ABSTRACT:
Contaminated aqueous systems can be cleaned using an ultra-filtration system that allows for high recovery yields of the surfactant employed therein for recycle and reuse. The system employs specific nonionic surfactants which remain polar and solvated at the higher operating temperatures of the system. The surfactant/contaminant containing aqueous system is ultra-filtered resulting in the surfactant passing through with the permeate at extremely high yields for recovery and reuse.
