Patent DE-2647920-B1 (DE)
Title: Sludge activating tank for sewage treatment - has rotating bridge carrying aerating equipment above treatment circuitry
Inventor: SCHREIBER AUGUST DR-ING
IPC: C02F3/12
Filed: 1976-10-22
Abstract: The activating installation consists of a circular settling tank. At the centre of the tank a bearing point is provided on which a ventilating bridge rotates. The bridge extends across the full width of the tanks to the outer wall, and aerating equipment is carried on the bridge sections on each side of the centre point. The drive is located at the outer end of the bridge, which is balanced on the centre bearing so that the load on the running wheels on the circumferential rail is just sufficient for the drive to operate without the wheels slipping. It is possible when the installation is overloaded to feed in a sufficient quantity of oxygen without the use of bottom aerators. Expensive and uneconomic aerators for the bottom of the tanks are unnecessary.
