WebAlum (aluminium sulphate) is the most commonly used coagulant in Australian water treatment plants, low cost being its major attraction. Alum however, has a number of disadvantages: ♦ limited coagulation pH range: 5.5 to 6.5, ♦ supplemental addition of alkalinity to the raw water is often required to achieve the optimum Webthe pH of the sample from station 10 (farthest into the east bay) dropped almost two pH units with a 100 ppm alum dose. However, pH and turbidity measurements taken after 24 hrs showed that pH had gone back up by 0.6 pH units while turbidity dropped slightly. These initial results show that alum is very effective in reducing the turbidity and WebJun 27, 2024 · The chemical formula for the reaction of aluminum in the presence of oxygen is: Advertisement. 4Al + 3O 2 --> 2Al 2 O 3.
