Effect of mixing intensity onto kinetics of flock growth in an agitated tank

Original language description

The effect of mixing intensity onto kinetics of flock growth and shape characterized by the fractal dimension was investigated. The experiments were carried out in a baffled tank agitated by a Rushton turbine at the mixing intensities 40, 64 and 95 W/m3and kaolin concentration of 0.44 g/dm3. The size and shape of flocks were investigated by image analysis. The flock growth kinetic data was fitted according to generalized correlation proposed by the authors. The dependences A f * = 85.66.eV 1/2, df eq max = 0.623.eV-1/4 and [NtF]max = 1245 were found for model parameters. The fractal dimension Df2 was found to be independent of flocculation time and mixing intensity and its value of 1.469 ? 0.037 was determined as an average for the given conditions.
