Clean with high pH cleaner. Chlorine feed equipment and Chlorine Oxidation de-chlorination system. Abrasion of membrane by Improve pretreatment. Check all Crystalline Material filters for media leakage. ABNORMAL PERMEATE FLOW Permeate flow should be within 20% of the rated production, after correcting the feed water temperatures above or below 77°F. Check your permeate flow meter to determine the permeate flow rate.
