A method of cleaning water systems and an oxidizer (e.g., a potassium monopersulfate composition) that is used for the method are presented. When potassium monopersulfate is used as the oxidizer, it preferably has a low concentration (<0.5 wt. %) of potassium oxodisulfate byproduct that causes irritation. The low potassium oxodisulfate concentration allows the composition to be used more liberally than conventional potassium monopersulfate. To control the release rate of the oxidizer, the oxidizer is formed into a tablet and coated with a material that dissolves at a desired rate. The coating material controls the rate at which the oxidizer is released when placed in contact with a solvent. The coated tablets may be aggregated under high pressure to form an agglomerate composition. A binder and/or a filler material may be added when forming the agglomerate composition to achieve a desired oxidizer release rate.
提出了一种清洁
水系统的方法和用于该方法的氧化剂(例如,一种过
硫酸钾组合物)。当过
硫酸钾被用作氧化剂时,最好具有低浓度(<0.5重量%)的氧化钾二硫酸盐副产物,因为这会引起刺激。低氧化钾二硫酸盐浓度使得该组合物可以比传统的过硫酸
钾更加自由地使用。为了控制氧化剂的释放速率,氧化剂被制成片剂,并涂覆有以所需速率溶解的材料。涂覆材料控制了氧化剂在与溶剂接触时释放的速率。涂覆的片剂可以在高压下聚集以形成一种聚集物组合物。当形成聚集物组合物时,可以添加粘合剂和/或填料材料以实现所需的氧化剂释放速率。
