Treating Industrial Waste Inteferences at Publicly-Owned Treatment Works


  • E.D. Wetzel
  • S.B. Haber

Discharges of heavy metals, toxic organics and variable strength conventional pollutants from industrial (and other nondomestic) sources can have negative impacts on the operation of POTWs. Such discharges can result in an "interference" at a POTW. The book considers the sources of and contaminants causing interference, the impact on the POTW, and the mitigation techniques available for interference prevention.
