  • Apparatus for water treatment and method of treating water
    Patent number: 7967984
    Abstract: An apparatus for water treatment which comprises a means of removing ingredients contained in water and a means of adsorbing ions with a porous molding as an adsorbent, wherein the porous molding comprises fibrils comprising an organic polymer resin and an inorganic ion adsorbent. The fibrils form interconnecting pores open to the outer surface and have voids in inner parts thereof, at least part of the voids being open to the surface of the fibrils. The inorganic ion adsorbent has been deposited on the outer surface of the fibrils and on the surface of the voids in the fibrils.
