This product is a new type of inorganic coagulant, referred to as polyaluminum chloride, abbreviated as PAC. It is a water-soluble inorganic polymer that lies between AlCl3 and Al(OH)3. This product is made from synthetic hydrochloric acid, calcium aluminate powder, and bauxite using advanced technology. It has good flocculation effects, low cost, and its purification effect is superior to traditional inorganic salts such as aluminum sulfate and iron salts. The solid product uses spray drying technology and drum drying technology. The product is widely used in industrial wastewater, drinking water, urban water supply, and industrial water purification.₃and Al(OH)3₃，之间的一种水溶性无机高分子聚合物，本产品选用合成盐酸、铝酸钙粉、铝矾土以先进工艺制成，具有良好的絮凝效果，价格低，其净化效果优于传统的的硫酸铝和铁盐等普通无机盐类混凝剂，固体产品采用喷雾干燥技术和滚筒干燥技术，产品有工业级黄色粉末和滚筒干燥颗粒状，产品广泛用于工业污水、饮用水、城市给水及工业给水净化等方面。

　　Guangrui brand GB/T22627-2022 industrial grade product physicochemical indicators:

　　Usage Method:

　　Dissolve the solid product in water at a ratio of1:3 to form a liquid solution. Then dilute with clean water by10-30 times to achieve the desired concentration for use. The ideal pH value for dosing is between3.5-5.0; selecting an ideal pH value can maximize the coagulation benefits. The dosage can be determined based on the turbidity level of the raw water; generally when raw water turbidity is100-500mg/L, the dosage per thousand tons should be10-20kg. If raw water turbidity is high, increase the dosage appropriately; if low turbidity occurs, reduce it accordingly.

　　For rural use: Add the agent into a water tank and stir evenly; let it stand until clear liquid can be used. Add about1 gram of this agent for every50 kilograms of water. If this agent is combined with high molecular flocculants produced by this company for use together, better results can be achieved.

　　The dosage of polyaluminum chloride in different water qualities:

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

　　2.In domestic or industrial wastewater: Start with about30g per ton of wastewater for dosing polyaluminum chloride products first; then add diluted polyacrylamide products afterwards.(If results are not obvious please adjust accordingly.)

　　3.In paper mill wastewater treatment: Use dilution ratios suitable for low turbidity waters; if results are not obvious consider adding more cautiously.

　　4.When raw water turbidity ranges from100-500mg/L: Dosage should be5-10mg or5-10kg per thousand tons; conduct small tests based on water quality characteristics beforehand to select ideal values before application.

　　Packaging and storage:

　　(Solid packed in 25Kg bags, inner layer plastic film, outer layer plastic woven bag. Products should be stored in a dry, ventilated, and cool indoor place, avoid moisture, and strictly prohibit storage with flammable, corrosive, or harmful items. (Customer authorized packaging can be processed.)
