ABSTRACT:
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 0.1 MPa - the ceramic membrane and 0.2 MPa – the polymer membrane at a temperature of 20°C. The effectiveness of the process had been assessed by various physical and chemical analyses (pH, turbidity, color, absorbance, TOC and phenol index). There was included the toxicological assessment (by applying as an indicator organism the bioluminescence bacteria Aliivibrio fischeri) and microbiological assessment of tested samples. During filtration there was studied the hydraulic efficiency of membranes. 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 had been noted in the case of polymer membrane than ceramic membrane. However, the polymer membrane, in the comparison to the ceramic membrane, was more susceptible to pore blocking, which caused the reduction of hydraulic efficiency. Regardless of what type of membrane the permeats were not toxic and did not contain microorganisms.
