Implications of Microbial Community to the Overall Performance of Tree-Box Filter Treating Parking Lot Runoff

Most of the studies about stormwater low-impact development technologies (LID) used generalized observations without fully understanding mechanisms affecting whole performance systems from catchment to facility itself. At present, these LID have been treated as black box due fluctuating flow and environmental conditions its operation treatment performance. As such, implications microbial community overall tree-box filter (TBF) were investigated in this study. Based on results, summer season was found be most suitable for microorganism growth greater count TBF during compared other seasons. Least spring which might affected by plant since penology influences seasonal dynamics soil microorganisms. Litterfall fall winter as, season, compositional variety organic matter changes communities. Microbial analyses samples collected revealed that dominant phylum is Proteobacteria all seasons both inlet outlet comprising 37% 47% total count. great importance carbon, sulfur, nitrogen cycling soil. followed Acidobacteria, Actinobacteria, Chloroflexi comprises 6% 20%, 9% 2% 27%, respectively, each season. Each varying correlation different chemical parameters implying effects survival technologies. Depending target biogeochemical cycle, maintaining a good environment specific may decided. These findings useful optimizing design tree filters considering physical, chemical, biological pollutant removal mechanisms.
