Population and production are two major criterias which increases water use, from their increases the wastewater quantity. This increased water use and process wastewater generation requires more efficient removal of by-products and pollutants that allows for effluent discharge within established environmental regulatory limits.

The identification of wastewater testing set forth in environmental permits has been established since the 1970s in a series of laboratory tests focused on four major categories.Those are organics testing, Solid testing, nutritient testing, Physical Properties and Other Impact Parameters.
