RO membrane output

[mark]

And there's even a calculator, just put in your membrane rating, PSI and temperature:

the only problem with that is they are promoting there own membrain.

Dow is the industry standard and they are rated at 60psi/100psi the problem comes in when peole sell dow membrains and only tell you the higher flow and no pressure. say like a listing for a 100GPD membrain. so you buy it thinking this is the 60psi rating and when you run it the most you ever get is about 60gpd. the ones I use are the dow 100/160 and they do put out 160 gpd at 100 psi and about 75 degrees.

Both links refer to the Filmtec membrane which points to Dow.

Eitherway, charts and link was more to point out the roll off in output if the source supply is less than the spec'd pressure and temperature.

yup I find in the winter I get hit hard, water here is real cold as I am a short distance from the resavoir, thats why I have a 320GPD set up I probably only get about 150 during the winter.
