Abstract
A system and apparatus for disinfecting sewage water and removing suspended solids therefrom by in-situ treatment with chemical agents and gases, each produced electrolytically, comprising a treatment chamber, disinfecting and solids conveying means including at least one pair of electrodes disposed in the chamber, solids removal means associated with the chamber, a source of aqueous alkali metal halide solution and optionally an ultraviolet light ray source and solids collection means.
Claims2
The process for treating sewage water which comprises:
- A. providing a sewage-containing alkali metal halide solution to an upwardly tapered cell chamber ending in a solids discharge outlet and having submerged dimensionally stable electrodes disposed therein;
- B. agitating and disintegrating solids contained in said solution;
- C. passing a direct electrolyzing current between opposed dimensionally stable anodes and cathodes in said solution, whereby said solution and solids are disinfected and said solids float to the top of the chamber;
- D. removing solids and entrained solution through the solids discharge outlet;
- and
- E. discharging treated solution from said chamber.
