PAClPoly aluminum Chloride Manufacturing method for a cohesive material of Poly aluminum Chloride

摘要

The present invention is poly aluminum chloride to the sludge (sludge) generated in the water purification plant as a raw material; to produce a (PACl Poly aluminum Chloride) flocculant.; PACl flocculating agent which is widely used in water treatment coagulant for the current bauxite there (Bauxite) have been manufactured by the pressing reaction of aluminum hydroxide (Al (OH) ₃₎ and hydrochloric acid (HCl) one as a starting material the material and aluminum hydroxide amount a situation that relies on imports.; Ln the water treatment plant sludge may contain (20-30%) a large amount of aluminum component due to the injected coagulant from water treatment process.; The present invention is by providing a method for producing a flocculant PACl to extract the aluminum components in the water treatment plant sludge, the significant effect of the recycling and recovery of useful waste material expected.
