A wide variety of contaminants (heavy metals, suspended solids, colloids, oils, organics) have been successfully removed from wastewater using an electrocoagulation process. An innovative electrocoagulation system is described. This process involves a procedure which subjects dissolved and suspended wastewater contaminants to the simultaneous addition of metal ions in the presence of direct current. During the treatment process ionic and other charged particles in the wastewater are neutralized with oppositely charged ions generating the coagulation of contaminants: The process is called CURE, and presented here with application to wastewaters containing mainly heavy metals.
