Characteristics of Polyaluminum Chloride (PAC) Coagulant Prepared by Baking Process
One new technique was introduced preparing high-efficiency flocculant: polyaluminium chloride (PAC) with the materials of AlCl3·6H2O. Effect of preparing conditions on quality and separation of PAC was tested. The optimal preparing method was: baking temperature 290℃; baking time 30min; maturation time 18h; liquids laying aside time 12h. The structure and form of PAC was studied by scanning electron microscope (SEM), and Al13 was detected by 27Al-NMR. And the flocculating efficiency of PAC was also preliminarily examined by jar test.
