SALH / Type A (Granulated)

Aluminum Sulfate type A is an inorganic salt with the molecular formula Al₂(SO4)3 14.3H20. It is used as a coagulant/flocculant in wastewater treatment and for human consumption. In the acid process of paper manufacturing, it is used to precipitate rosin and maintain a suitable pH. In both fields, water treatment and papermaking, optimal results are achieved at a very low cost. Furthermore, our product complies with international standards for chemical products used in water treatment ANSI/AWWA B 403-09 and NSF.

Dosing / Dissolution

Aluminum Sulfate (SALH) type A is a salt that is easily soluble in water, solutions with concentrations of solid sulfate up to 55% can be prepared. For water treatment, it is suggested that the concentration does not exceed 5% of solid aluminum sulfate, in order to achieve a good dissolution rate. The residence time in the tank where the material is dissolved must not be less than 2.5 min. The maximum dose is 150 mg/L and residual aluminum in drinking water should not exceed 0.2 mg/L.

    Metals of Toxicological Concern

    In regard to impurities, the Venezuelan Standard COVENIN 1350-2006 establishes the following: "Aluminum sulfate should not contribute more than 10% of the maximum value allowed in the current national health standards for drinking water quality". Thus, for a maximum dose of 150 mg/liter of aluminum sulfate, there are the specifications shown in the following table vs. the typical values of the impurities in the product.
