ABOUT RO MEMBRANE FOULING
All reverse osmosis membranes lose their performance and will foul over time. One of the primary reasons for RO membrane fouling is because of substances that deposit on the reverse osmosis membrane surface. The RO membrane elements can become fouled by suspended solids, microorganisms, and build-up from mineral scale. Examples of suspended solids often found in feed water can include oil, silica, clay, iron, sulfur and acids. To increase the life of your RO membrane, reduce most of these suspended solids before the water enters the membrane. Use a 5 micron carbon prefilter cartridge before the reverse osmosis membrane. This will help, but may not completely remove all suspended solids that cause a RO membrane to foul.
