Our previous work (Safarikova et al., 2013) showed that a presence of AOM (or especially Cellular Organic Matter - Proteins, COM) fundamentally influences the coagulation efficiency due to AOM/protein-kaolin interactions and thus, we can assume/believe that characteristics of impurities and their interactions have just as significant effect on aggregate properties as hydrodynamics. Therefore, this work has been focused on the influence of kaolinite particles (that represent turbidity) and COM of cyanobacteria Microcystis aeruginosa on size, structure and shape of aggregates formed by coagulation with two conventional coagulants (ferric and aluminium sulphate). At first, kaolinite and COM were used separately and then simultaneously and they were coagulated under different shear rates. Thus, the effect of single impurities and their mutual interaction on the aggregate properties could be compared.
