Waste water can be a substantial source of energy.In the United Kingdom,the energy content of waste waters ranges from 2.1 kWh m–3 for domestic to 4.7 kWh m–3 for mixed-use (commercial and domestic) water.Typical wastewater treatment plants use high concentrations of bacteria supplied with oxygen,through aeration of the water,to remove the organic matter.The overall energy consumption in conventional plants with this treatment is roughly 0.6 kWh–3 with about half of that used for aeration.Some treatment plants have become energy neutral,
mostly though the production of methane gas from solids captured or produced during treatment .MFCs offer a unique approach to directly capture the energy in water,effectively turning a wastewater treatment plant into a power plant.Exoelectrogenic bacteria release protons into the waste water and transfer electrons to electrically conductive,inert and high porosity anodes — such as carbon cloth,felt and graphite fibre brushes.

废水可以成为能源的重要来源.在英国,废水中的能量达到2.1千瓦时/立方米（家用）到4.7千瓦时/立方米 （工业用水及家庭用水）
传统的废水处理厂使用高浓度细菌辅以氧气,通过给水增氧来去除有机物质.在传统处理厂使用这种方法消耗的能量大概是0.6千瓦时/立方米,其中一半都用以增氧作业.有一些处理厂在能源上通过从固体中提取或从生产过程收集沼气保持平衡.MFC 提供一种独特的方法来直接从水中提取能量,从而有效的将废水处理厂变为发电厂.生电质子细菌通过向废水中释放质子来将电子转化为导电、惰性以及多孔的阳极,如碳化织物,毛毡,石墨刷等等.
