Treatment of Micro-Polluted Surface Water by Ballasted Flocculation and its Floc Structural Characteristics

In current paper, compared to the conventional coagulation, micro-sand (MS) and magnetic powder (MP) ballasted flocculation were investigated during the treatment of micro-polluted surface water by simulating ActifloTM and SiroflocTM process. Under an optimized operation condition, the optimal turbi...

description In current paper, compared to the conventional coagulation, micro-sand (MS) and magnetic powder (MP) ballasted flocculation were investigated during the treatment of micro-polluted surface water by simulating ActifloTM and SiroflocTM process. Under an optimized operation condition, the optimal turbidity, CODMn and TP removal, 94.5%, 75.1% and 93.0%, respectively could be achieved by the MP process. In further research, pollutants removal efficiency at various settling time (5, 10, 15, 20 min), flocs two-dimensional fractal dimension and average size were simultaneously studied and the relationship among them was also discussed.
