I am well aware of the mineral used to purify water from nitrates, bacteria and other contaminants in tube wells, in household and other filters. But this mineral is produced very far from you.
I advise you to select and test minerals with similar properties in India. Simple filters can be manufactured or collected in every family, community or institution. I have been using such filters for more than 20 years.

1. for getting rid of bacteria in tube wells or underground aquefiers  if contaminated is by adding small amounts of sodium hyperchlorite for 6-12 months which is freely available in india 

2. for house holds i am manufacturing in india  a UV WATER FILTER THE EXPORT PRICE OF WHICH IS US $ 10 EACH FOB

any body interested can contact me to send a photo of the product & it is better than RO which requires regular change of filter at extra cost

3. it is meant for 90% of the population who cannot afford the expensive RO

The mineral, which I use for many years, is produced in the north-west of Russia. In Russia, it is widely used for water treatment. But its delivery from Russia in India is problematic, especially in winter. India is rich in various minerals. Therefore, I advised you to select suitable minerals in India and test them  you yourself. Maybe with my recomendations. But my recomendations, knowledge and practical experience - only when developing a joint project.

Thank you Sir. Can you please share your study/practice report to me so that I can try to replicate here ?

Dear  Praveen Subramani ,

Water should be not only clean, but also biologically active (useful).
I can share the mineral sorbents, homemade simple filters for water purification and saturation with useful mineralic agents as well as recommendations for their testing and application. But these services must be paid in advance.

Kind Regards,
Chemist-ecologist Vitalijus Gediminas
