Hi Prabina;

I suspect what you need is both something that will work in disaster like situations, can give clean water for a community, is portable, easy to install and operate. 

I used to use one such product that was a UF based manual backwash unit. Depending on turbidity levels it could produce 500-700L per hour. Note as a UF based unit it will not remove things dissolved in the water but will remove most bacteria and a good amount of the viral load as well as the turbidity. the unit requires about a metre of head pressure to operate so the water to be cleaned will have to be raised above the unit.

Let me know if interested and i will connect you to a supplier in India.
