摘要：
The invention concerns an aerating device for a water filtering system with immersed membranes (9) designed to be installed substantially beneath said membranes (9). The invention is characterized in that it comprises a floor (1) separating an upper chamber wherein said membranes are immersed and a lower chamber comprising means for feeding a liquid to be treated and means for feeding an aerating gas, said floor being provided with plural strainers (2) and with at least one system (5) for balancing pressures between said upper and lower chambers, and in that each strainer (2) includes a substantially tubular element (13) passing through said floor and having in its upper part at least one orifice (4), and an air chamber forming element (3) mounted atop said upper part.
