| Abstract | The research was intended to study the capability of the Fixed Bed Reactor (FBR) combined with volcanic rocks and local microbial isolates on treating fabric dye wastewater. The microbial isolates were cultivated from the sediment of water channel in Imam Bonjol area, Denpasar City and then attached onto the surface of volcanic rock which was taken from the slopes of Mount Batur. In addition to examine the treatment performance, this research also determined the profile of biomass growth related to the origin of sediment samples as the source of microorganisms, and explain the effect of various nutrient compositions on biofilm formation. Furthermore, this research determines the effectiveness of FBR in reducing color content, COD, and BOD5 of fabric dye wastewater. The research workflow was divided into three stages. The first stage was cultivating microbial isolates with several various nutrients. Second stage was growing biofilm on rock with various media composition, and third was determining the ability of biofilm to reduce color, COD and BOD of dye industries wastewater. The results showed that the nutrient composition presented a significant effect on the growth of local cultures in the active suspension. Furthermore, the composition of media also showed notable effect on the formation of biofilm in FBR. FBR was able to reduce levels of color, COD, BOD5 with successive effectiveness of 87.35% 87.25% and 93.11% in 8 hours of FBR treatment. |
