摘要
The invention is directed to a process for cleaning a submerged filtration membrane in a tank containing a liquid, comprising providing a) a gas-dispersing device, the gas-dispersing device comprising a channel with a circumferential wall with a number of apertures and at least a first inlet and a second inlet; b) providing a pulsed gas flow to the first inlet, or to the second inlet or to both first and second inlets of the gas-dispersing device. The invention is further directed to a gas flow system for this process and a membrane filtration tank with membranes and such gas flow systems.
