Abstract: A method of cleaning contaminated resins for reuse comprises establishing a countercurrent flow between the contaminated resin and a carrier fluid for carrying the removed contamination from the resin and applying ultrasonic energy to the countercurrent flow with the countercurrent flow being conducted so that a region of turbulence is achieved where the ultrasonic energy is applied. A cleaning apparatus has means for introducing a contaminated resin and means for introducing a carrier fluid to a treatment zone in a countercurrent flow, means for collecting cleaned resin from the treatment zone, means for removing the carrier fluid from the treatment zone, and ultrasonic energy means for applying an ultrasonic energy field to the countercurrent flow in the treatment zone.
