  1. Dear Mr. Subbarao,

    Humbly and respectfully, as a response to your request I suggest the same solution proposed to a Texas Company (U.S.A).

    See: David Publishing company www.davidpublisher.com or Academia.edu/desalination.

     

    1) New method for desalination of seawater (Journal of chemistry and chemical engineering september 2013)

     

    2) Other seawater desalination method (Journal of chemistry and chemical engineering January 2016)

     

    3) Another seawater Desalination process (Journal of Environmental Science and Engineering September 2016

     

     India, in my opinion is the country that could benefit most from this research, given its scientific infrastructure that will allow the rapid and easy recycling of chemical compounds involved in desalination processes, the mild climate. Just imagine cultivating 3,000 hectares of bamboo an activity associated with desalination plus recycling compounds can ensure the production of 5000 megawatts of clean energy is better than dangerous nuclear energy. In addition to the water available for subsistence agriculture and other needs.

     

     

  2. Please visit www.aquathin.com .  Click Dealers.  Scroll to South Africa where you will read about our antimicrobial filters treating cholera...and more.  Then review Aquathin's list of credentials, certifications, and lab analysis.  Thank you.

  5. What is the source water quality? What is the flow rate or where will the treatment be utilized (municipal, POE, POU, etc)

  6. Dear Dr Subbarao,

    When India addresses the supply of clean, drinkable and affordable water, it must look at the full picture of fresh water supply on one side, and fresh water consumption on the other.

    70% of it is absorbed by agriculture.

    India is hot and arid in many provinces, where reducing the water consumption in agriculture is the squaring of the circle, because evaporation in these areas is 50% of the fresh water supply.

    Conclusion: reduce evaporation in irrigation by use of all possible clean and sustainable technologies.

    As an example: take a look at www.guilspare.com.

    Good luck and best regards,

    Laurent H. Selles

  7. Dear Dr. Subbarao and participants of this discussion,

        I cannot tell you how strange and abnormal is the understanding of human beings when it comes to find a supplement of potable water. Please allow me to present to you some basic facts.

         All the available potable for all human beings in all the countries of this planet is provided from rain water. The Lord in His Kindness is fully aware that we are terribly helpless, so He established a very simple process relying on room temperature evaporation to feed all the mouths of all His creatures, and fill all His rivers.

        However our beloved human beings are adamant not to imitate Their Creator.

        We succeeded to put together an equipment which is a direct imitation of The Lord room temperature evaporation, we made sure not to patent our design, and not to allow anyone to patent it. We are providing the details on our website www.naturalseawaterdesalination.com and we are showing to everyone how successful is our equipment in water desalination. All what is needed now is "go ahead and do the same". Then one question is imposing itself: Who are the inhabitants of this planet???

    1. Dear Dr. Subbarao,

        Thank you for your kind invitation. My understanding: Reverse Osmosis is now a rejected process for water desalination, however there is now a huge multitude of false ideas coming in place, it might need some time until a process could show some leadership, perseverance, and effective success.

    2. Thank U Maher Louis. Do you have any Indian business partner whom we can invite to exhibit in International Innovation Fair coming up at Visakhapatnam, India, from 9-11th September 2017. If you do not have an Indian partner, would you like to participate yrself? We will give you space free of charge in the fair.

  9. Dear Mr. Subbarao:

    I humbly suggesto you to use the power of Nature, Phytodepuration + The Sun. Constructed Wetlands of HFF (Helophyte Flotating Filter) combined with UV, from the sun for the pathogenic bacteria removal. The limitation for this kind of system is the number of persons it can be used for, due to the area it requires. That area for hot regions it will be minor than in temperate regions. According to the calculations of my mentor D. Jesús Fernández González (http://www.upm.es/observatorio/vi/index.jsp?pageac=investigador.jsp&idInvestigador=6432I ) who has developed the system, it will be feasible in Europe or USA for 15.000 equivalent inhabitants. I thing for India it will be feasible for higher population figures.  If there aren't limitations for the area that can be used for more. Cheap to be built, and cheaper than any other system on its maintenance due to its minimal energy requirements.

    Regards to @ll.

  10. FilterClear is a very simple yet effective improvement to conventional sand filtration. Instead of using just sand, or sand and anthracite, FilterClear uses 4 layers of media, of decreasing particle size, which re-stratify after every backwash. These 4 layers give much finer filtration, are more resilient against blockage and can operate at much higher filtration rates than conventional sand filters. FilterClear is used as pre-treatment for desalination or instead of sand filters on conventional water treatment.

    We have plants in India and I will be in Mumbai and Bengaluru for the next 8 days .

    2. Hi, I am from Bangalore and we like to introduce  a products developed from natural herbs to treat water like floculant and biocides. Which can remove coliforms like E-coils, If you like to get demo of this product in Bangalore we can meet. Even we have an alternate for lime concentrate which is used to balance pH in ETP very effective and sludge is very less compared to the regular lime. Contact 9844982951

  12. Dear Sir - WaterQuest Hydroresources enables access to clean fresh water from perennial  climate resilient sources using innovative Artificial intelligence based technology alongwith eco conscious drilling technology. We have been named as top 10 most innovative company by Fast Company Magazine as well as we have been successfully reviewed by Dr. R A Mashelkar Expert Standing committee of Ministry of Drinking Water  Sanitation, GOvt of India as an Innovative technology to provide for clean drinking water. http://skyquestt.com/waterquest/

  15. Sir, trash can be used as fuel in a gasification system which can not only power a RO plant but also use surplus heat for distillation.    Neal@newrangepower.
