Abstract
Filtration systems and methods for removing a filter residue from a filter employed in filtering a liquid (for example, grey water). The filtration system may include a vessel having an inlet through which a liquid can be introduced during use and an outlet through which filtered clean liquid can exit. A filter configured to filter the liquid is disposed within the vessel between the inlet and the outlet. The filtration system may further include at least one transducer disposed on or adjacent to the filter. The at least one transducer may be configured to generate one or more pressure waves effective to dislodge at least some residue materials collected on an upstream side of the filter.
Claims30
A filtration system for filtering solids from a liquid, the filtration system comprising:
- a vessel including an inlet through which liquid can be introduced during use and an outlet through which filtered liquid can exit;
- a filter disposable within the vessel between the inlet and outlet, the filter configured to filter the liquid;
- at least one transducer disposed in, on or adjacent to the filter, the at least one transducer being configured to generate one or more pressure waves effective to dislodge at least some residue from the filter.

A filter module for use in a filtration system for filtering solids from a liquid, the filter module comprising:
- a plurality of hollow fiber membrane filters, each of the plurality of hollow fiber membrane filters configured to filter a liquid;
- and
- at least one transducer disposed in, on, or adjacent to the plurality of hollow fiber membrane filters, the at least one transducer configured to generate one or more pressure waves effective to dislodge at least some residue from the plurality of hollow fiber filters.
-43. (canceled)
A method for removing at least some residue from a filter used in filtering a liquid, the method comprising:
- generating at least one pressure wave within a liquid at a location in, on, or adjacent to a filter having the at least some residue disposed thereon to be removed, the generated pressure wave dislodging at least some residue from the filter that would otherwise reduce performance of the filter.
