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 () or a set of membrane modules () and a device () for providing a generally randomly generated, pulsed fluid flow such that, in use, said fluid flow moves past the surfaces of said membranes () to dislodge fouling materials therefrom.

Membrane cleaning with pulsed airlift pump

Disclosed herein are aspects and embodiments of an apparatus for providing gas slugs in a liquid. In one example, the apparatus comprises a housing defining a chamber, a bell tube including a wall and an open upper end disposed within the chamber, a riser tube including a wall, an open lower end, and a flared open upper end disposed within the bell tube, and a conduit defined between the wall of the bell tube and the wall of the riser tube and in fluid communication with an internal volume of the riser tube.

Gas sparging device

Water treatment membrane cleaning with pulsed airlift pump

A method of controlling fouling in a membrane filtration system () of the type where gas is used to clean or scour the membranes () wherein the method includes supplying the gas to the system with a continuously variable flow rate. A continuously variable valve arrangement () is also disclosed.

Continuously variable aeration

A membrane module () including a plurality of porous membranes () extending in an array and mounted, at least at one end, in a header (). The header () has a number of distribution apertures () for distributing a fluid into the module () and along a surface or surfaces of the membranes (). An elongate chamber () having one open end () and another end is in fluid communication with the distribution apertures () for distributing the fluid to the distribution apertures ().

Mixing chamber

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 () or set of membrane modules () and a device () for providing a generally randomly generated, pulsed fluid flow such that, in use, said fluid flow moves past the surfaces of said membranes () to dislodge fouling materials therefrom.

Airlift pump

A membrane module () comprising a plurality of porous hollow membranes (). The membranes () extend between and are fixed at each end in a header (). One header () has one or more of openings () formed therein. The openings () are in fluid communication with a source of gas and/or liquid (). The other of the headers () is sealingly connected to and in fluid communication with a head-piece (). The head-piece () is adapted to couple to an associated head-piece of a further module to form a rack of modules (). A potting head () for use in mounting porous hollow membranes () is also disclosed comprising a preformed potting element (). The potting element () includes one or more cavities () for receiving curate potting material which, in use, supports said membranes ().
