Polyaluminium chloride use method:

After the solid product is dissolved in water at 1:3, it is used as a liquid, diluted with 10-30 times of fresh water to a desired concentration. The optimal PH value for the dosing is 3.5-5.0, and the best PH value is added to maximize the benefits of coagulation. The dosage can be determined according to the different turbidity of the raw water, and the best dosage is determined. When the raw water turbidity is 100-500mg/L, the dosage per kiloton is 10-20kg. When the turbidity of the raw water is high, the dosage is appropriately increased, and when the turbidity is low, the dosage can be appropriately reduced.

The dosage of polyaluminum chloride in different water quality:

1. in low turbidity water, the solid polyaluminum chloride product is diluted 1:3 (weight ratio) plus tap water and stirred until completely dissolved.
2. in the life and production use of sewage, with reference to each ton of sewage before adding about 30g of polyaluminum chloride products. Then add the diluted polyacrylamide product (if the effect is not obvious, please reduce or increase the product dosage as appropriate).
