Usages:
Mainly used in purification of tag water and industrial sewage, as well as treatment of special waters, such as oil-containing sewage, printing and dyeing water, radioactive substance-containing sewage, and sewage containing high toxic metals such as Pb or Cr, or containing fluorine, etc. Additionally, it can also be used in such fields as precision casting, medicine and pharmaceuticals, paper making, metallurgy, tanning, and thermoelectricity, etc.
Main Advantages:
(1)Reduce an operation work without dilution, and besides easing labour,
(2)Strong decolorizing and decontamination capacity; its water purification effects are 4~6 folds of that of Al2(SO4)3, and 3-5 folds of that of AlCl3.
(3)It is suitable for a wide PH range, with PH minimal reduction of original water, thus without any corrosion to piping equipment.
