Ürün Açıklaması

1. Characteristics and uses of PAC (polyaluminum chloride)

Polyaluminum chloride is an efficient flocculant, water purifier and phosphorus removal agent. Due to its outstanding characteristics and advantages and wide application range, the dosage can be reduced by more than 30% compared with traditional water purifiers, and the cost can be saved by more than 40%. It has become an excellent water purifier recognized at home and abroad. In addition, polyaluminum chloride can also be used to purify special water quality such as drinking water and tap water supply, such as iron removal,  radioactive pollutant removal, and oil slick removal. 

2. PAC Features:

Polyaluminum chloride is between ALCL3 and ALNCL6-NLm] where m represents the degree of polymerization and n represents the degree of neutrality of the PAC product. Polyaluminum chloride abbreviated as PAC is usually also called polyaluminum chloride or coagulant, etc. The color is yellow or light yellow, dark brown, dark gray resinous solid. The product has strong bridging adsorption properties, and during the hydrolysis process, physical and chemical processes such as coagulation, adsorption and precipitation occur.

3. PAC Application:

Polyaluminum chloride is mainly used for urban water supply and drainage purification: river water, reservoir water, groundwater; industrial water supply purification, urban sewage treatment, recovery of useful substances in industrial wastewater and waste residue, promoting the sedimentation of pulverized coal in coal washing wastewater, starch manufacturing Recycling of starch; polyaluminum chloride can purify various industrial wastewater, such as: printing and dyeing wastewater, leather wastewater, heavy metal wastewater, oil-containing wastewater, papermaking wastewater, coal washing wastewater, mining wastewater, brewing wastewater, metallurgical wastewater, meat Processing wastewater, etc.; Polyaluminum chloride for sewage treatment: papermaking sizing, sugar refining, casting molding, cloth wrinkle prevention, catalyst carrier, pharmaceutical refining cement quick-setting, cosmetic raw materials.

 

4. Quality index of PAC (polyaluminum chloride)
What are the three most important quality indicators of PAC (polyaluminum chloride):
 

1,Salinity.

The degree of hydroxylation or alkalization of a certain form in PAC (polyaluminum chloride) is called the degree of basicity or alkalinity. It is generally expressed by the molar ratio of aluminum hydroxide B=[OH]/[Al] percentage. The salinity is one of the most important indicators of polyaluminum chloride, which is closely related to the flocculation effect. The higher the raw water concentration and the higher the salinity, the better the flocculation effect.

2,pH value.

The pH of the PAC (polyaluminum chloride) solution is also an important indicator. It represents the amount of OH- in the free state in solution. The pH value of polyaluminum chloride generally increases with the increase of the basicity, but for liquids with different compositions, there is no corresponding relationship between the pH value and the basicity. Liquids with the same salinity concentration have different pH values when the concentration is different.

3,alumina content.

The alumina content in PAC (polyaluminum chloride) is a measure of the effective components of the product, which has a certain relationship with the relative density of the solution. Generally speaking, the greater the relative density, the higher the alumina content. The viscosity of polyaluminum chloride is related to the alumina content, and the viscosity increases with the increase of alumina content.
