Avista OSCAR Restores Nanofiltration System

Substantial Savings in Membrane Replacement Costs and Downtime.

BACKGROUND

A seawater plant operator was experiencing issues with its nano-filtration plant, which showed poor permeate flow and poor rejection.

A membrane was sent to the Avista™ Center of Excellence for autopsy and the problem was identified as a breakthrough of incompatible coagulant from the multi-media filter upstream. This kind of foulant is extremely persistent, usually requires extensive cleaning protocols to remove, and often renders membrane elements irrecoverable.
