Abstract :
Poly diallyl dimethyl ammonium chloride (PDMDAAC) is a cationic organic polymer flocculant, The aim of this work is to use PFS or PAC for treating surface raw water and PDMDAAC as coagulant aid. Electron microscope was used to observe flocs morphology and study PDMDAAC coagulation aid morphological change, floc image with microscope camera system analysis, calculation of floc fractal dimension. The results show that the, PDMDAAC in dealing with the surface raw water to play a good coagulation aid effect. Microscope and image analysis system of flocs morphology show that fractal dimension of morphology of PFS and PFS/PDMDAAC were 1.521, 1.544, and fractal dimension of morphology of PAC and PAC/PDMDAAC were 1.303, 1.395, respectively. Floc fractal dimension changes to better reflect the flocculation level and treatment effect for the establishment of floc fractal dimension number of changes in the coagulation control is provided for reference.
