  • Why is aluminium sulphate used in water treatment?
  • Water treatment using aluminium sulphate (VI) generally increases the percentage of dissolved, low molecular weight, polyaluminium species that are chemically reactive and possibly more readily absorbed [ 4 ]. Aluminium has been found in the brain of Alzheimer’s patients in the amyloid deposits characteristic of this disease.
  • What is the water soluble content of aluminium sulphate?
  • 2.2.2 Liquid aluminium sulphate shall contain water-soluble aluminium of not less than 4.23% w/w as Al or 8.0% w/w as Al2O3. 2.2.3 In lump, ground or flaked aluminium sulphate, the water-insoluble matter shall not exceed 0.5% w/w. 2.2.4 In liquid aluminium sulphate, the water-insoluble matter shall not exceed 0.2% w/w.
  • What is alum sulphate?
  • 1.9.1 Alum: Alum also refers to aluminium sulphate. 1.9.2 Aluminium Sulphate: The product of the reaction between sulphuric acid and aluminium trihydrate, with the general formula Al2(SO4)3.14H2O, but note that the number of waters of crystallisation is only approximate; commercial grades can vary from about 13.9-14.5H20.
  • Can I copy the Alum sulphate standard?
  • No part of this Standard may be reproduced, stored in any retrieval system, or copied in any way, without the prior written permission of NZWWA. This Standard covers aluminium sulphate (commonly called alum) in liquid, ground, lump, kibbled or flake form, for use in the treatment of water supplies.
