摘要：

In this study, residual polymer concentration in sludge filtrate was measured by measuring the absorbance of samples at 190 nm. In addition, the method was used to determine the optimum polymer dose required to condition sludge. The optimum dose determined by the UV-vis method was compared to the optimum doses determined by the capillary suction time (CST) and filtration tests. The results showed the UV-vis method was in close agreement with the CST and filtration tests in determining the optimum polymer dose. The advantage of the UV-vis method over other methods is that it can be used in-line at wastewater treatment plants for monitoring and optimizing polymer dose.
