Abstract
Wastewater 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 wastewater is treated in this manner, the resulting treated water is purified and has a high salt content suitable for oil or gas well injection.
Claims15
A process for treating water containing impurities, the process comprising:
- in a mixing vessel, continuously treating the water with a first oxidizing agent,
- wherein the first oxidizing agent is dispersed into the water in an upper portion of the mixing vessel, and a second oxidizing agent is concurrently dispersed into the water in a lower portion of the mixing vessel;
- continual or cyclic removal of contaminants floating to the top of the mixing vessel and contaminants settling to the bottom of the mixing vessel;
- and
- withdrawing treated water from the mixing vessel.
