Introduces poly aluminum chloride
[ Chinese name ] , commonly known as water purification agent , also known as poly aluminum chloride , referred to as poly aluminum , the English name of PAC. And basic aluminum chloride, aluminum chloride spray drying belong to the same class of water -related agents. Is a multi- cationic hydroxy inorganic polymer flocculant , polynuclear complex body , the solid product appearance is yellow or white powder having a chemical formula [AL2 (OH) nCL6-n] m. ( Wherein , 1 ≤ n ≤ 5, m ≤ 10), and is soluble in water, there is a strong bridge adsorption, accompanied by an electrochemical process in the hydrolysis , condensation, adsorption and precipitation of other physical changes , the resulting [AL2 (OH) 3 (OH) 3], so as to achieve the purpose of purification .
The main features of poly aluminum chloride
The product is compared with other coagulants , has the following advantages : a wide range of applications , a wide range of water-based adaptation . Easy to quickly form large alum precipitation good performance. Suitable for a wide range of PH value (5-9 rooms ) , and post- treated water PH value and alkalinity decrease is small. Water temperature is low , you can still maintain a stable precipitation effect. Basicity than other aluminum, iron high erosion on small devices .
Poly aluminum chloride purposes:
PAC is an inorganic polymer flocculant . Hydroxyl ions through the polyvalent anionic functional groups and functional groups of the polymerization , resulting in a large molecular weight and has a high charge inorganic polymer . Can be adapted to the range of 5.0-9.0 PH value , the best PH value 6.5-7.6 .
1 can be applied to deal with rivers, lakes and groundwater
2 can be used in the treatment of industrial water and industrial water recycling
   3 can be used in wastewater treatment
   4 can be used in coal wash water recycling and porcelain industrial wastewater .
5 can be used in printing , dyeing , tanneries , breweries , meat processing plants, pharmaceutical plants, paper mills , coal , metallurgy, mining , as well as fluorine , oil and heavy metals in waste water treatment.
6 can be used in wrinkle leather and fabric .
7 can be used in cement solidification and mold casting .
8 can be used in pharmaceuticals, glycerine and sugar refining
