Abstract
It is speculated that the most efficient polymer mixing system will expose the greatest amount of polymer charge, thus, maximizing its effectiveness as a coagulant. This study compared the polymer mixing efficiency of the Stranco PolyBlend Unit versus a conventional mixing system. The mixing efficiencies were investigated by measuring the charge density of the polymer solutions obtained from side-by-side comparisons of each system. Cationic polymers used in the testing scheme included those manufactured by Nalco, Stockhausen, and Allied. Viscosity measurements were also performed on some of the active polymer solutions in later runs, to determine the degree of polymer "activation" and the homogeneity of the polymer solution. A comparison of the PolyBlend mixing system with an ideal conventional mixing system on the basis of charge density in the polymer solutions discharged from each system, resulted in a higher charge density in the case of the former for one. cationic polymer studied. The results from the two mixing systems for a second cationic polymer studied were very similar, with a slight edge in favor of the PolyBlend.
