29 Jan Procedures for cleaning reverse osmosis membranes with fouling, organic matter and colloidal source material
The purpose of RO membranes autopsy is knowing what caused the membrane fouling, affecting working conditions in the plant. Under certain operating conditions it is usual that the surface of the membranes and spacer materials soil, causing a decrease of salt rejection, a change in permeate water characteristics and an increase in differential pressure. A situation of increased product flow and increased salt passage could also be possible, due to an oxidation or abrasion of the membrane surface.
