WATER TREATMENT APPARATUS FOR PRODUCING REFINED WATER FOR HEMODIALYSIS RECEPTACLE

摘要

PROBLEM TO BE SOLVED: To provide a water treatment apparatus capable of satisfactorily removing endotoxin from raw water and lowering a remaining concentration thereof to the minimum limit.;SOLUTION: Two magnetic treatment devices 7a, 7b are mounted from the outside in the middle of a supply piping 6a from the raw water tank 1 to a pretreatment part 2, a piping 6f for circulation is allowed to branch from between the two magnetic treatment devices 7a, 7b and is returned to the raw water tank 1 and a supply piping 6b is connected so as to supply treated water of the pretreatment part 2 to a softening tank 3. A magnetic treatment device 7c is mounted from the outside in the middle of a supply piping 6c from the softening tank 3 to a reverse osmosis processing part 4, a piping 6h for circulation is allowed to branch from the proximate downstream part of the magnetic treatment device 7c and is returned to the softening tank 3 and reverse osmosis processed water (refined water) of the reverse osmosis processing part 4 is supplied to a refined water tank 5 through a supply piping 6e. Repeated magnetic operations are imparted by the magnetic treatment devices 7a, 7b, 7c, endotoxin in the treated water are aggregated and filtration separation is facilitated.;COPYRIGHT: (C)2005,JPO&NCIPI
