Coagulation performance and floc characteristics with polyaluminum chloride using sodium alginate as coagulant aid: A preliminary assessment

Section snippets Coagulants PAC with B = 2.0, which is equivalent to the molar ratio of [OH ?]/[Al 3+], was selected for this study.PAC was prepared as follows [17]: predetermined amount of AlCl 3 ¡¤6H 2 O and Na 2 CO 3 powder was fully mixed and then slowly added into deionized water at constant speed for 30 min while stirring at 70¨C80 C to obtain the desired basicity value of PAC.

A Comparative Study of the Performance of Polyaluminum Chloride-Sodium Alginate and Polyaluminum Chloride-Chitosan Composite Coagulants in Dam

Polyaluminum chloride (PAC)/natural polyelectrolyte composite coagulants have received considerable attention recently due to their exceptional properties in drinking water treatment. However, the criteria for selecting polyelectrolytes grafted into the PAC to improve coagulation performance are not yet well defined. For this purpose, we have compared the potential of composite coagulant PAC

application of pac and flocculants for improving settling of solid particles in oilfield wastewater with high salinity and ca2

Application of PAC and flocculants for improving settling of solid particles in oilfield wastewater with high salinity and Ca2

The particle settling was enhanced by adding polyaluminum chloride (PAC) as coagulant and hydrolyzed polyacryamide (HPAM) or cationic polyacrylamide (CPAM) as flocculant. At optimal dose, the particle settling ability with PAC and CPAM was better than that with PAC and HPAM.
