ABSTRACT
Heavy metals in wastewater come from processes related to heavy metals as raw materials and contaminants. Heavy metals pose a significant threat. Bioaugmentation technique that utilizes communities of microorganisms to bioaccumulation heavy metals from wastewater. However, the application of SRB in anaerobic system installations for wastewater treatment needs to continue to be developed with more practical applications. In this study, the enriched SRB colony source was applied to an anaerobic tank. The grown SRB is used to extract heavy metals from wastewater with the addition of sulfate and supporting nutrients. Throughout the treatment process, the anaerobic system with SRB consistently maintained a sulfate removal efficiency of 87-88%, indicating continued sulfate consumption activity by the SRB colony. Despite the high initial concentration of heavy metals, the system effectively removed >91% of Pb, Cd, Zn, and Cr on days 15, 30, and 45. Additionally, the system reduced the Cu content by 43.6%, thereby reaching peak metal removal heavy. the level was 85% on day 30 and decreased slightly to 83% on day 45. This study bridges the gap in understanding the application of SRB in wastewater treatment systems with effective performance.
