MEMBRANE CLEANING WITH PULSED AIRLIFT PUMP

摘要

A method of cleaning a membrane surface immersed in a liquid medium with a
fluid
flow, including the steps of providing a randomly generated intermittent or
pulsed fluid
flow along the membrane surface to dislodge fouling materials therefrom. A
membrane
module is also disclosed comprising a plurality of porous membranes (6) or a
set of
membrane modules (5) and a device (11) for providing a generally randomly
generated,
pulsed fluid flow such that, in use, said fluid flow moves past the surfaces
of said
membranes (6) to dislodge fouling materials therefrom.
