Abstract:
The disclosure relates to a system and method for cleaning filters, such as membrane filters. More particularly, a method and system are disclosed for retaining a plurality of small particulates, preferably in the shape of beads, which contact sludge or other despots on the membrane filters to remove unwanted debris that would otherwise form on the cleaning filters. In various embodiments, the plurality of small particulates are retained in a permeable enclosure formed of wedgewire.

Claim (Index 1):
A method for cleaning filtration membrane modules, comprising:\n providing at least two removable housing structures, with each of said at least two removable housing structures having a screen that entirely surrounds one or more filtration membranes on all four sides and on top and on bottom, said at least two removable housing structures comprising at least four vertically extending panels on each side of said one or more filtration membranes and a horizontally extending top and a horizontally extending bottom, said removable housing structure, adapted to be positioned within a basin for containing wastewater; positioning said at least two removable housing structures in said basin; flushing the one or more filtration membranes with a liquid containing biologically inert particles; cleaning the filtration membrane modules by circulating the biologically inert particles through the liquid and in a manner to achieve contact between the biologically inert particles and the one or more filtration membranes, said biologically inert particles impacting both sides of said one or more filtration membranes simultaneously during said circulating step; wherein deposits situated on one or more surfaces of the one or more filtration membranes are mechanically abraded by the biologically inert particles, and wherein the biologically inert particles are of a size able to be retained within the at least two removable housing structures; wherein during said circulating step, said biologically inert particles impact each of the four sides and top and bottom of the at least two removable housing structures, and wherein said screen has openings that permit fluid to flow therethrough, said at least two removable housing structures being devoid of any opening through which said biologically inert particles can escape during said circulating step; and wherein said at least two removable housing structures operate as a containment module that prevents said plurality of biologically inert particles from being lost to the environment outside to said at least two removable housing structures.
