ro build

[Shon]

I'm sure you could build one of this size but at what cost, I don't know. I bought my 600 GPH machine from H2O. When planning your build make a complete list of everything you need. If you start buying parts and pieces as you go you may find you are spending way more then you expected. One of the things I don't see included in some of the home made units is a wash tank, a way to protect it from to high of a temperature and a heater if you are not going to let the pump create the heat as it washes.

whats the purpose of the wash tank.when i look at smaller units i see the option just wondering the purpose as they come with or without.i also wondering about the idea of adding a recirculating pump and what size pump required ,does it need to be more sized or less sized then the high pressure pump

When you do a wash on the membrane you need to mix the soap with permeate to reach a ph level of about 11.5 Then that solution circulates through the membrane till it reaches about 104 degrees. You then drain the membrane and do a rinse with just permeate.

Those who order an RO without a wash tank, use a suitable tank or bucket of their own.
