3. INTRODUCTION
MICROBIAL FUEL CELLS
• Chemical energy to electrical energy
• Catalytic reaction of microorganisms
• Bio-electrochemical system
• Microbial Fuel Cells have the potential to
simultaneously treat wastewater for reuse and to
generate electricity; thereby producing two increasingly
scarce resources

4. STATEMENT OF PROBLEM
• Most of the existing wastewater treatment technologi
es are not sufficient to meet the need for water sanita
tion due to rapid industrialization and population gro
wth.
• Energy is a fundamental ingredient in the life of
humans. The need for a reliable power generation
system has never been greater, over the coming
decades, the power generation industries will face a
challenge in meeting the global energy needs.
• Use of the fossil fuels can trigger global energy crisis
and increased global warming hence there is
considerable interest in research fraternity on green
production

5. JUSTIFICATION OF STUDY
• Waste water if not properly handled causes
environmental issues and pollution, and the cost of
waste water treatment is quite expensive and
consume energy too.
• With the introduction of Microbial fuel cell technology
waste water can be managed properly and at the same
time produce energy which can be considered as a
renewable source.

7. AIM/OBJECTIVES
The aim of this project is to provide an alternative
renewable energy producing method and a better waste
water management technique. The objectives of this
project are as follow:
• A cheaper way of waste water treatment.
• A cheaper source of power production
• A sustainable way of energy generation
• Generation of electricity from waste

8. SCOPE OF STUDY
• The scope of this project is to produce a renewable
and sustainable source of energy that also helps in
waste water treatment at the same time.

9. METHODOLOGY
Design
• This design has two different chambers connected
together by a membrane (or bridge). One of the
chambers will contain the waste water while the
other will contain salt water. The chamber that
contains the waste water is sealed air tight that is no
oxygen supply. The second chamber is maintained
under aerobic conditions that assist to produce
oxygen for the aerated water or salt water. The two
chambers are linked by a salt bridge.
