Abstract
Disclosed is an improved method for oxygenation of liquid waste. The method comprises drawing a low pressure stream of liquid waste from a liquid waste tank and introducing an oxygen-containing gas thereto to provide a mixture of liquid waste and gas. Thereafter, the mixture is pumped into a high pressure stream wherein the pressure is maintained in the range of 50 to 1000 psig to obtain an oxygen enriched dispersion. The oxygen enriched dispersion is then discharged into the holding tank.
