MICROBIAL REVERSE ELECTRODIALYSIS

CELL

PRESENTED BY:

WHAT IS IT…???

Produces electricity from waste water.

CONCEPT PROPOSED BY: BRUSE LOGAN (an environmental engineer)

HOW IT WORKS ????

Microbial fuel cells. Uses bacteria. Converts plants and human waste

into electrons.

MICROBIAL ELECTROLYSIS CELL:

It is a bio-electrochemical system that drives a current by mimicking bacterial interactions found in nature.

CONCEPT:

Utilization of potential difference between waste water and fresh water.

PRINCIPLE:

Added ammonium bicarbonate and carbon di-oxide to waste water.

Passed through membranes of MFC.

Separated anions and cations.

REMOVAL OF CHEMICALS FROM WASTE WATER:

By boiling.

Filtration.

ADVANTAGES:

Water purification needs energy.

This method produces electricity on purification of water.

At the rate of 0.98 kwh from 1 kg wastage.

DISADVANTAGES:

Costlier membranes.
