The purpose of the paper was to study the dilution-induced effect caused by high hydraulic load on the activated sludge structure and properties. A high hydraulic load rate was simulated in the laboratory. The analysis included area and perimeter automated measurements of activated sludge flocs under different dilution rates. The area of activated sludge flocs has decreased as a result of the initial dilution due to the mechanical disaggregation of large flocs. At the end of the experiment, the
