Usuage: 1. For solid PAC, dilution is necessary before being dosed. Dilution proportion for solid product is 5%-10%, and for liquid product, 5%-50%(based on weight percentage). 2.The specific dosage is based on the flocculation test and on the trail. Normally, the dosage of solid is 1-15g/MT, the dosage of liquid product is 3-40g/MT 3. Its acidity is lower than other inorganic coagulants. 4. The PAC solution can not be place more than one week.
