Olla pot coupled microbial fuel cell (OPMFC) is an integration of microbial fuel cell (MFC) into the olla pot irrigation system. The main function of the olla pot is to provide sufficient water to the growing plant but it also acts as anodic chamber and ion exchange membrane simultaneously in the OPMFCs. Metallic azo dye acid blue-193 (AB-193) was removed from wastewater using rice straw biomass (RSP). The biosorption process was described taking Langmuir isotherm and pseudo-second order kinetic models into consideration with the R2 > 0.95. The maximum AB-193 dye uptake on the RSP was 55.87 mg/gm at 25 °C. Furthermore, the treated wastewater (TW) was characterized for the application in OPMFCs as anodic substrate. TW fed OPMFCs reported maximum open circuit voltage (OCV) and power density as 662±46 mV and 1.74 mW/m2 respectively. This strategy of integrating biosorption, subsurface irrigation and microbial fuel cell can potentially address the persisting problem of post-biosorption management of treated wastewater in a sustainable manner.
