摘要: Tanneries are an important industrial sector in Ethiopia; consequently, gaps wastewater treatment process performance need to be identified as the country increases its emphasis on compliance. A case study was conducted evaluate physicochemical and microbial water quality at a tannery near Addis Ababa. The designed for following: sulfide oxidation; biological oxygen demand reduction; chromium removal. While some of Ethiopia's standards were met through treatment, effluent COD, sulfide, total nitrogen, guidelines not. 16S rRNA gene analysis used community composition across train. results show that common ruminant phyla dominant throughout, with Firmicutes Bacteroidetes comprising 77% 82% relative abundance. Clostridium increased consistently abundance 39% 61% bacterial effluent. Improved is needed meet environmental public health goals. PRACTITIONER POINTS: Case Study Ethiopia shows ineffective chemical pollutants. Microbiological pollutants from systems can introduce agents importance microbiological influent, mixed liquor contains mostly four lead by Firmicutes. Most pathogenic genera found system became decreasing percentage population. comprises up population deserves further evaluation better understand consequences dominance.
