Our paper presents the results of investigations on the treatment of waters involved in unit process ultrafiltration, hybrid process - coagulation/sedimentation/ultrafiltration and in-line coagulation/ultrafiltration. In membrane filtration that we applied immersed capillary membranes. Simulated water containing humic acids at 30 mg/l was ultrafiltered with a constant volumetric permeate flux amounting to 5.7*10"6 m3/m2-s. Four coagulants were tested, for which the optimal process parameters were determined experimentally. We determined the effectiveness of ultrafiltration and that of the hybrid system coagulation-membrane filtration, basing on measurements of the membranes' yield (permeate flux) and physico-chemical analysis of raw water and permeates. Also residual concentration of metal ions (Al and Fe) in permeates were determined. The application of the hybrid system, combining coagulation and ultrafiltration, offers better effects of the removal of organic pollution.
