Abstract:
Water and energy security continue to be primary threats to our lifestyle. The need of
alternate eco-friendly fuel to generate electricity and recycle wastewater is increasing
rapidly with the depletion of non-renewable electrical energy resources and scarcity
of water. This study represents the importance and the necessity of increasing the
efficiency of clean processes that treat the wastewater. Furthermore, generating
electricity by environmental methods and focusing on solutions for remote areas that
suffer from limited electrical and sewage networks were presented in a modern
technique of treatment and generation the power. This study provides a power
management and generation strategy for solar and fuel cells system for houses in
Hebron City with a simulation of the system. The design was developed to meet total
electrical load demand without need of grid connection. The models of simulation
facilitate more understanding of the system. Thus the electrical components of the
system, like photovoltaic panel, PEM fuel cell, electrolyzer, control management of
hybrid system are modeled as a Simulink blocks by using matlab simulation program.
The simulation show performance of electrical devices and load during the day. Also
show the amount of hydrogen produce and consume during the 24 hours. A prototype
design of MFC is applied. However, double chambered Microbial Fuel Cells (MFC)
prototype in batch and semi-batch conditions was used to treat the house greywater
and to generate some electricity. Chemical oxygen demand removal efficiency
achieved in batch and semi-batch was 45.29%, 55.37% respectively and 61%, 75%
for dissolved solids removal. The performance of the MFC decreased, when the
wastewater concentration was decreased. Thus, MFC can provide cleared water and
the maximum current obtained from grey wastewater was 0.73mA. Then this water
can be electrolyzed by excess power from PV panels into Hydrogen and Oxygen.
Hydrogen will be used to generate the electricity by Fuel cell. Thus the recycling
water cover the demand of water by electrolyzer, also feed water for irrigation around
the home.
