A system and a method for removing solid buildup from a filter media is disclosed. A slurry is passed parallel across a cross-flow filter, the filter comprising a conductive filter media and the slurry comprising a carrier liquid and solids. A portion of the carrier liquid crosses through the filter media as a permeate while a thickened slurry continues parallel to the filter media. A blockage of at least a portion of the filter media is detected. The blockage comprises a portion of the solids. At least a portion of the filter media is heated to a melting temperature of the solids, such that a portion of the blockage melts, whereby the blockage is cleared.
