2. INTRODUCTION
Current sewage treatment process require large amount of power for
various treatment units.
Most of the useful energy available in sewage itself remains
unrecovered.
We aim to develop a renewable, efficient, eco-friendly and
sustainable method for recycling influent sewage by harvesting
electricity from it and then filtering it to produce a better quality
effluent from this given influent sewage.

3. OBJECTIVES
We will aim at achieving the following objectives:
Producing electricity directly from sewage.
Simple, efficient and cheap treatment of sewage.
Effectively control the following parameters of sewage:
a) pH b) TSS c) Odour d) Chloride e) Colour f) Heavy metals
g)TDS h) BOD

4. METHODOLOGY
We have incorporated two techniques in our project.
TECHNIQUE 1: MICROBIAL FUEL CELL (MFC)
TECHNIQUE 2: HYBRID CARTRIDGE FILTER
The possible work area for the carrying out of the project would
be the Sewage treatment plant of NIT, outside the campus.

5. MICROBIAL FUEL CELL
(MFC)
MFCs produce electricity from sewage and improve its quality
by reducing organic matter.
Proton Exchange Membrane (PEM) separates anode chamber
(containing sewage) and cathode chamber (containing water).
Bacteria anaerobically oxidise the substrate at anode chamber.
Protons generated cross the PEM and enter cathode chamber.
Electrons generated during oxidation pass from bacteria to anode and
then to cathode where they reduce oxygen to combine with protons
and form water.

6. HYBRID CARTRIDGE FILTER
This system will work to further improve the quality of
sewage water efflux out of the MFC. It will consist of sponge
filters between the layers of filtration material.
Sponge filters to remove TSS up to 1µ size.
Granulated zinc carbon alloy to remove Cl2, heavy metals
and bacteria.
Fine mesh carbon block to remove odour, colour,
protozoa and organic contaminants.
Calcite will be used to control pH.

• Miscellaneous: Rs.5000/-
Rs. 19000/-
Total Cost of Raw Materials as indicated above:
Rs. 41000/- + Rs. 19000/- = Rs.60,000/-
Grand Total of Project: Rs.60,000/- (raw materials) +
Rs.10,000/- (mentor) + Rs.30,000/- (students @
Rs.5000/- per student (a total of 6 students involved in
the project)) = Rs.1,00,000/-

9. POSSIBLE OUTCOMES
• This project has been designed to work in small scale because of funds constraints.
• If more funds are available then this project can be made to use in large scale and
produce more improved filter quality.
• The electricity produced can be used in the further treatment processes.
• The improved effluent will put less load on the expense on treatment processes.
