Fractal Dimension of Floc Growth in Micro-Coagulation Stage I: Using to Forecast Water Quality of Settled Water
The coagulation experiments, with Kaolin as objects, aluminum chloride (PAC) as coagulant, were accomplished under different conditions. In the experiment, the particle size distribution and turbidity in water were detected by on-line detector. Result showed that all floc changed in speed in the first 5 min of the coagulation process and the fractal dimension of floc growth in the first 4 min of coagulation process had best linear relation (R2 was biggest and more than 0.92 )with turbidity, total particle number and the number of particle size <5µm of settled water. The fractal dimension had a direct ratio relation with water quality of settled water and could be used as a factor to forecast water quality of settled water.
