Industrial Wastewater Pollution and Advanced Treatment Techniques

Abstract

Industry creates more pressure on water resources by wastewater discharge than the quantity used in production. The wastewater produced by industries may be either excessively acidic or alkaline or may contain high or low concentrations of colored matter, organic or toxic materials, and possibly pathogenic bacteria. It is necessary to pre-treat the wastes prior to release to the sewer or a full treatment is necessary when this is discharged directly to surface or ground waters and it must be within the effluent standard limits provided by the environmental protection organizations. The management and control of liquid wastes in the industry as well as the selection of the different possible treatments for the wastewater prior to its discharge to the sewer system was studied. These would protect the environment and also benefits from the waste materials can be gained. Opportunities for introducing pollution prevention measures for different types of pollutants produced by different industries are discussed in this chapter.
