Properties:
The water quality after purification using PAC is better than that of aluminum sulfate flocculant , and the cost of water purification is lower; the floc formation is fast, the settling speed is fast, and the alkalinity of the consumed water is lower than that of various inorganic flocculants, so no or less investment is required Alkali agent and PAC can flocculate in the range of raw water pH of 5.0-90. It is an ideal drug for industrial sewage and wastewater treatment, and is widely used in metallurgy, electric power, tanning, medicine, printing and dyeing, chemical industry and other industries.

Usage:
- 1.Dissolve the solid product into liquid by adding water at a ratio of 1:3, then add 10-30 times of water to dilute it to the required concentration before use.
2. The dosage can be determined based on the different turbidities of the raw water. Generally, when the turbidity of the raw water is 100-500 mg/L, the dosage is 5-10 mg.
Packaging and storage:
PAC is packed in polyethylene plastic bags and woven bags. The net weight of each bag is 25kg. It is stored in a cool and dry warehouse with a shelf life of one year.
Safety and protection:
Weakly acidic, pay attention to labor protection during operation, avoid contact with skin, eyes, etc., rinse with plenty of water after contact.
