1. A method of filtering a fluid, the method comprising:
receiving a flux solution in a feed tank;
introducing an oxidizer into the flux solution in the feed tank;
forming a precipitate in the flux solution within the feed tank in response to introducing the oxidizer;
passing the flux solution with the precipitate to a filtering vessel containing a filter comprising a filter media;
receiving the flux solution with the precipitate in the filter from a first direction;
flexing a portion of the filter media inward into the space based on receipt of the flux solution with the precipitate;
accumulating a filter cake on the filter media in response to receiving the flux solution in the filter from the first direction;
receiving a gas in the filter from a second direction opposite to the first direction;
flexing the portion of the filter media outwards from the space upon receipt of the gas; and
removing the filter cake from the filter media based on flexing the portion of the filter media outwards.
