Abstract In this case study the details of its contribution to environmental sustainability as well as in lowering the carbon dioxide emissions produced by traditional wastewater treatment systems. The study was carried out on both untreated and treated wastewater samples and their testing in a lab for more than 18 weeks using standard protocols that covered seven different parameters pH, temperature, BOD, COD, total suspended solids (TSS), ammonium-nitrogen (NH3-N), and phosphate (P). In this study, the designed system was proven to be successful as reduction of COD was found about 77.7% and removal efficiency of BOD of 78.05%. The effluent from designed system had an average TSS content of 44.28 mg/L as opposed to the influent wastewater, which had an average TSS concentration of 152.22 mg/L. The effluent had an average NH3-N content of 1.46 mg/L while the influent's was 27.87 mg/L on average, with a removal effectiveness of phosphorus of almost 79%. The concentration of NH3-N dramatically decreased as a result of the treatment by the adopted plant species in treatment system. The targeted users of designed system can generate revenue as the plant biomass is useful in medicinal and industrial applications.
