ABSTRACT:
The invention pertains to a method and apparatus for processing contaminated water containing high concentrates of volatile and soluble inorganic and organic compounds and ion reaction complexes thereof, and particularly pertains to the removal of high concentrations of hydrogen sulfide from well water, and the invention is well suited for use with domestic water systems. Batches of untreated water are introduced into a vented first holding chamber at a rate and volume related to the removal of batches of treated water from a second holding chamber. The chambers are interconnected by a dilution flow control orifice, or orifices, and air and ozone are mixed with the water within both chambers wherein aeration by air-stripping within the first chamber rapidly reduces the high hydrogen sulfide concentration and the lower hydrogen sulfide content of the water within the second chamber is primarily removed by the ozone. Effective ozonization within the second chamber is assured by stratifying the second chamber water by producing a vortex therein, and the rate of dilution of the water within the first chamber as it is transferred into the second chamber is controlled by the dilution flow control orifice.
