The Indigenous bio-bed technology with electrical cells were designed to evaluate the Nitrogen removal performance and other pollutants from the river water. The designed Indigenous bio-bed technology were taken an influent levels of CODcr at 250 mg/L, MH4-N and, NO3-N concentrations at 7.5 mg/L for the experiment. The device ran for 48 h for nitrogen remediation of the river water, thus, achieving removal efficiency of 85 %, 97 %, 98 %, 95 % and 92 % for CODcr, NH4-N, NO2-N, NO3-N and TIN, respectively. The highest power and current density generated were 486.86 mWm~(-3) and 4807.02 mA/m~3, respectively. The correlation of both the values of Voltage production and TIN removal performance is shown to be statistically as, R~2 of 0.9861 and 0.9999 of both open and close circuit mode of operation, respectively. The dominant phylum relative abundance deduced the close circuit mode of operation: higher relative abundance than the open circuit.
