= Pretreatment (Industrial Wastewater) = Pretreatment is the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater before or in lieu of discharging, or otherwise introducing such pollutants into a Wastewater Treatment Plant (WWTP). Pretreatment is generally used for industrial wastewater rather than domestic sewage. This is because industrial wastewater contains nonconventional pollutants that WWTPs are unable to treat. The main goal of pretreatment is to prevent interference or pass through at the WWTP, or to cause harm to the WWTP workers or damage to the plant itself.
