A method and apparatus for achieving high quality treatment of organic waste water (both domestic and industrial types), which can also be used to treat organically contaminated water supplies or to reduce hazardous organic wastes (cyanides, PCBs, etc.) The apparatus operates at elevated pressures (up to about 35 psig), at high levels of dissolved oxygen (over 5 PPM), and at high concentrations of activated sludge (about 10,000 mg/l, MLSS). It consists of four separate process compartments (2 aeration compartments, a separator and a clarifier) which are contained within three vessels or alternatively in two vessels. The process compartments are linked in series by passageways and by piping and are maintained at a uniform pressure using a common manifold. The process is designed for simplicity of operation, compactness, and maintenance by a single part time attendant.
