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.
A water treatment system comprising:
A method of operating a water treatment system positioned in a tank, the system comprising a membrane module comprising a plurality of hollow fiber membranes, a chamber having a liquid feed inlet and a gas inlet and positioned below the membrane module, the method comprising:
A method of cleaning a membrane surface immersed in a liquid medium comprising:
A method of removing fouling materials from a surface of a plurality of porous hollow fiber membranes mounted and extending longitudinally in an array to form a membrane module, the membranes being arranged in close proximity to one another and mounted to prevent excessive movement therebetween, the method comprising:
