Electrochemical system and method for the treatment of water and wastewater

A system for removing contaminants from raw water or waste water, the system including at least one electrochemical treatment module comprising:

• a housing having an inlet for untreated water and an outlet for treated water that has been treated within the housing;
• an array of electrodes within the housing, the electrodes having space therebetween of a selected distance, the space being greater than about 0.25 inch (0.635 cm);
• a source for applying direct current the electrodes to charge one portion of the array positively and another portion of the array negatively so as to create an electrical gradient between the portions of the array, the direct current being sufficient to oxidize and to neutralize small particle surface charges in an aqueous solution, and
• container structure adjacent the housing, the container structure having an inlet chamber and an outlet chamber, the inlet chamber accumulating untreated water and delivering the untreated water to the inlet of the housing, an outlet of the housing being connected to the outlet chamber of the container and an outlet line being connected to the outlet chamber to drain away the treated water.
