25 KG/BAG PAC Yellow Powder Polyaluminium Chloride Used as Water Treatment
Polyaluminum chloride (PAC) is an inorganic substance, an emerging water purification material and an inorganic polymer coagulant, referred to as polyaluminum. It is a water-soluble inorganic polymer between AlCl3 and Al(OH)3. The general chemical formula is [Al2(OH)nCl6-n]m, where m represents the degree of polymerization and n represents the PAC product. Neutral degree. n=1~5 is a highly charged polymeric ring chain with a Keggin structure, which has a high degree of electrical neutralization and bridging effect on colloids and particles in water and can powerfully remove micro-toxic substances and heavy metal ions, with stable properties. The method can be inspected according to the national standard GB 15892--2003. Due to the bridging effect of hydroxide ions and the polymerization of multivalent anions, the produced polyaluminum chloride is an inorganic polymer water treatment agent with a larger relative molecular weight and higher charge.
The color of this product is yellow . It has strong bridging adsorption properties. During the hydrolysis process, physical and chemical processes such as aggregation, adsorption and precipitation occur. The fundamental difference between polyaluminum chloride and traditional inorganic coagulants is that traditional inorganic coagulants are low-molecular crystalline salts, while the structure of polyaluminum chloride is composed of polycarboxylic complexes with various shapes. It has fast flocculation and precipitation speed and is suitable for use. It has a wide pH value range, is non-corrosive to pipeline equipment, and has obvious water purification effect. It can effectively remove SS, COD, BOD and heavy metal ions such as arsenic and mercury in water. This product is widely used in drinking water, industrial water and sewage treatment. field.

Polyaluminum chloride has properties such as adsorption, cohesion, and precipitation. It has poor stability and is corrosive. If it accidentally splashes on the skin, rinse it with water immediately. Production workers must wear work clothes, masks, gloves, and long rubber boots. Polyaluminium chloride has the advantages of good spray drying stability, adaptability to wide water areas, fast hydrolysis speed, strong adsorption capacity, large alum flowers, dense mass and fast precipitation, low effluent turbidity, and good dehydration performance. Spray drying products can ensure safety, reduce water accidents, and is very safe and reliable for residents' drinking water. Therefore, polyaluminium chloride is also referred to as high-efficiency polyaluminum chloride, high-efficiency PAC or high-efficiency spray-drying polyaluminum chloride. Polyaluminium chloride is suitable for raw water of various turbidities and has a wide pH range. However, compared with polyacrylamide, its settling effect is far inferior to polyacrylamide.
