Packaging of polyaluminum chloride:
Packaging of polyaluminum chloride and precautions
⒈External-use plastic woven bag with a plastic film set inside. Each bag has a net weight of 25kg. It can also be modified according to user requirements. Polyaluminum chloride is also available for sale.
⒉It is forbidden to mix, transport and store this product with toxic substances. The product should be stored indoors in a dry, ventilated, cool place, and not exposed to moisture.
⒊Be careful when loading and unloading. The storage period of solid products is one year.


Precautions for use of polyaluminum chloride:
⒈Should carry out a small test according to the water quality when using it, and select a good water purification effect and a small amount of input. The solution should be used with the preparation, and the amount of non-drinking water should be selected according to the actual situation.
⒉When using a solid, first add water to dissolve it to form a 10-25% solution, and then dilute with water to the required concentration. When dissolving, first add water to slowly feed the material, and continue to stir.
⒊Water treatment chemicals of different manufacturers or different brands cannot be mixed, and must not be mixed with other chemicals.
⒋The original liquid and diluent are slightly corrosive, but lower than other inorganic flocculants.
⒌Product effective storage period: half a year, solid two years. The solid product can still be used after damp.
⒍After reasonable dosage of this product, the purified water quality meets the sanitation of drinking water.


Polyaluminum chloride is an inorganic polymer coagulant, also referred to as polyaluminum, or PAC in English. It has a relatively large molecular weight and charge due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions. A higher inorganic polymer water treatment agent. In terms of morphology, it can be divided into solid and two kinds, and solids are divided into brown and white according to different colors. Polyaluminum chloride of different colors also has a big difference in application and production technology.
Advantages of polyaluminum chloride products:
Polyaluminum chloride has the advantages of good spray-drying properties, wide water area, fast hydrolysis speed, strong adsorption capacity, large alum formation, fast dense precipitation, low turbidity, and good dehydration performance. Under the same water quality, spray The dosage of dry polyaluminum chloride, especially in the case of poor water quality, the dosage of spray-dried products can be half compared with drum-dried polyaluminum chloride, which not only reduces the labor intensity of workers, but more importantly, users The cost of water production. In addition, spray-dried products can ensure safety, water accidents, and very safe and reliable drinking water for residents. Polyaluminum chloride, referred to as polyaluminum chloride, or PAC. It is made by reaction and polymerization of high-quality raw materials with high usability using the current advanced production technology. All indicators meet or exceed the requirements of the national standard GB15892-2009. Polyaluminum chloride is processed by spray drying process, so it can also be called grade spray-dried polyaluminum chloride. Polyaluminum chloride product characteristics: it has the characteristics of fine powder, uniform particles, easy to dissolve in water, good flocculation effect, purification, low dosage, and low cost. It is suitable for drinking water purification, urban water supply purification and industrial water supply purification. It is suitable for source water with various turbidity. It has a wide range of PH, and the formation of alum blooms is large and fast, and the sedimentation speed is fast.
