Closed end reverse osmosis unit
A closed reverse osmosis system comprises an end cap that has a pressure vessel portion adapted to inhibit flow of feed fluid, a permeate fluid conduit that extends from a permeate fluid flow path, and a waste fluid chamber that extends from a waste fluid flow path.
1 . An end cap for a filtration system comprising:
a pressure vessel cap portion adapted to inhibit flow of feed fluid;
a permeate fluid chamber that extends from a permeate fluid flow path; and
a waste fluid chamber that extends from a waste fluid flow path.
2 . The cap of claim 1 , wherein the pressure vessel cap portion comprises a waste fluid flange that at least partially directs waste fluid into the waste fluid chamber.
3 . The cap of claim 2 , wherein the pressure vessel cap further comprises a permeate flange that at least partially directs permeate into the permeate chamber.
4 . The cap of claim 3 , wherein both the permeate flange and the waste fluid flange have grooves adapted to accept a Vitaulic™ fitting.
5 . The cap of claim 1 , further comprising an o-ring that substantially inhibits flow of the feed fluid.
6 . The cap of claim 1 , further comprising outlets for the waste fluid and for the permeate.
7 . The cap of claim 1 , wherein the waste fluid chamber comprises two interconnected segments.
8 . The cap of claim 1 , further comprising a waste fluid flange that extends along an inside wall of a filtration housing to inhibit flow of feed fluid.
