The aim of this paper was to study meat industry wastewater treatment efficiency during fermentation process in ASBR reactor and post-treatment in UF process. The anaerobic process obtained a considerable degree of the removal of organic pollutants from raw wastewater designated as COD (73.3%), BOD (71.4%) and TOC (83.2%). The concentrations of COD and BOD were 435 and 443 mg/dm3, respectively. The value of TOC reached a level of 136 mg/dm3. Generated biogas in the methane fermentation process of wastewater from meat industry plants was characterized by high methane content (80.9% vol.). In the final part of the experiment, the UF process was used in order to post-treating effluent from ASBR reactor. During the UF process, COD, BOD and TOC parameters were removed at 67.2%, 68% and 70.4%, respectively.
