  • Method of and apparatus for the biological decontamination of waste water
    Patent number: 4442005
    Abstract: A substantially constant loading waste water treatment process and apparatus subjects the waste water to treatment with recycled sludge and oxygen in an activation basin. The suspension is separated into sludge and effluent and a portion of the recycled sludge, when the waste loading exceeds a threshold value, is aerated before being introduced into the activation basin in a separate aerating basin.

  • Control of sludge temperature in autothermal sludge digestion
    Patent number: 4276174
    Abstract: A process for controlling the autothermal aerobic digestion of sludge wherein sludge is mixed with an oxygen-containing gas in a covered digestion zone to form an aerated mixed liquor. The oxygen-containing gas is introduced into the mixed liquor being aerated at an oxygen concentration of at least 20% by volume, in sufficient quantity and rate to dissolve at least 0.03 pounds of oxygen per pound of total volatile solid content in the sludge introduced into the covered aerobic digestion zone, and the volatile solids content of the aerated mixed liquor is maintained at a high level.
