Reasons for foaming in sewage treatment plants There are several main reasons for foaming in sewage treatment plants: 1. Chemical factors The presence of surfactants Surfactants are one of the common causes of foaming. Domestic sewage contains a large amount of detergent ingredients, such as sodium alkylbenzene sulfonate. The molecular structure of these surfactants is […]
