine. But it is always the same, the urine must be very diluted, it is not exposed too long to oxygen because the urea is transformed into ammonia, a toxic product for plants.

    Like everything that is organic, it takes nuance and minute amounts

    1. All you have said needs to be repeated many times to those not having a microbiological background. I believe a key factor and a direct answer to his question would be called "A microbial balance".  DNA microbes will biodegrade simple organic compounds. Their ph range is also very limited. To compliment total soil health the microbial balance must contain RNA microbes. They are the only microbe with the genetic code to reduce all organic compounds into their elemental form. In addition they will chelate any and all toxic metal compounds.  When balance is present  and within known parameters the urine will be converted to elemental nitrogen and hydrogen. The same process will convert the solid waste and toilet paper also into elements. Independent labs are suggested. 40 years of testing with zero pathogens and zero toxic compounds.  Great point on soil does not eliminate waste pollution.  The microbes do.   (a word assist for you. "If pollution is harmful, the plant will absorb the pollution and the plant will die).   Bon Chance!   Gui.

    2. All water that we drink already was polluted more than four times in the past, the problem is that humans contamination has overpassed the natural capacity of Earth, so it's our responsibility to re-purify it with sustainability.

      1. Allow me to fill in the facts. The centralized processing of water and waste water is the only problem. Nature has much more capacity than you could ever imagine. The US first error was using chlorine to kill pathogens. In the 1920,s our microbiological technology was still quite new. If the chlorine was not in the treatment cycle it would clean 100% of the water and waste and be pumped back into the fresh water systems. No more need to run the water table down or build $billion desalination facilities.  In regards to Total trash/pollution. The UN did a study and estimated 400 billion pounds of man made waste a year. Nature was estimated at 600 billion pounds a year. Together they equal 1 Trillion pounds  a year. = 1x10 to the 12th. The earths microbial capacity to biodegrade all organic compounds is 1x10 to the 24th pounds per year.  So you can see how silly that statement was.

         This information is kept secret in well protected facilities. We now call them libraries.    

  13. Hi Shiva - your reference to urine water, is this diverted urine or the total of what is coming from the toilet flush, typically referred to as black water? Then do you want to return the water to use as flush water to operate the toilet flush mechanism?

    What is size of cluster? how many people per day residing and others that may be using the toilets?

    This is all necessary information to ensure you get a system that can handle the load and can treat the water to the required end use requirement.

    Then the preferred option to fit space and site conditions can be selected.

    You can contact me directly if necessary, gary@dikubu.co.za

  15. Dear Shiva, sorry but what do you mean by "cluster"? Or more scientific: Could you supply information on the water quality you need to reach in the treated water?
