Aluminium chloride, aluminium chloride hydroxide and aluminium chloride hydroxide sulfate (monomeric) are acidic
liquids which hydrolyse and form a precipitate of aluminium hydroxide when diluted beyond a particular level.
NOTE 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.
4 Purity criteria
4.1 General
This document specifies the minimum purity requirements for aluminium chloride (monomeric), aluminium chloride
hydroxide (monomeric) and aluminium chloride hydroxide sulfate (monomeric) used for the treatment of water
intended for human consumption. Limits are given for impurities commonly present in the product. Depending on
the raw materiel 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 chemicals 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.
