Manufacture PAC 28% Yellow Powder Polyaluminium Chloride Chemical PAC Industrial Grade
Polyaluminium chloride, abbreviated as PAC. Commonly referred to as water purifier or coagulant, it is a cationic inorganic polymer flocculant with multiple hydroxyl groups and multi-core complexes between ALCL3 and AL (OH) 3. The solid product has a yellow powder appearance, is soluble in water, has strong bridging adsorption, and is yellow or light yellow in color. This product has strong bridging and adsorption properties. During the hydrolysis process, physical and chemical processes such as coagulation, adsorption, and precipitation occur.

Characteristics of polyaluminum
1. The water quality purified by using polyaluminum chloride is better than that of aluminum sulfate coagulant, and the cost of water purification is 15-30% lower compared to it.
2. The formation of flocs is fast, the settling speed is fast, and the processing capacity is greater than traditional products such as aluminum sulfate.
3. The alkalinity of the water consumed is lower than that of various inorganic coagulants, so it is possible to avoid or reduce the use of alkaline agents.
4. Adapted source water pH 5. 0-9 0 range can be condensed.
5. Low corrosiveness, good operating conditions.
6. The solubility is better than aluminum sulfate.
7. Treating water with less increase in salt content is beneficial for ion exchange treatment and high-purity water production.
8. The adaptability to source water temperature is better than inorganic coagulants such as aluminum sulfate.
Application of polyaluminum
Usage and precautions of polyaluminum chloride
1.It is an inorganic polymer compound that is easily soluble in water and has a certain degree of corrosiveness;
2. According to the different water quality of the raw water, a small trial should be conducted before use to determine the optimal dosage (reference dosage range: 20-800ppm);
3.Pay attention to observation and adjustment during operation. If there are few alum flowers and high residual turbidity in the sedimentation tank, the dosage is too low. If there are large alum flowers and high residual turbidity in the sedimentation tank, the dosage is too large and should be adjusted appropriately
4.Dosing equipment should be corrosion-resistant
5.Polyaluminum chloride agents from different manufacturers or brands cannot be mixed and must not be mixed with other chemicals.
6.The original solution and diluent are slightly corrosive, but lower than other inorganic coagulants.
Packaging and storage shelf life of polyaluminum chloride
1. External plastic woven bags with plastic film sets inside, each bag weighing 25kg net, can also be modified according to user requirements, and liquid polyaluminum chloride is also available for sale.
2. This product is prohibited from being mixed with toxic substances, transported, and stored. The product should be stored indoors in a dry, ventilated, and cool place, and should not be affected by moisture.
3. Be careful when handling during loading and unloading. The shelf life of solid polyaluminum chloride products is one year, but if it exceeds one year, it is not ineffective. However, it is necessary to increase the dosage to achieve significant results.
