Claim:
1. A standpipe arrangement for holding and for supplying gas from aerators in a clarifying basin, comprising: a pipe conduit comprising: a plurality of support pipes having openings; at least one support pipe fastener for fastening at least two of said plurality of support pipes together along a pipe axis wherein said at least one support pipe fastener has a nipple at one end and a sleeve at another end; a plurality of aerators with at least one aerator in communication with at least one of said openings; a holder configured to couple said plurality of aerators to said pipe conduit; and a fastener for fastening said pipe conduit to the clarifying basin; wherein said at least one support pipe fastener is configured to fix said plurality of support pipes both at a distance over the base of the clarifying basin, and also laterally as well as against rotation about the pipe axis, wherein said at least one support pipe fastener is moveable along the pipe axis; at least one base plate having a lower support surface and lateral sides wherein said plurality of support pipes are coupled to said base plate and wherein said base plate is configured to space said plurality of support pipes at a distance from said lower support surface, wherein said at least one base plate is configured to provide a torsional safety of the plurality of support pipes among each other and laterally, and additionally allow said plurality of support pipes to be slidable in an axial direction; wherein said of at least one support pipe fastener engages in a sleeve of an adjacent support pipe of said plurality of support pipes, wherein said at least one support pipe fastener has attachments arranged opposite each other in pairs, and wherein said attachments fix said support pipe axially; wherein said attachments are configured to engage each other after rotating to form an axial positively locking fit between adjacent support pipes of said plurality of support pipes, and wherein the standpipe arrangement further comprises an attachment fastener and a support fitting, said attachment fastener configured to fasten said attachments to said support fitting and wherein said attachments provide lateral fixation relative to the support fitting and allow axial displacement relative to said support fitting.
