Product Overview: Polyaluminum chloride, commonly known as PAC, is an inorganic, water-soluble, high-molecular-weight polymer that falls between ALCL3 and AL(OH)3. Its chemical formula is [AL2(OH)NCL6-NLm], where m represents the degree of polymerization and n represents the neutralization degree of the PAC product. It is a yellow or light yellow, dark brown, or dark gray resinous solid with strong bridging and adsorption properties, and undergoes physical and chemical processes such as hydrolysis, coagulation, adsorption, and precipitation.
The fundamental difference between polyaluminum chloride and traditional inorganic coagulants lies in the fact that traditional inorganic coagulants are low-molecular-weight crystalline salts, while polyaluminum chloride is composed of various poly-carboxylic acid complexes with a variable morphology. It has a fast flocculation and sedimentation rate, a wide pH range, and does not corrode pipeline equipment. It effectively removes color, SS, COD, BOD, as well as heavy metal ions such as arsenic and mercury from water, and is widely used in the fields of drinking water, industrial water, and wastewater treatment.
Product Features:
- High efficiency: Polyaluminum chloride can quickly coagulate and settle various suspended solids, colloids, and organic matter in water, with significant purification effects on water quality.
- Low dosage: Poly aluminum chloride requires a small amount of dosage to achieve a good treatment effect, and it is not prone to secondary pollution.
- Stability: Polyaluminum chloride has good stability and can work stably under a wide range of water conditions.
- Wide applicability: Polyaluminum chloride is applicable to various treatment processes such as precipitation, filtration, and ion exchange.
- Safe and environmentally friendly: Polyaluminum chloride does not contain any toxic or harmful substances and is harmless to the environment and human body.
- Tap water treatment: It can be used for the purification and deep treatment of tap water, removing turbidity, organic matter, and microorganisms.
- Industrial water treatment: It can be used for the solid-liquid separation, precipitation, filtration, and removal of suspended solids, colloids, and heavy metal ions in industrial wastewater.
- Pulp and papermaking: It can be used for deinking, improving whiteness, and separating suspended solids in the pulp and papermaking industry.
- Mining, coal and other industries: It can be used for wastewater treatment and the removal of heavy metal ions in industries such as mining and coal.
