45、his European Standard specifies the minimum purity requirements for potassium peroxomonosulfate used for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the product. Depending on the raw material and the manufacturing process other impuritie
46、s may be present and, if so, this shall be notified to the user and when necessary to the relevant authorities. Users of this product should check the national regulations in order to clarify whether it is of appropriate purity for treatment of water intended for human consumption, taking into accou
47、nt raw water quality, required dosage, contents of other impurities and additives used in the product not stated in the product standard. Limits have been given for impurities and chemicals parameters where these are likely to be present in significant quantities from the current production process
48、and raw materials. If the production process or raw materials leads to significant quantities of impurities, by-products or additives being present, this shall be notified to the user. 4.2 Composition of commercial product The commercial product shall contain KHSO5(potassium peroxomonosulfate) at a
49、mass fraction greater than 45 percent or the manufacturers declared values.
