Question

Sources and characteristics of industrial waste water and sewage

Answer 1

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.

Most industries produce some wastewater. Recent trends have been to minimise such production or to recycle treated wastewater within the production process.
