Abstract: There is a standpipe arrangement for holding and for supplying gas to aerators in a clarifying basin. The standpipe arrangement comprises a pipe conduit with holding means for aerators, with gas openings to the aerators and with means of fastening the pipe conduit on the base of the clarifying basin. The pipe conduit comprises several support pipes connected to each other, at the connection points of which fastening means are arranged. By way of the fastening means the support pipes are fixed both at a distance above the base of the clarifying basin as well as laterally and against rotation about the pipe axis, but can be moved along the pipe axis.

Abstract: A gassing device for the intermittent introduction of oxygen-containing gas or air into the waste water of a sewage treatment plant includes at least one membrane and a support body supporting the membrane and having gas-inlet openings. The membrane comprises a support membrane and a gassing membrane, wherein through-openings are arranged in the support membrane and continuous perforation slits are arranged in the gassing membrane and connected to the through-openings of the support membrane, or project into same, or are arranged inside the through-openings. The gassing membrane has a greater elasticity and is softer than the support membrane. The width of the through-openings of the support membrane decrease from the outer side and the gassing membrane projects partially or completely into the through-openings of the support membrane, and has a corresponding negative contour in relation to the through-openings of the support membrane.
