Effect of flocculant dosage onto flock size at flocculation in agitated vessel

Original language description

The effect of flocculant dosage onto flock size was investigated in baffled tank agitated by Rushton turbine at mixing intensity 40 W/m3 and kaolin concentration 0.44 g/l. The tests have been carried out at the model wastewater (suspension of tap water and kaolin) at dimensionless flocculation time ntF = 1200. The model wastewater was flocculated with organic flocculant Sokoflok 56A (solution 0.1% wt.) for flocculant dosage 0.4 , 8 ml/l. The flock size and its shape were investigated by image analysis.The simple semiempirical generalized correlation describing effect of flocculant dosage onto flock size was proposed and used for data treatment. The flock shape was characterized by fractal dimension Df2. Using the statistical hypothesis test the fractal dimension was found independent of flocculant dosage and the value Df2 = 1.469 ? 0.086 was determined as average value for given conditions.
