WebAlkalinity is also important during the coagulation process. Coagulants with a low basicity, such as aluminium sulphate (alum), have a tendency to consume more alkalinity than other coagulants and can therefore significantly reduce the pH of the water. This is a problem especially for water supplies with river sources as the WebAug 23, 2024 · The pH scale ranges from 0-14; 7 indicates the neutral point. The normal pH range of drinking water is 6 – 8.5. The pH is mostly a result of natural geological conditions at the site and the type of minerals found in the local rock. The pH can also be affected by acid rain. Water with a pH value less than 7 is acidic and tends to be corrosive.
