Abstract

Wastewater treatment process in which organic impurities such as oil, organic brighteners, and chlorinated solvents are removed from the upper surface of wastewater from an industrial process and metal values are precipitated and withdrawn from the wastewater. The remaining clear liquid containing dissolved salts is used to generate working steam in a boiler for an industrial purpose. The wastewater is heated in the boiler to produce an aqueous phase having an increased concentration of impurities and a steam component which is used for the industrial purpose and condensed to produce water which is recycled for use in the industrial process and/or boiler. The accumulated impurity component is removed from the boiler periodically or continuously.
