Abstract A method and a mixture of complexes for removing both organic matter and bacteria from bodies of water, such as those confined in swimming pools and similar vessels characterized by filter systems including filter mediums for separating solids from flowing pool water. The method is characterized by introducing into a filter system, immediately upstream from the employed filter medium, a mixture of complexes including cuprous iodide and copper carbonate for thereby coating the filter medium with a layer of substantially water insoluble source of copper ions and elemental iodine, and subsequently adding to the pool, downstream from the filter medium, an oxidant selected from a class of oxidants including chlorine for releasing elemental iodine from the cuprous iodide for thus rendering the pool pleasing in appearance and safe and pleasant to bathers.
IN A METHOD OF TREATING A BODY OF WATER SUBSTANTIALLY CONFINED IN A SWIMMING POOL WITH IODINE, THE IMPROVEMENT COMPRISING THE STEPS OF: INTRODUCING INTO A SELECTED BODY OF WATER SUBSTANTIALLY CONFINED IN A SWIMMING POOL, UPSTREAM OF THE FILTER MEDIUM FOR A FILTRATION SYSTEM PROVIDED FOR THE POOL, A SUITABLE QUANTITY OF A MIXTURE OF COMPLEXES INCLUDING SUBSTANTIALLY EQUAL PARTS BY WEIGHT OF CUPROUS IODIDE AND COPPER CARBONATE FOR ESTABLISHING IN THE BODY OF WATER A CONCENTRATION OF COPPER IONS ABOVE 0.015 PARTS PER MILLION BUT LESS THAN 2.0 PARTS PER MILLION COPPER IONS AND ADDING TO THE BODY OF WATER A SUFFICIENT QUANTITY OF AN OXIDANT SELECTED FROM A CLASS OF OXIDANTS, INCLUDING CHLORINE, FOR CAUSING ELEMENTAL IODINE TO BE RELEASED FROM THE CUPROUS IODIDE INQUANTITIES SUFFICIENT FOR MAINTAINING IN SOLUTION IN SAID BODY A CONCENTRATION OF FREE IODINE ABOVE 0.1 PARTS PER MILLION BUT LESS THAN 5.0 PARTS PER MILLION, WHEREBY FREE IODINE IS SLOWLY RELEASED FROM THE CUPROUS IODIDE IN THE PRESENCE OF CHLORINE UNATTENDED BY DISCOLORATION OF THE WATER FOR THUS RENDERING THE BODY OF WATER SAFE AND PLEASING IN APPEARANCE.
