Removal of Silica Fouling From Membrane Elements – SPA

An 8-MGD water reclamation system in Northern California was experiencing membrane fouling that was increasing the required feed pressure to produce water. A membrane autopsy showed that the fouling was caused by silica scale. The system consisted of three trains, each designed to produce 1850 gpm of permeate at a feed pressure of 145 psi.

Membrane Autopsy: Why, When and How – SPA

Why do a Membrane Autopsy? The word autopsy derives from the Greek word “autopsia” which means “to see with one’s own eyes.” Autopsies can identify specific foulants and scalants on the membrane surface, and they can determine the presence of chemical or mechanical damage that has occurred during operation. The data and conclusions from an
