摘要： An apertured flexible membrane (10) extends over a domed support (11). A central gas supply tube (50, 82) terminates in gas outlets (51) oriented to direct the gas to flow horizontally into the space (40) between the membrane and the support to inflate the membrane away from the support so that gas from the inflated space discharges through the apertures (60) as fine bubbles and such that when the gas supply ceases the membrane collapses back into area contact with the support to seal all the apertures. This reduces clogging. The aerator is useful in the aeration of sewage or waste water and in fish or eel farms.

摘要： A microporous flow control element having a non-labyrinthine, accurately controlled pore size is provided by a helically coiled wire with contacting coils of cross-section reducing inwardly from an outer face so as to define contact edges one of which is provided with microscopic grooves closed by the adjacent coil edge. The wire may be a tension coil spring whereof the coils are held in close contact by the spring force.

摘要： PCT No. PCT/DE87/00273 Sec. 371 Date Feb. 6, 1989 Sec. 102(e) Date Feb. 6, 1989 PCT Filed Jun. 12, 1987 PCT Pub. No. WO87/07590 PCT Pub. Date Dec. 17, 1987.In a method and a device for the widespread fine-bubble aeration of liquids, resilient, perforated membranes, which are preferably in the form of aeration hoses, are arranged in a liquid receptacle and are maintained horizontal by means of holding and guiding devices and are stretched, relative to their rest states, preferably by means of tensioning devices. Because of the stretching, the passage of the gas is improved and a uniform, finely dispersed gas bubble formation is produced. For clearing the perforated membranes of blockages of the perforations, the streteched state of the membranes is briefly released and subsequently again reproduced. For strong impurities, the gas supply is interrupted, the membranes are exhausted of gas and water, the stretched state is subsequently released and, after a predetermined time, gas is again fed into the perforated membranes and then the stretched state is reproduced.

摘要： Ce procédé et ce dispositif concernent le traitement des eaux usées (4) respectivement des boues d'égout. Pour l'obtention d'un traitement efficace des eaux usées dans un unique bassin de boues activées (2) un élément d'introduction de gaz (9) pour la préparation des eaux usées (4) est soulevé verticalement dans la direction de la surface supérieure des eaux, respectivement au-dessus de celle-ci. Ce ce fait la sortie des gaz qui jusque-là pendant la phase d'introduction de gaz se faisait de préférence sous forme de bulles microscopiques est largement réduite, respectivement complètement inhibée.
