Abstract

Background: Changes in indicator and pathogenic microorganisms in COMPOSTING process can reflect the progression of the COMPOSTING process and the quality of the final product. The purpose of this study was to determine the population changes in indicator and pathogenic microorganisms in anaerobically digested SEWAGE SLUDGE (SS) COMPOSTING process.Methods: In the present study, 3 windrow piles were prepared by mixing green waste as bulking agent with anaerobically digested SS with volumetric ratios of 1: 1, 2: 1, and 3: 1. A pile of SS was also formed without any bulking agent as control. The sampling of compost piles was performed during 3 months of the COMPOSTING process. Compost samples were analyzed for physicochemical and microbial parameters. Findings: The results showed that temperature in the sludge pile did not achieve thermophilic phase. In addition, the 1: 1 pile had shorter thermophilic phase than 2: 1 and 3: 1 piles. At the beginning of COMPOSTING, the total number of coliforms, fecal coliforms, and fecal streptococci were about 109, 108, and 105 MPN/gDW, respectively, in 2: 1 and 3: 1 piles. The number of microorganisms decreased during termophilic phase and reached very low or undetectable concentrations for fecal coliforms and about 100 MPN/gDW for fecal streptococci in these piles. Salmonella decreased with the rising of temperature and reached undetectable concentrations after 19 and 47 days in 3: 1 and 2: 1 piles, respectively.Conclusion: The microbial assay of the COMPOSTING process and final products showed that the 2: 1 and 3: 1 pile achieved thermophilic phase and were successful in the removal of pathogens. Therefore, the agricultural application of the SS composted can be authorized from a microbial point of view.
