Performance of a Full-Scale Vermifilter for Sewage Treatment in Removing Organic Matter, Nutrients, and Antibiotic-Resistant Bacteria

The vermifilter (VF) is regarded as a sustainable solution for treating rural sewage. However, few studies have investigated the performance of full-scale vermifilter. objective this study to evaluate in reducing organic matter, nutrients, and antibiotic-resistant bacteria contained Influent effluents were obtained from sewage treatment plant using VF UV disinfection system. results show significant removal (p < 0.05) chemical demand (COD) (77%), biochemical oxygen (BOD5) (84%), total nitrogen (TN) (53%), phosphorus (36%). Seasonality an influential variable COD, BOD5, TN removal. In addition, molecular weight distribution shows that does not generate considerable change matter (COD carbon (TOC)) NH4+-N. system eliminated 99% coliform bacteria; however, they are safe concentrations. Therefore, it possible detect resistant antibiotics ciprofloxacin, amoxicillin, ceftriaxone at 63.5%, 87.3%, respectively, which detected effluents. This potential pollution need optimize be treatment.
