ABSTRACT:
A method of removing soluble and insoluble small particle size materials from wastewater by binding the small particle size material with a combining agent to form soluble and/or insoluble bound materials having a particle size sufficiently large to permit filtration of the wastewater with removal of the bound materials. The method is preferably carried out to remove heavy metals and other materials from metal plating and finishing wastewater to allow recovery and reuse of the water in plating and finishing operations and/or permit recovery and salvaging of the metals normally carried by the wastewater.
