Whilst it may not be a thought that often crosses your mind, sewage plants and the water treatment service as a whole uses a lot of energy whilst performing a vital service. For years scientists have been searching for ways to turn these plants, into a net energy creator, not a net energy user. Two options have always been favoured; using a microbial fuel cell within which bacteria consumes the organic matter to produce an electric current; and, a system of reverse electro-dialysis where positive and negative ions are separated by a series of membranes…
