A chemical composition for use in purifying water used in swimming pools having surfaces that are comprised of materials that do not react with or dissolve in water, comprising for 2.5 kg of the chemical composition, 1.25 kg of potassiumpersulphate, 300 g of sodium bisulfate, 250 g of ammonium chloride, 100 g of aluminum sulfate, 250 g of sodium bicarbonate, 250 g of calcium chloride and 100 g of ethylendiamine tetra acetic acid (abbreviated EDTA). The potassiumpersulfate and the ammonium chloride are effective in disinfecting water to be purified and in eradicating algae and bacteria therein. The sodium bisulfate, sodium bicarbonate and the calcium chloride are effective in balancing the pH of water to be purified to a pH value within an optimum range between 7.2 and 7.6. The aluminum sulfate serves as a flocculation aid and the copper sulfate is effective in the eradication of black algae. The EDTA is effective to complexing heavy metals in the water.
A chemical composition for the purification of water for use in non-porous swimming pools, which comprises a primary mixture of a peroxide compound in the form of an alkaline persulphate, an acidic compound in the form of sodium bisulphate, an ammonium-based biocidal compound, a basic compound in the form of sodium bicarbonate, a calcium-releasing basic compound and ethylendiamine tetra acetic acid (abbreviated EDTA), the mixture containing 45 to 55% (m/m) alkaline persulphate, 8 to 16% (m/m) sodium bisulphate, 8 to 12% (m/m) ammonium-based biocidal compound, 8 to 12% (m/m) sodium bicarbonate, 8 to 12% (m/m) calcium-releasing basic compound, and 2 to 6% (m/m) EDTA, the alkaline persulphate and the biocidal compound being effective in disinfecting water to be purified and in eradicating algae and bacteria therein, with the sodium bisulphate, the sodium bicarbonate and the calcium-releasing basic compound being effective in balancing the pH of water to be purified to a pH value within an optimum range between 7.2 and 7.6, and the EDTA being effective to complex heavy metals in the water to be purified.
A kit for the purification of water, for use in non-porous swimming pools, which comprises a primary mixture of a peroxide compound in the form of an alkaline persulphate, an acidic compound in the form of sodium bisulphate, an ammonium-based biocidal compound, a basic compound in the form of sodium bicarbonate, a calcium-releasing basic compound, and ethylendiamine tetra acetic acid (abbreviated EDTA), the mixture containing 45 to 55% (m/m) alkaline persulphate, 8 to 16% (m/m) sodium bisulphate, 8 to 12% (m/m) ammonium-based biocidal compound, 8 to 12% (m/m) sodium bicarbonate, 8 to 12% (m/m) calcium-releasing basic compound, and 2 to 6% (m/m) EDTA, the alkaline persulphate and the biocidal compound being effective in disinfecting water to be purified and in eradicating algae and bacteria therein, with the sodium bisulphate, the sodium bicarbonate and the calcium-releasing basic compound being effective in balancing the pH of water to be purified to a pH value within an optimum range between 7.2 and 7.6, and the EDTA being effective to complex heavy metals in water to be purified.
