Is it possible to make a Reverse Osmosis water filter that doesn’t depend on electricity?
Im thinking of constructing an RO water filter in rural areas where there is no source of electricity. I know that reverse osmosis filters require pressure but Is there any cost effective way to to obtain the energy to pressurize water?
Basically your question becomes “How do I run a pump without electricity ?”.
Well, take off the motor and replace it with a crank, a water wheel, a wind turbine, steam engine, stirling engine, or something animal powered.
