Abstract:
An electrocoagulation process for removing organic, particulate and metal contaminants from a waste fluid to form a clarified waste fluid, comprising the steps of:(a) supplying said waste fluid to a reactor vessel having a plurality of substantially parallel electrolytic plates, said electrolytic plates having a positive or a negative charge provided by a power supply; (b) increasing the pressure of said waste fluid; (c) reacting said charged electrolytic plates with said organic and metal contaminants in said waste fluid to form precipitate particles and dissolved gases that remain in solution in said pressurized waste fluid; (d) reducing the pressure of said waste fluid to release said dissolved gases and to cause said precipitate particles to rise in said vessel; and (e) removing said precipitate particles from said vessel to form said clarified waste fluid.
