Description: 
 PAC (Polyaluminium Crforide) referred to as the PAC, is often referred to as alkaline or coagulant such as aluminum chloride, which is between AlCl3Al (OH) 3 between a water-soluble inorganic polymers, chemical communication formula [Al2 (OH) nCl6-n] m where m representative of the extent of polymerization, n said the PAC products neutral level. Color yellow, dark brown, dark gray resin-like solid. The product has a strong bridge adsorption properties, in the hydrolysis process, with the condensate, and other physical and chemical adsorption and precipitation processes. 
 PAC with the traditional inorganic coagulant is the fundamental difference between traditional inorganic coagulant for the low molecular weight crystalline salt of the structure of PAC changing the form of hydroxyl complexes composed of multiple, high inorganic amorphous molecule, which is different from the traditional PAC coagulants demonstrated the specificity of many coagulation function. 
 Adjustment Act of calcium aluminum products produced by PAC, basicity (basicity) can be greatly improved, the economic benefits of production and use is very obvious, basicity from 65% to 92%, raw materials costs can be reduced by 10 %, the use of cost can be reduced by 40%. Water production process better than other similar products. 
 Uses: 
 The products are widely used in daily life, water, sewage, industrial waste water purification, low temperature and low turbidity water purification, paper, leather waste water treatment, waste water recycling power plant ash, printing and dyeing, wool, waste removal of COD, Decolorization of BOD and SS purification. 
 Features: 
 ⑴ at room temperature, chemical stability, long storage is not bad, solid bare easy to absorb moisture, but not bad, non-toxic harmless. 
 PH value of water to adapt the scope of ⑵ 4-14, but the range of PH value is 6-8 the best treatment. 
 ⑶ processing water adaptability, quick reaction, consumption of drugs less, and low cost of water, alum big, quick settlement, taking into account, and can improve equipment utilization. 
 Usage: 
 ⑴ the solid product with water at room temperature 1:2.5-1:3 (weight ratio) mixture stirred for 30 minutes, and other drugs completely dissolved, add 30-40 times diluted with water or diluted into a liquid according to the required concentration before use. 
 ⑵ source water turbidity in the 100-500mg / L, the dosage is 5-10mg. Before the best use of small scale based on water quality characteristics, select the best value, and then put into use. 
 Mechanism: a, colloidal substances in water and the role of strong power. b, hydrolysis products of the fine suspension bridge in the water adsorption. c, on the selective adsorption of dissolved substances. 
 Category: 
 a, the liquid form of PAC is not dry, there is no dilution, loading and unloading easy to use, relatively cheap, advantages, disadvantages is the need for tanker transport, the unit transport costs (equivalent to 2-3 tons per ton of solid liquid) 
 b, the solid aluminum chloride dried form, has the advantages of convenient transportation, no tankers, the disadvantage is the use of dilution will also be required to increase the work intensity.
