Ultrasonic defouling of reverse osmosis membranes used to treat wastewater effluents

On-line ultrasonic cleaning was used to remove fouling from a commercially important polyamide based reverse osmosis membrane during cross-flow filtration of CaSO4, Fe3+ and carboxyl cellulose solutions. In each case, the permeate flux of the membrane increased significantly, with virtually no decre...
