Modeling a hybrid system for electrical generation and wastewater treatment using photovoltaic and fuel cells

The need to shift to eco-friendly fuel and to recycle wastewater is increasing rapidly with the depletion of non-renewable energy resources and scarcity of water. This study highlights importance and need to promote the efficiency of clean processes for wastewater treatment. It also examines sound environmental methods for water generation with a special focus on solutions for remote areas with limited electricity, sewage networks and irrigation water. Such methods employ modern technology for treatment of wastewater for power generation purposes. The study further proposes a power management strategy for solar and fuel cells system for domestic use in Hebron City. The design was developed to meet total load demand without necessarily being connected to the grid. However, double chambered microbial fuel cell (MFC) prototype was used to treat domestic greywater and to generate some electricity. Chemical oxygen demand removal efficiency achieved was 73.6% and 65.4% for dissolved solids removal. The performance of the MFC decreased, when the wastewater concentration was decreased. Thus, MFC can provide clear water, which can be electrolyzed by excess power from PV panels into Hydrogen and Oxygen. Hydrogen will be used to generate the electricity by fuel cell.
