Clean with acid cleaners. Optimize pretreatment for colloid Colloidal Fouling removal. Clean with high pH anionic cleaners. Increase acid addition and Scaling (CaSO4, CaSO3, BaSO4, antiscalant dosage for CaVO3 and SiO2) CaCO4. Reduce recovery. Clean with acid cleaners dosage of Sodium Bi-Sulfate. Membrane fouling Continuous feed of Sodium Biological Fouling at reduced pH. Chlorination and de-chlorination. Replace cartridge filters. Activated Carbon or other Organic Fouling pretreatment. Clean with high pH cleaner. Check 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.
