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.
Claims34
An apparatus for water treatment comprising:
- means for removing ingredients contained in water;
- and
- means for adsorbing ions with a porous formed article as an adsorbent, wherein
- the porous formed article comprises a fibril containing an organic polymer resin, and an inorganic ion adsorbing material;
- the fibril forms a three-dimensional network structure;
- the fibril forms communicating pores opening at an outer surface of the article and has inner cavities, each of which cavities opens at the surface of the fibril through at least a part of the each cavity;
- and
- the inorganic ion adsorbing material is supported on the outer surface of the fibril and on the surface of inner cavities of the fibril.
A method of treating water comprising:
- a step of removing ingredients contained in water;
- and
- an ion adsorption treatment step of using a porous formed article as an adsorbent, wherein
- the porous formed article comprises a fibril containing an organic polymer resin, and an inorganic ion adsorbing material;
- the fibril forms a three-dimensional network structure;
- the fibril forms communicating pores opening at an outer surface of the article and has inner cavities, each of which cavities opens at the surface of the fibril through at least a part of the each cavity;
- and
- the inorganic ion adsorbing material is supported on the outer surface of the fibril and on the surface of the inner cavities of the fibril.
