dc.description.abstract | This paper reports on an investigation of the effect of initial solid particle concentrationon flock growth and flock shape characterized by the fractal dimension Df2. The experiments werecarried out in a baffled tank agitated by a Rushton turbine at mixing intensity 64W/m3 and constantdimensionless flocculant dosage DF/ck0 = 4.545 mg/g. The model wastewater (a suspension of tapwater and kaolin) was flocculated with Sokoflok 56A organic flocculant (solution 0.1% wt.). The size and shape of the flocks were investigated by image analysis. The flock growth kinetics was fitted according to a semi-empirical generalized correlation proposed by the authors. The dependences Af = 100.35ck01.532, df,eq,max = 1.0474ck0-0.311 and (NtF)max = 1622ck0-0.393 were found. The fractal dimension Df2 was found to be independent of flocculation time and initial kaolin concentration, and its value Df2 = 1.470 ± 0.023 was determined as an average for the given conditions. | en |
