Sewage treatment PAC

PAC (poly aluminum chloride) is a kind of new water purification material and inorganic large-molecular coagulant. It is a kind of water-soluble inorganic large-molecular polymer lying between AlCl3 and Al(OH)3, its chemical structural formula is [Al2(OH)nCl6-nLm], in which m stands for the polymerization degree and n stands for the neutralization degree of PAC products. The m value is mediate and n = 1-5, and it is the agglomerate circular chain body with high charge amount and Keggin structure, and it has the electrical neutralizing and bridge connection effects to the gel and particles in water, and it can also eliminate the toxic matter and heavy metal ions; its characters are stable. The examination method can be set according to the national standard of GB 15892-2003. Because of the bridging effect of hydroxyl ion and the agglomeration effect of multivalent anion, the generated PAC is a kind of inorganic large-molecular water processing reagent with relatively larger molecular weight and higher charges.


The ingredient of PAC:

The ingredient of PAC is mainly aluminum oxide, and its molecular formula is [Al2(OH)nCl6-n·xH2O]m(m≤10,n=1~5); it has the circular chain body with larger charges and Keggin structure, and it has the electrical neutralizing and bridge connection effects to the gel and particles in water, and it can also eliminate the toxic matter and heavy metal ions; its characters are stable. The examination method can be set according to the national standard of GB 15892-2003. Because of the bridging effect of hydroxyl ion and the agglomeration effect of multivalent anion, the generated PAC is a kind of inorganic large-molecular water processing reagent with relatively larger molecular weight and higher charges.

It is also called basic aluminum chloride or PAC, or poly aluminum chloride, or complex poly aluminum chloride.
