EN 883:2004 (E) 8 3.4 Chemical properties Polyaluminium chloride hydroxide and polyaluminium chloride hydroxide sulfate are acidic liquids which hydrolyze and form a precipitate of aluminium hydroxide when diluted beyond a particular level. NOTE 1
Since aluminium compounds are amphoteric in nature, the solubility of aluminium depends on the pH value and the products should be used within an appropriate pH range. NOTE 2 A characteristic of these products is their high tendency to hydrolyze which restricts their use; this tendency results from the particular oligomeric or polymeric composition. These products vary in their relative basicity (mole ratio OH/3Al), the percentage of chloride and sulfate ions present and in their method of manufacture. NOTE 3 These variations may affect their performance in the water treatment plant. Special water plant requirements regarding, but not limited to, such items as: organic matter removal, residual aluminium levels and working pH values should be specified when possible, so that the product which best fits the need can be offered. 4 Purity criteria 4.1 General
This document specifies the minimum purity requirements for polyaluminium chloride hydroxide and polyaluminium chloride hydroxide sulfate 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 impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities. NOTE Users of these products 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 account raw water quality, required dosage, contents of other impurities and additives used in the products not stated in this document. Limits have been given for impurities and chemical parameters where these are likely to be present in significant quantities from the current production process and raw materials. If the production process or raw materials lead 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 concentration of active matter (aluminium ion content) in the commercial product expressed as grams per kilogram of product shall be within ± 3 % of the manufacturer's declared values. NOTE The concentration of water- soluble aluminium in commercial products varies. Typical values of aluminium content in the products can be between 42 g/kg and 124 g/kg. The commercial products vary in the proportions of chloride and sulfate ions. The relative basicity of the polyaluminium chloride hydroxide and polyaluminium chloride hydroxide sulfate, expressed as the mole ratio OH/3Al, shall be greater than 0,35. SIST EN 883:
