Test Program for Physical Cleaning and Fouling Prevention in Reverse Osmosis Systems.

摘要

A number of in-situ physical cleaning methods were tested as alternatives to using chemicals to clean reverse osmosis and ultrafiltration membranes. Flow surging, air surging, continuous air addition and ultrasonic cavitation were used alone and in combination with each other as cleaning methods. Ultrasonic cavitation alone and in conjunction with flow surging were the most effective of the methods tested. (Author)
