    Abstract: 1,227,391. Aerating sewage. STENBERGFLYGT A.B. 3 April, 1968 [5 April, 1967], No. 16024/68. Heading C1C. Sewage enters scoop 28 by inlet 26 and tilts the scoop so as to feed regenerated aerated sludge from scoop 29, in regeneration chamber 5, to the mixing chamber 10 via the screen 31. The mixture is aerated by diffuser 12 and then transported by means of air lift 13 to the flocculation chamber 11 where further aeration takes place with diffuser 18 which also prevents sedimentation. The mixture passes via opening 20 to sedimentation chamber. Purified liquid is discharged at 32 while sludge passes through the openings 22 to be lifted by diffuser 23 for return to raw sewage. If the sludge level rises too high it is fed back to sedimentation tank by pipe 25.

    Abstract: A system for purifying sewage water by flocculation and aeration using a buffer chamber, a flocculating chamber, a sedimentation and sludge concentration chamber and a regenerating and sludge activating chamber. The system uses activated sludge as a flocculating agent. The system further comprises a mammoth pump between the buffer and flocculating chambers and another between sedimentation and regenerating chambers. A tiltable bucket regulates the sludge feed to the regenerating chamber permitting a part of the fluid flow to pass by the side. The bucket by means of a valve, further controls a driving air supply to another mammoth pump, the transmitted quantity of activated sludge to the regenerating chamber being thus adjusted to match the quantity of sewage water measured by the bucket.
