Yes, soap water and detergent can be treated by microbes in sewage treatment. Soap contains organic compounds like fatty acids and oils which can undergo complete biodegradation by specially selected bacteria.

Comparatively detergents are recalcitrant in nature but ammonia, phosphorus, and phenol compounds in detergent can be treated by specialized bacteria available in Cleanmaxx STP.
