ABSTRACT:
An activated sludge sewage treatment process which includes a mixed liquor tank and a pressure vessel much smaller in size than said mixed liquor tank. At least a portion of the influent to said tank is directed to the pressure vessel where oxygen is dissolved therein under superatmospheric pressures. The pressure is then released and said portion of the influent gently transferred into said mixed liquor tank so that substantially all of the dissolved oxygen remains in solution until said influent portion is mixed with the sewage in the mixed liquor tank to thereby raise the dissolved oxygen concentration in the tank.
