I’m not sure what your reference to a chemical process was prompted by because I don’t think anyone has mentioned that before? Of course forcing
water through a membrane under high pressure isn’t a chemical process.
Apparently I do have enough pressure to force water through the membrane because the
Watermaker is meeting it’s rated output GPH rate and the product water is meeting the level of salinity required to satisfy the salinity detector, and it doesn’t taste at all salty. My
boat is in the ocean in
Maine, not in a lake or river. If it were not able to produce its rated output of fresh water at its
current operating pressure, I think the
Watermaker would automatically increase the pressure until it could, up to the limit of the 1/3hp
motor pushing the
pump. It will be interesting to see what feed
pump output pressure and system pressure I see when I get my
boat into warmer and saltier water. But for now, in its present location, it seems that 480 system pressure is enough for it to satisfy its rated output of between 16-17 GPH.
