Due to the large volumes of water used in pulp and paper processes, virtually all U.S. mills have primary and secondary wastewater treatment systems to remove particulates and BOD. These systems also provide significant removals (e.g., 30 to 70%) of other important parameters such as AOX and chemical oxygen demand (COD). [Pg.873]

Industrial effluents tend to be complex and vary significantly from one industry to another consequently they must be treated on a case-by-case basis [40]. The potential impact of industrial effluents when discharged to sewer is assessed primarily by measurement of volume, COD (chemical oxygen demand) and suspended solids. Consents, or effluent standards, are normally issued by regulators for discharge to sewer [41 ], and these include limits on volume, COD, suspended solids and specific pollutant types, for example heavy metals, grease and oil, persistent and/or toxic organics and colour from waste dyes. [Pg.161]
