Abstract
A method of cleaning water systems and a potassium monopersulfate composition that is used for the method are presented. Potassium monopersulfate with a low concentration (<0.5 wt. %) of potassium oxodisulfate byproduct is used for the method. Due to the low potassium oxodisulfate concentration, the composition is not subject to stringent usage restrictions that are applied to currently available potassium monopersulfate compositions. Also presented is a polysaccharide coating that can be used to control the rate at which the potassium monopersulfate dissolves upon use. Using the coating, the potassium monopersulfate composition can be used continuously instead of in a periodic shock treatment as is currently done. The low oxodisulfate concentration allows the method to be used regardless of whether the water system is being used by bathers.
