Abstract
Apparatus for augmenting or facilitating flushing of impurities collected by a porous ferromagnetic matrix. The matrix is contained in a canister, through which an aqueous clay slurry is flowed as an applied field magnetizes the matrix to enable attraction of the discoloring magnetics. The periodic flushing of the matrix is rendered of increased efficacy, by applying auxiliary mechanical forces to dislodge the magnetics; or other disclosed means and methods may be used to facilitate the flushing operation.
