Abstract

In developing countries such as India, hybrid constructed wetlands have proven to be an efficient technology due to their cost-effectiveness in installation, practicality, operation, and maintenance over the past decades. This study explores the integration of fuzzy modeling with hybrid constructed wetlands and Microbial Fuel Cells (MFC) for efficient power generation during sewage water treatment. There exists a significant gap between treated and untreated wastewater in India. MFCs, a cutting-edge technology, are gaining considerable attention worldwide due to their potential benefits in producing bioelectricity from wastewater treatment. Referred to as ‘Green technology’, microbial fuel cells offer an environmentally beneficial method of generating electricity while simultaneously purifying wastewater. MFCs directly convert the inorganic and organic substances present in wastewater into electricity using microorganisms as catalysts. In a standard MFC, a proton exchange membrane separates the anaerobic anode chamber from the aerobic cathode chamber. Electrons, traveling through an external circuit to the cathode chamber, produce electric current and power. Bioelectricity generation depends on the type of MFC, electrode materials, performance, substrates, design, and technological configuration. The choice of electrode material influences current production and power density; materials with high electrical conductivity, such as copper used for the anode and zinc for the cathode, lead to significant current production. In the study, this configuration achieved a power density of 352.125 mW/m^2 corresponding to a current of 2 mA, with removal efficiencies for COD, BOD, phosphates, and TSS at 64.64%, 77.87%, 70%, and 76.82% respectively.
