Title: Carrier for water treatment, its production method, and apparatus for water treatment
Inventor: KOYOU HIROYUKI
IPC: C02F3/34
Filed: 2000-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a carrier for water treatment which is resistant to the adhesion of bubbles, has good fluidity etc., and can improve the efficiency of water treatment, a method for producing the carrier, and an apparatus for water treatment using the carrier. SOLUTION: The surface of the carrier is formed from a skin layer, and the inside of the carrier is made porous. By the skin layer, for example, when the carrier is used for a fluidized bed, the surface is resistant to the adhesion of fine bubbles generated in a tank or the direct adhesion of a gas generated by adherent microorganisms, preventing the lowering of its fluidity caused by excess buoyancy given by the adhesion. Since the inside of the carrier is porous, by selecting the porosity appropriately, the specific gravity of the carrier is adjusted to improve its fluidity.
