This product is a new type of inorganic coagulant, referred to as polyaluminum, with the English abbreviation PAC (poly aluminum chloride). It is made from synthetic hydrochloric acid, calcium aluminate powder, and bauxite through a specific process. It has good flocculation effects, low price, and the solid product uses spray drying technology and drum drying technology. The product is available in industrial-grade yellow powder and drum-dried granular form, widely used in industrial wastewater treatment, drinking water purification, urban water supply, and industrial water purification.

　　Usage Method:

　　Dissolve the solid product in water at a ratio of1:3 to create a liquid solution; then dilute it with clean water by adding10-30 times its volume to achieve the desired concentration for use. The pH value for dosing should be between3.5-5.0 to maximize coagulation benefits. The dosage can be determined based on the turbidity of raw water; generally, when raw water turbidity is100-500mg/L, the dosage is10-20kg per thousand tons of water. If raw water turbidity is high, increase the dosage appropriately; if low turbidity is observed, reduce it accordingly.

　　For rural use: Add the agent into a water tank and stir evenly; let it sit so that clear liquid can be used afterward—approximately1 gram of this agent for every50 kilograms of water. If this agent is combined with high molecular flocculants produced by this company, better results can be achieved. Dosing can involve dissolving anionic polyacrylamide or cationic polyacrylamide produced by this company together with PAC into a composite flocculant or first adding PAC to form aggregates in treated water before adding anionic polyacrylamide produced by this company to bridge and form larger flocs.

　　The dosage of polyaluminum chloride in different water qualities:

　　1. In low-turbidity waters: Dilute solid polyaluminum chloride products at a ratio of1:3 (by weight) with tap water and stir until completely dissolved.

　　2. In domestic or industrial wastewater: Start with approximately30g of polyaluminum chloride per ton of wastewater before adding diluted polyacrylamide products (if results are not significant adjust dosages accordingly).

　　3.In paper mill wastewater treatment: Use dilution ratios suitable for low-turbidity waters; if results are not significant consider adjusting dosages.

　　4.When raw water turbidity ranges from100-500mg/L: Dosage should be between5-10mg per thousand tons of water; conduct small tests based on specific characteristics before full application.
