Title:
WATER PURIFIER AND CATALYST CARRIER
Document Type and Number:
Japanese Patent JP2019037915
Kind Code:
A
Abstract:
To provide a water purifier that removes arsenic in water using a catalyst carrier 11 that is easy to manage and operate.SOLUTION: A water purifier includes: a catalyst oxidation tank 10 which oxidizes arsenic in water by a catalyst carrier 11; and a crystallization tank 20 in which arsenic is crystallized by a crystallization member 21 on downstream of the catalyst oxidation tank 10. The catalyst carrier 11 is a catalyst resin composition containing powdered iron oxide and powdered carbon, thereby oxidizing and precipitating arsenic into less toxic pentavalent arsenic. The crystallization member 21 contains iron (Fe), thereby forming a complex oxide with arsenic.SELECTED DRAWING: Figure 1
