Abstract

This work examines the efficacy of artificial wetlands with vertical flow, planted with C. indica and T. latifolia, in treating influent municipal sewage. Water quality measures, such as pH, TSS, TDS, DO, BOD, COD, nitrates and phosphates, were observed for a duration of 28 days. pH was 7.1, TSS removal efficiency was 72%, DO was 5.1 mg/l, TDS reduction was 70%, BOD removal was 75%, COD reduction was 57.24%, nitrate removal was 54%, and phosphate removal was 39% for C. indica. While T.latifolia showed a pH of 7.3, an efficiency of 67% in removing TSS, a DO of 5.4 mg/l, a reduction of 62.24% in TDS, a removal of 71% in BOD, a reduction of 63% in COD, a removal of 46% in nitrate, and a 50% removal of phosphate, the results were comparable. The study finds that in VFCW, both plant types significantly enhance water quality.
