Although wastewater use in irrigation provides one solution to water scarcity, it also presents a threat to
the environment. Thus, wastewater treatment prior to irrigation is necessary. Microbial Fuel Cell (MFC) is
a sustainable technology that treats wastewater and generates electricity simultaneously while leaving
low concentrations of nutrients in the effluent. In order to explore the economic returns of using MFC as
a pre-irrigation treatment method for wastewater, a case study involving fruit processing wastewater in
a semi-arid region was conducted. The potential profit from treated water and produced electricity was
estimated. The analysis showed that MFC is a promising technology that appears to be economically
feasible and that can reduce water and energy shortages.
