ABSTRACT:
A screen main body extends in a vessel of desalting-filtration device to section the interior of the vessel into an upper chamber in communication with an inlet through which a liquid to be treated is charged into the vessel and a lower chamber in communication with a liquid outlet. An ion-exchange filtration layer is disposed between the screen main body and the liquid outlet. Ferromagnetic filter elements which form a magnetic filtration layer when magnetized are piled on the screen main body such that the surface of the piled filter elements becomes free. Magnet insertion tubes made of a non-magnetic material vertically extend through the screen main body and a permanent magnet is vertically movably inserted into each magnet insertion tube so that when the permanent magnet is inserted into the magnet insertion tube, the filter elements surrounding the magnet insertion tube are magnetized; but when the permanent magnet is pulled out of the magnet insertion tube, the filter elements are de-magnetized.
