Ultrasonic Enhanced Cleaning of Fouled Membrane Elements Fitted with Innovative Spacers. Phase 1

Abstract

This report is a Small Business Innovative Research (SBIR) project to study the benefits of ultrasonics and/or new spacers to enhance cleaning fouled reverse osmosis elements. The study shows that the spacers if properly designed can reduce fouling significantly. Ultrasonics have been shown to be feasible as a method of enhancing rapid cleaning especially with the new more effective spacer. Resonating the water is more effective than resonating the construction material. Further research is recommended to develop specific designs to optimize the cleaning process. Keywords: Water treatment; Water filters; Reverse osmosis; DeSalination; Spiralwound configuration membrane process; Water purification; Element cleaning; Ultrasonic cleaning.
