Abstract: Biological methods are used for treatment of municipal wastewater. These processes can be conducted in various kinds of technological systems. In the paper the comparison of characteristic of activated sludge from two types of technological systems is shown. A flow bioreactor with secondary settling tank (system I) and sequential bioreactor (system II) were used. The study showed, that more favorable operating conditions of activated sludge were in the SBR reactor. The activated sludge in SBR reactor had better sedimentary properties, as indicated by values of sludge volume index and flocs’ sizes. This can be connected with the fact that sludge in SRB reactor is not pumped (what occurs in flow systems). Therefore the sludge is not subjected to unfavorable conditions during hydraulic transport (flocs do not undergo the dispersion). Moreover the values of flocs’ sizes, respiratory activity and specific surface area of sludge from II system were higher in comparison with system I.
