Poly Aluminum Chloride (PAC)

Product Detail:

Polyaluminium chloride (Poly Aluminium chloride abbreviation PAC), CAS: 1327-41-9, is a new type of inorganic polymer water purifier. It is easily soluble in water. The hydrolysis process is accompanied by physical and chemical processes such as electrochemical condensation, adsorption and precipitation. The water purification effect is far superior to the traditional low-molecular water purifiers such as aluminum sulfide, ferric chloride, ferrous sulfate and alum.

product features

1) Polyaluminum chloride has large molecular structure, strong adsorption capacity, low dosage and low processing cost.

2) It has good solubility and high activity. The alum flower formed by agglomeration in the water body is large, the sedimentation is fast, and the purification capacity is 2-3 times greater than other inorganic flocculants.

3) It has strong adaptability and is not affected by the pH value and temperature of the water body. The purified raw water reaches the national drinking water standard. After treatment, the content of cations and anions is low, which is beneficial to ion exchange treatment and the preparation of high-purity water.

4) It is less corrosive and easy to operate, which can improve the labor intensity and working conditions of the dosing process.

5) Good coagulation effect can be achieved for raw water with severe pollution or low turbidity, high turbidity and high chroma.

6) When the water temperature is low, the stable coagulation effect can still be maintained.

7) The formation of alum is fast; the particles are large and heavy, the precipitation performance is good, and the dosage is generally lower than that of aluminum sulfate.

8) The suitable pH value range is wide, between 5-9, when excessive dosing, it will not cause the adverse effect of water turbidity like aluminum sulfate.

9) Its alkalinity is higher than that of other aluminum salts and iron salts, so the corrosive effect of the chemical liquid on the equipment is small, and the pH and alkalinity of the water after treatment drop less.

use method

1) Store in a dry, non-direct sunlight, well-ventilated warehouse, and do not mix with strong alkaline chemicals.

2) Liquid products are transported to the warehouse by tankers or packaging barrels, and can be added directly as needed or diluted by 1-3 times when used; when solid products are used, they can be diluted with water to form an alumina content of 5%-10 according to actual needs. % Solution, through a dosing system (such as a metering pump) or directly added to the water to be treated. The specific dilution method is as follows: pour clean water into the dissolution tank (pool) according to the calculated amount, turn on the stirring, pour the polyaluminum chloride powder into the water according to the calculated amount, and keep stirring until the product is completely dissolved. The solution obtained at this time can be added to the water to be treated or stored for later use.

polyaluminum chloride packaging and precautions

1) Solid plastic woven bags for external use, with a plastic film set inside, each with a net weight of 25kg, and the packaging is not priced or reused; liquid tankers are transported or stored in tons of packaging barrels.

2) The product should be stored indoors in a dry, ventilated, and cool place. Be careful when loading and unloading. Keep the packaging bag clean and tidy without damage. After damage, the product is easy to absorb moisture.

3) The shelf life of solid products is two years, and the shelf life of liquids is half a year. After the solid absorbs moisture, it will not affect the use.
