  • Does aluminium sulphate cause acidification of treated water?
  • does not cause acidification of the treated water as aluminium sulphate (VI). The type of hydrolysis type of coagulant. Hydrolysis of alum inium cati ons, which are products of dissociation of non- immediately after their contact with water. As a result, the precipitation of the final hydrolysis in the treated water.
  • Why is the chemical speciation of aluminium in drinking water important?
  • The chemical speciation of aluminium in drinking water is very important, as the form of aluminium regulates its solubility, bioavailability and toxicity. Water treatment using aluminium salts, can increase the percentage of dissolved, low molecular weight aluminium species that are chemically reactive and more readily absorbed by human body.
  • Should aluminium coagulants be controlled in water treatment plants?
  • Aluminium exerts undeniable human health effects, so its concentration should be controlled in water treatment plants. The article presents and discusses the results of studies on the influence of selected properties of aluminium coagulants on the concentration of aluminium remaining in the purified water.
  • Does sodium aluminate coagulate dissolved aluminium?
  • The highest concentrations of residual aluminium and dissolved aluminium were found after coagulation with sodium aluminate ( Figure 3 and Figure 4 a), which undergoes alkaline hydrolysis and increased the pH of treated water in the range from 8.06 to 8.55, creating conditions for the formation of soluble aluminates Al (OH) 4− [ 2, 19 ].
