Abstract (en)

[origin: NZ500570A] A method and apparatus for producing bacteria-free iodine-species-containing drinking water for farm animals under continuous dynamic water flow, comprising dissolving solid iodine into a first water flow to produce a saturated iodine species-containing aqueous solution at a pre-selected temperature; blending the saturated solution with a second water flow to produce a diluted iodine species bacterium-free aqueous solution; and providing the diluted solution as drinking water to the animals. Preferably, the iodine is dissolved in the first water flow (16) to provide a saturated iodine species at a pre-selected temperature at a known concentration, which saturated solution is then blended into a mean water flow (14). The continuous flow of iodine species-containing water is fed to a farm animal drinking water distribution network (50) with reduced risk of back-contamination by bacteria-containing water through the network. Other uses of the iodinated water are as a disinfectant, for example, in the food processing industry; fruit, vegetable and, particularly, as iodinated ice for fish and fish products preservation; industrial, commercial cooling tower waters, sewage and wastewater treatment; and as a nutrient as an iodine source for humans, livestock, fish and plants.
