Abstract:
A method of electrocoagulation treatment of a liquid comprising the steps of:providing a reaction chamber; arranging a plurality of reaction plates within said reaction chamber, the plates being vertically disposed therein and spaced apart from one another creating gaps between adjacent reaction plates; applying a constant direct current line voltage to selected ones of the plurality of reaction plates to create an electrical field within the reaction chamber; passing a liquid stream vertically through the reaction chamber in the gaps between the reaction plates said reaction plates having consumable surfaces for direct contact with said flow of liquid; adjusting the voltage and amperage between the reaction plates by changing electrical connections between selected ones of the reaction plates and the constant line voltage, said adjusting step further including attaching and reattaching electrical leads directly to said plurality of reaction plates; and conducting electrocoagulation of the liquid stream to cause the reaction plates to give up ions whereby the reaction plates are consumed over time and which cause impurities to coagulate in the liquid stream.
