Abstract

Waste water is remanufactured with ozone in a series of mixing vessels. The ozone is dispersed to both a top and a bottom portion of each mixing vessel, but in different amounts. This creates an electrical potential difference across the height of each mixing vessel which significantly improves the oxidation of organic carbon-based impurities and eliminates H2S and bacteria. Sludge and solids floating to the top of each mixing vessels are removed, as well as sludge and solids settling to the bottom of the mixing vessels. When oil and gas well waste water is treated in this manner, the resulting treated water is purified and has a high salt content suitable for oil or gas well injection.

Dependent claims

A process for treating waste water containing organic impurities, the process comprising:

in a series of mixing vessels, treating the waste water with ozone, wherein ozone is dispersed through inline venturi mixers into waste water entering an upper portion of each mixing vessel, and additional ozone is dispersed into waste water in a lower portion of each mixing vessel;
continual or cyclic removal of the organic impurities as sludge and solid contaminates floating to the top of each mixing vessel and of sludge and solid contaminates settling to the bottom of each mixing vessel;
and
withdrawing treated waste water from a final mixing vessel in the series of mixing vessels, wherein greater than 96% by weight of the organic impurities have been removed.
