I think my question is how much water can be purified before the filters clog up.. Granted, they are thin, and therefore easily changeable, but if nothing but water molecules can permeate each sheet, they will clog quickly.. Hawk
I have a good deal of experience in working with water purification systems with the pharmaceuticals and other industries. Even in processing city water for consumption by the pharma plant, before the water gets to the membrane it goes through sand filters, then is pH neutralized. The sand filters are connected with at least two banks in parallel. They are removed from service and backwashed automatically as back pressure increases, with the process continuing on the alternate filter bank.

Desalinization would likely have the same processing but include settlement ponds and skimmers in the feed sequence.
