Q: What is the target PSI to maximize rejection rate on a 3000 gpd? Does that target change based on incoming water temp? Asking for a friend.
A: The easy answer is....the higher the pressure the more efficient the operation of a membrane. Now the practical answer...the components of your system HAVE to be able to handle the pressure you are feeding with.
Therefore the target pressure should be as high as your unit components can COMFORTABLY handle
