Increase The GPD Capacity of Your RO System
A membrane upgrade is actually quite easy on most reverse osmosis systems. Simply replace the membrane with the desired capacity and then properly size the flow restrictor to match the capacity of the membrane. These must be matched to keep the proper water flow over the membrane surface. Mis-matched membranes and flow restrictors will either cause excessive waste to the drain or premature membrane fouling. You will find flow restrictors to match the RO membranes we offer here on our web site.
Convert "Proprietary" RO Membrane to Standard
Many owners of "proprietary" style RO systems convert their systems to use a standard membrane housing and a standard RO membrane and in doing so they save a bundle of money and the product is easier to find. Visit our FAQ section here on our web site or contact us and we will answer your questions about converting your "proprietary" (non-standard) RO system to a standard system.
