Influence of co-substrate existence, temperature, pH, and salt concentration on phenol removal, desalination, and power generation using microbial desalination cells

Abstract Microbial desalination cells (MDCs) exhibited an economical value with large promises as a useful treatment solution. MDCs threefold applications to efficiently treat wastewater and produce electricity simultaneously accomplish were investigated in this work. The study examined the influence of various performance parameters including co-substrate, temperature, pH, salt concentrations on response three-chamber respect energy recovery contaminant removal (Phenol). system evaluation criteria encompassed chemical oxygen demand (COD), phenol efficiency, Coulombic other such voltage generation power density. maximum COD efficiencies obtained at temperature = 37 °C, pH 7, concentration 10,000 ppm, 80% 74%, respectively. efficiency was 5.3% observed 18 ppm. results show that presence co-substrate improved density; density 52.9 mW/m 2 . principal component analysis elucidated impact rates. With our findings confirmed trends improvement generation, addition increase.
