I'm thinking to buy the component individually.
I am interested in Dual 100gpd DOW Filmtec membrane in a series ( waste from membrane 1 feed into membrane 2).
Incoming water pressure is 65psi, ~260ppm
What size flow restrictor do i need? I believe i just need to restrict the flow for the membrane 2 waste line. Is this correct? I'm guessing i need 550cc size?
How do i calculate the Pure to Waste ratio? I don't think number of stages (sediment, carbon, etc) matter for this. I'm hoping to get at least 1:1. Some system claimed 1.5:1 or even 2:1. Is this because they use boaster pump to increase the incoming psi?
