Determination of the dosage of conditioner

2021-04-12

There is no fixed standard for the consumption of sludge conditioning agents. The dosage will vary according to the specific nature of the sludge, digestion degree, solid concentration and other specific properties. Therefore, most of them are directly tested in the laboratory or on-site to determine the type and specific dosage of the conditioning agent.

Generally speaking, the dosage of ferric trichloride is 5% to 10%, ferrous sulfate is about 10% to 15%, and the dosage of slaked lime is 20% to 40. %, polyaluminum chloride and polyferric sulfate are about 1% to 3%, and cationic polyacrylamide is 0.1% to 0.3%.
