Re: Dessalator Watermakers & Filmtec Membranes

Filmtec states the following about the SW30 2540 membrane, "This membrane is rated for a maximum 700 gallons per day, we use it in our watermakers to produce actual 21 gallons per hour from standard seawater (35000 ppm). In brackish water, freshwater production will increase but you should not exceed 30 gallons per hour or 700 gallons per day."
So, I believe that if you turn the pressure down so that the flow rate does not exceed the rating for the sum of the flow rates of your membrane array, you'll be doing exactly what Filmtec states above.
Here are the flow rates of common SW30 membranes:
