Reverse Osmosis Membrane Cleaning.
Abstract
Tests involving the cleaning of both membrane pieces and spiral wound modules clearly point out the effectiveness of sonic and ultrasonic cleaning over other cleaning techniques. Membrane pieces displayed nearly new characteristics after treatment in an ultrasonic bath while more traditionally cleaned pieces at best yielded only 50% improvements over their fouled conditions. Even tightly wound spiral elements reacted quickly and positively to sonic and ultrasonic stimulation. Flow rates and operating pressures returned to normal ranges within a few minutes of beginning the cleaning cycle. Backflushing and chemical cleaning attempts could not even begin to compare with the reproducible results obtained by sonic cleaning.
