The effluent from the municipal sewage treatment plant was comparatively treated in the ultrafiltration process using ceramic and polymer membranes. Filtration was carried out in the cross-flow system under the conditions of the transmembrane process pressure of 0.1 MPa in the case of the ceramic membrane and 0.2 MPa with the polymer membrane, at a temperature of 20°C. The effectiveness of the process has been assessed by means of various physical and chemical analyses (pH, turbidity, color, absorbance, TOC and phenol index). The toxicological assessment (by applying the bioluminescent bacteria Aliivibrio fischeri as an indicator organism) and microbiological assessment of tested samples were included. The hydraulic efficiency of membranes was studied during filtration. Is was specified that the efficiency of the process depends on the conditions of membrane filtration, wherein the better effects of the removal of organic pollutants have been noted in the case of polymer membrane than with the ceramic membrane. However, the polymer membrane, in comparison to the ceramic membrane, was more susceptible to pore blocking, which caused the reduction of hydraulic efficiency. Regardless of the type of membrane, the permeates were not toxic and did not contain microorganisms.
