EN The main objective of this paper was to measure the purification efficiency of the liquid stream in modified swirl settler with a baffle inside the tank. It was found that separation efficiency depended on the size of contamination particles and hydraulic load also. It decreased when hydraulic load was increasing and raised magnitude with bigger diameter of solid particles. Analysis of liquid damming brought about measurement of the pressure drop in function of water volumetric flow rate. The resistance coefficient was calculated based on previously conducted research. Theoretical introduction was made about sedimentation phenomenon and interactions between liquid and solid particles brought by gravity force. Based on literature research and manufacturer catalogues, different technical solutions and constructions of purifying devices like sedimentation tanks were presented. Emphasis was given to the swirl settling tanks, since they are one of the newest pretreatment solutions and exhibit high potential for modification, which can results with higher purification efficiency.
