摘要： An apparatus for aerating water, including rigid supporting pipes, which serve to supply air, and covers which are disposed on the supporting pipes close thereto and are provided with a plurality of resiliently expandable slits. The supporting pipes, together with their covers, are disposed virtually in a vertical plane one above the other in a horizontal parallel position. The covers and/or the supporting pipes have air supply openings of different sizes such that these openings, when viewed from bottom to top, become gradually smaller in order to ensure that, when the air supply means is common to all of the supporting pipes and covers of an apparatus, the air throughput quantities are at least substantially identical in size at the different vertical positions of the supporting pipes and covers.
