Aerating system for liquids, and especially waste water for treating sewage, has an elastic bush at mounting of aerating element at distribution pipe to compensate for flow forces

摘要

An assembly to aerate liquids, and especially water, has a bush with elastic distortion between the distribution pipe and the aerating element of rubber or similar material. The bush is fitted into a drilling in the wall of the distribution pipe, with a flat section at one side at the distribution pipe, and the other side lies at the end side of the aerating element. An assembly to aerate liquids, and especially water, has a bush (12) with elastic distortion between the distribution pipe (1) and the aerating element (2,3), of rubber or similar material. The bush is fitted into a drilling (15) in the wall of the distribution pipe, with a flat section (16) at one side at the distribution pipe, and the other side lies at the end side (7) of the aerating element. A hollow bolt (13) is firmly bonded to the aerating element.
