Abstract:
1. A reverse osmosis system comprising: a pressure tank having a first end and a second end, the pressure tank has a first volume adjacent to the first end and a second volume adjacent to the second end and a third volume between the first volume and the second volume; a fluid passage fluidically coupling the second volume to the first volume; a plurality of membrane housings fluidically coupling the first volume and second volume; a first tube sheet preventing direct flow of brine between the second volume and third volume; a fluid distribution plate adjacent the first end of the pressure tank and separating the first volume and third volume; a plurality of membranes each disposed within a respective one of the plurality of membrane housings in the third volume, said plurality of membranes generating permeate; a permeate manifold receiving permeate from the membranes and fluidically communicating permeate out of the pressure tank; a feed line coupling feed fluid into the pressure tank; an input manifold fluidically coupled to the feed line, the input manifold has a plurality of outlets disposed adjacent to first input ends of the plurality of membranes nearest the first end of the pressure tank within the third volume; a first pump pressurizing the feed line; a second pump disposed within the pressure tank circulating brine fluid from the second volume through the fluid passage.
