Giving waste water the power to clean itself

RATE THIS! +1
Posted in Science on 2nd Mar, 2012 07:21 PM by APM

A technique that combines two novel forms of renewable energy — one relying on bacteria and the other on salt water — generates more electricity than either one alone and cleans waste water at the same time.

 

The Pennsylvania State University researchers show that this configuration can achieve maximum power densities of 3 watts per meter squared, much higher than either technology can achieve on its own.

 

One method for converting this energy to a useable form is to use microbial fuel cells (MFC). These generate electricity by using cultures of microorganisms to break down and oxidize organic matter, a process that releases electrons that migrate towards a positive electrode.

 

To boost the power density of the MFC system, the researchers added a second process, called reverse electrodialysis (RED), in which the salinity gradient between fresh water and sea water is harnessed to generate electricity.

 

The researchers’ system, called a microbial reverse-electrodialysis cell (MRC), sandwiches a reverse electrodialysis (RED) stack made up of only a few pairs of membranes between the two chambers of an MFC, where the proton-exchange membrane would normally be.
