<p>A method and apparatus for pressure aeration of biodegradable waste material to enhance the rate of degradation by aerobic bacteria. The method involves pressure aeration while in a turbulent state, followed by introduction to a mixing and separating zone, the mixing portion of Said zone being separated from the separating portion of said zone by a back pressure creating means, the separating portion of said zone having a gas outlet through which undissolved gases and lqiuid are discharged and a treated waste material outlet through which aerated or treated waste material is discharged. The method and apparatus achieve 70 to 80 percent oxygen saturation of the waste material in from a fraction of a second up to a few seconds.</p> |
