Improved methods and processes for iodine disinfection

摘要

Described is a purification process using iodine for decontamination. The process comprises a source of water for one or more water consuming applications and providing a water stream in the process, a delivery station located between the source of water and a treatment station, a source of iodine at the delivery station and means to enable release into the water stream of iodine, means for recovery of the iodine and/or iodide and/or other iodine species derived from the iodine from the water stream; and means for conversion of all the recovered iodine species derived from the iodine delivered to the stream to iodine as used in this system. The iodine in the water stream is maintained at a predetermined concentration to provide a predetermined level of purification of the water stream and/or objects in contact with the water stream in the treatment station; wherein the predetermined concentration is maintained using a monitoring electrode associated with the delivery station in the water stream.
