Related Information in Haz-Map
Process Name	Sewer and Wastewater Treatment
Description	Disinfectants used to treat sewage and wastewater include chlorine, chlorine dioxide, ozone, sulfur dioxide, hydrogen peroxide, and 1,3-dichloro-5,5-dimethylhydantoin. Products of decay include hydrogen sulfide, methane, nitrogen, carbon dioxide, and ammonia. Faulty equipment can generate dangerous levels of carbon monoxide. [Sullivan, p. 636-48; ACGIH]
