I. About Reverse Osmosis Membrane Life Expectancy

Typically RO membranes have an estimated life expectancy of 2~3 years. Many factors determine an RO membrane's life expectancy, such as feed water quality and frequency of use. Methods for cleaning RO membranes are often not cost effective for residential RO systems

II. 
About Reverse Osmosis Membrane Fouling


All reverse osmosis membranes lose their performance and foul over time. Suspended solids, microorganisms, and and other particles build-up on the RO membrane surface and cause fouling. Examples of suspended solids often found in feed water include oil, silica, clay, iron, sulfur and acids.
