Polyaluminum choloride PAC in abbreviation ( polyaluminum in brief, alkaline chlorination aluminum, flocculant , PAC) [Molecular formula] [AL2(OH)LnCL6-n]m [Technical standard] product quality is up to national standard of GB15892-2003 [Product property] polyaluminum choloride( the alkali type chlorination aluminum) brief name PAC is a new type inorganic polymer coagulant. It lies between the AlCl3 and Al(OH)3 of outcome. [Main characteristics] Compared with other coagulant, it has advantages as follows: 1, Wide application, adapting water extensively. 2, Unnecessary to add alkaline auxiliary, if meeting deliquesce, invariable in effect. 3, Easily and quickly forming big alumina, precipitating. 4, Large scope of suitable PH value (5 - 9), and after treating, processing aqueous PH value and alkalinity of water descend very little. 5, When the water temperature is low, precipitating effect be kept stably. 6, Alkali degree is higher than the other aluminum salts, iron salts, develop little erosion to the equipment. 7, High validity and easy to be stored and transported. [Product usage] Poly-aluminum can remove germ, deodorization, color, fluorine, aluminum, chrome, hydroxybenzene , oil cream, mud, heavy metals salt, radioactive contamination waste, and has extensive usage towards purifying various water. For instance: 1, purifying domestic drinking water and domestic polluted water. 2, purifying industrial water, industrial waste water, the mining and oil field recycling water. 3. purifying water during paper-making, smelting, washing coal, leather and all kinds of chemical industrial waste water treatment. [operation instructions] 1. Solid medicine according to the usage measure, diluting it at the times of5-15 times. 2. Dosage according to the different turbid degree of raw water, measure the best medicine quantity, generally turbid (the muddy degree is in the 100-500 mgs/L) water, each time 10-20 kilograms for per kiloton water, non-drinking and turbid industrial dirty water increase the amount accordingly. 3.Cream-colored and milky poly-chlorination aluminum as exported products, the salinity is comparatively lower. The cream-colored salinity is 40-60±5% and milky salinity is 50-75±5%, while using, adding amount is comparatively smaller.
