Integrating the Anaerobic Process with Ultrafiltration in Meat Industry Wastewater Treatment

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.
