Abstract:
A method of decontaminating water from a source to provide potable water comprising:a. providing water to be decontaminated from a water supply at a volumetric flow rate;b. directing the water through a disinfecting section by:i. directing the water through a polyiodinate resin to add iodine disinfectant throughout said water, the iodine disinfectant added to the water having a minimum disinfecting time during which a desired level of disinfection can be accomplished;ii. directing the water from the disinfectant section through a retention means by directing the water through an elongate residence tube, said tube having a travel length through which the water travels during a residence time in the tube that is dependent on volumetric flow rate through the tube;c. said process further comprising matching the volumetric flow rate of the water from the water supply with the travel length of the tube so that a residence time of any segment water passing through the tube is at least as great as the disinfecting time, to accomplish decontamination of the water;d. directing the water through a predisinfectant filter section prior to the disinfecting section, wherein said predisinfectant filter section comprises a cyst filter to remove cysts from the water prior to the water passing through the disinfecting section, and directing the water through a post disinfection filter section to remove objectionable material from the water after passing through the tube;e. the water in said process being entirely directed through said injection, said tube and said filter section which are all in series so that potable water is produced.
