Abstract: A system for filtering fluid that includes a start tank, a finish tank, and a polisher. The polisher includes an inlet, a first outlet fluidly coupled to the finish tank, a second outlet fluidly coupled to the start tank, a filter unit, and one or more transducer coupled to an outer surface of the polisher. The one or more transducers to induce at least one of an electric field or a magnetic field across the filter unit. The start tank is fluidly coupled to the inlet of the polisher.

Abstract: A method of filtering a fluid includes flowing a fluid into a filter assembly. The filter assembly includes a vessel defining a pressure chamber and a filter screen disposed within the vessel. The screen divides the pressure chamber into a first subchamber and a second subchamber. In addition, the method includes flowing the fluid from the first subchamber to the second subchamber, and controlling a first pressure of the first subchamber relative to a second pressure of the second subchamber to induce cavitation in the flowing fluid. Further, the method includes precipitating out dissolved impurities within the fluid during the cavitation.

Abstract: A method of filtering a fluid, including flowing a fluid from a first side of a filter member to a second side of the filter member, the fluid containing dissolved impurities. In addition, the method includes inducing fluid cavitation within the fluid to precipitate out at least a portion of the dissolved impurities. Further, the method includes controlling a pressure differential across the filter member. Still further, the method includes, maintaining or further inducing the fluid cavitation within the fluid in response to controlling the pressure differential. Related systems are also disclosed.
