WATER TREATMENT SYSTEMS WITH DUAL PURPOSE ION EXCHANGE RESIN

摘要

A low pressure point-of-use water treatment system may generally comprise at least one inlet port (20) in fluid communication with at least one outlet port (30) to define a fluid pathway therethrough (40); an iodinated resin (50) intermediate the at least one inlet port (20) and the at least one outlet port (30), wherein the iodinated resin (50) transfers iodine into the fluid pathway (40) for a volume of water corresponding to an effective life of the iodinated resin (50); and an ion exchange resin (60) intermediate the iodinated resin (50) and the at least one outlet port, wherein the ion exchange resin removes at least a portion of the iodine transferred by the iodinated resin into the fluid pathway for a volume of water corresponding to a breakthrough point as measured by iodide leakage; and wherein the ion exchange resin inactivates contaminants in the fluid pathway as the iodinated resin nears the end of its effective life.
