Abstract

Background and Aims: Identification of microorganisms is an important step in designing and operation of wastewater �treatment systems including MBBR system. This study aimed to identify and separating the bacteria �forming the biofilm used on the bed of MBBR system in hospital wastewater treatment.� Materials and Methods: This experimental study was carried out on a pilot scale of Besat Hospital real wastewater. A �volume of 100 liters of pilot plant was made of Plexiglas and the Kaldnes bed was used in this �study. After the formation of biofilm and microorganisms isolation from the bed firstly, gram and �special stain spores coloring was applied and then routine biochemical tests of microbiology of �dominant bacteria in the biofilm on the Kaldnes bed had been identified.� Results: Bacteria that had been identified in this study included:�E.coli, Enterobacter spp, Bacillus spp, Alcaligenes spp, Proteus spp, Acinetobacter spp, and �Pseudomonas spp.The dominant bacteria found in this study were E.coli, Enterobacter spp, Bacillus �spp.� Conclusion: According to the results of this study, all bacteria identified and isolated from biofilm on the bed �are effective on removing organic materials from hospital wastewater�.�
