Apparatus for magnetic separation of impurities from fluids |
(57) Disclosed is an apparatus for efficiently effecting a high gradient magnetic separation
process. This apparatus for purifying impurities in fluids provides a plurality of
filter elements with a frame streched with ferromagnetic linear bodies which are contained
in fluid flowpassage in a non-magnetic case, a magnetizing device disposed externally
on side walls of the non-magnetic case, and washing means for washing the filter elements,
whereby magnetic impurities in the fluid can be capatured efficiently, and backwashing
can be easily accomplished.
