Poly aluminum chloride-WADE

Poly aluminum chloride (this product Crforide) PAC, also known as basic aluminum chloride or coagulant etc., polymerization aluminum chloride is between AlCl3Al (OH) between a water soluble inorganic polymer, chemical formula [Al2 (OH) nCl6-n]m where M represents the degree of polymerization, n the neutral level of PAC products. Polymerization aluminum chloride color a Midlands color, dark brown, dark gray resin like solid, strong bridging adsorption performance, during the hydrolysis process, accompanied by condensation, adsorption and precipitation and other physical and chemical processes.


The production process of the raw materials to improve the degree of performancepoly aluminum chloride :

1, the polymerization aluminum chloride and traditional inorganic coagulants the fundamental difference is that traditional inorganic coagulant for low molecular crystal salt, and polymerization aluminum chloride structure by changing the form of multi hydroxyl complexes for amorphous inorganic polymer, and exhibit many different from the traditional coagulant specific coagulation function.

2, aluminum acid calcium adjustment method for the production of PAC products, basicity (alkali) can be greatly improved, the production and use of economic benefit is very obvious, basicity from 65% to 92%, the production cost can be reduced by 10%, the use cost can be reduced by 40%. Polymerization aluminum chloride water purification effect is better than other similar products.


Characteristics of poly aluminum chloride:

1, polymerization aluminum chloride at room temperature, chemical stability, long storage without deterioration, solid bare easy absorption of moisture, but does not degenerate, non-toxic harmless.

2, adaptation range of water pH value is 4-14, but optimal pH range for 6-8.

3, water body with strong ability to adapt, fast response, little medicine consumption, low cost of water, alum, settling quickly, consider, improve the utilization rate of equipment


Use of poly aluminum chloride: urban water purification: River water, reservoir water groundwater; industrial water purification, urban sewage treatment, useful materials in the industrial wastewater and waste recycling, promote coal washing waste water coal settlement, starch manufacturing industry in starch recovery; for all kinds of industrial wastewater treatment: printing and dyeing wastewater and leather wastewater containing fluoride wastewater, heavy metal wastewater, oily wastewater, papermaking wastewater, coal washing waste water, mine waste water, brewing wastewater, metallurgical wastewater and meat processing wastewater; sewage treatment: paper sizing, sugar refining, casting of caused by type, wrinkle free fabric, catalyst carrier, medicine refined cement rapid hardening, cosmetics raw materials.


Methods  of poly aluminum chloride

1,, the polymerization aluminum chloride solution, dissolved in a ratio of 1:3, and then diluted to the appropriate proportion.

2, dosage of treated sewage and, generally: liquid products 5-100 grams / ton, solid 20 -- 25 kg / ton, but decided by jar test.

3, polymerization aluminum chloride preparation can be directly into the water, the amount of water by investment quantity and quantity decision, after the water should be stirred evenly.
