Product Introduction

This product is a new type of highly efficient inorganic coagulant, also known as polyaluminum chloride, abbreviated as polyaluminum, and its English abbreviation is PAC (poly aluminum chloride). It is a water-soluble inorganic polymer between AlCI ₃ and Al(OH) ₃ It is made of synthetic hydrochloric acid, calcium aluminate powder, and bauxite using advanced technology. It has good flocculation effect and low price. Its purification effect is superior to traditional aluminum sulfate and iron salts and other common inorganic salt coagulants. The solid product uses roller drying technology. The product is widely used in industrial wastewater, dyeing wastewater, electroplating wastewater, urban water supply, and industrial water purification.

How to Use

Dissolve the solid product with water at a ratio of 1:3, then dilute it with 10-30 times the amount of water to the required concentration before use. The optimum PH value for addition is 6.5-8.0. Choosing the optimum PH value for addition can maximize the coagulation effect. The dosage can be determined according to the different turbidity of the raw water. Generally, when the raw water turbidity is 100-500mg/L, the dosage per thousand tons is 10-20kg. When the turbidity of the raw water is high, the dosage should be increased accordingly. When the turbidity is low, the dosage can be reduced accordingly. For rural use, the agent can be put into a water tank, stirred evenly, allowed to stand, and the supernatant can be used. Add about 1 gram of this agent per 50 kg. If this agent is used in combination with the polyacrylamide produced by our company, the effect will be even better. For dosing, Guangrui brand anionic polyacrylamide or cationic polyacrylamide can be dissolved together with polyaluminum chloride PAC to form a composite flocculant, or PAC can be added to the water to be treated to form aggregates, and then Guangrui brand anionic polyacrylamide can be added to adsorb and bridge to form large flocculants.

Dosage of Polyaluminum Chloride in Different Water Qualities

1. In low-turbidity water, dilute the solid polyaluminum chloride product with tap water at a ratio of 1:3 (weight ratio) and stir until completely dissolved.
2. In domestic and industrial wastewater, refer to adding about 30g of polyaluminum chloride product per ton of wastewater first. Then add the diluted polyacrylamide product (If the effect is not obvious, please increase or decrease the amount of product added accordingly).
3. In the wastewater treatment of paper mills, use the dosage ratio of low-turbidity water. If the effect is not obvious, it can be added in moderation.
4. When the raw water turbidity is 100-500mg/L, the dosage is 5-10mg, that is, 5-10kg per thousand tons of water. Before use, it is best to conduct a small test according to the water quality characteristics to select the optimal value, and then use it.
