Abstract:This article presents the results of research on the strength of "Monoraphidium contortum" and "Microcystis aeruginosa" cell aggregates, with assumption of spherical and fractal structure of the flocs. The method of computer analysis of the microscopic image was used in the research, which made it possible to determine the size and morphological parameters of phytoplankton cell aggregates formed as a result of coagulation with FeCl3. The equivalent diameter and fractal dimension of aggregates allowed us to assess the resistance of the aggregate to shear forces. ; Based on the obtained values of the strength constant, it was found that "M. aeruginosa" aggregates were characterized by greater strength to the action of shear forces compared to "M. contortum" aggregates. The differences in the strength of the aggregates of the studied species were more noticeable when interpreted based on the assumption of the fractal structure of the aggregates. These differences can be important in water treatment - adjusting coagulation parameters based on phytoplankton characteristics can improve process effectiveness.
