I'm trying to breathe life into an old GE Osmonics system. The feed and pressure pumps were shot, so I'm starting with a clean slate. I'm setting it up to run two of the double membrane 4x40 vessels in parallel. I have a procon 11gpm@250 psi pressure pump and a pompco 1/2hp 20gpm pompco recirculation pump. Something like a H2O hobby, but a little bigger. My question involves where to locate the recirculation pump and where to draw concentrate. Should the recirculaion pump inlet be directly after the pressure pump and return between the two pumps or should the recirculation pump draw from the vessel outlet and return to the vessel inlet? I'm also thinking that I should draw concentrate after the recirculation pump outlet.
Any thoughts on design would be appreciated.
Also, the system came with 5 vessels. I would'nt mind selling a couple of them.
