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.
