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

Popis výsledku v původním jazyce

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.
