Hi !

I am looking to build a cost effective small RO system that would run on a 12V battery.

My goal is to remove at least 10 GPH of pure water and to concentrate (40°F) sap from 2 to 4 % Brix.

What are my options ? I have limited choices for the pump/motor, which limit the membranes choices...

Any suggestions, commentaries, advices will help me.

Thank you !


At the moment my parts list looks like this, but I am not sure at all :

Booster pump (36V) :
