Bioelectrochemical System in Wastewater Treatment: Resource Recovery from Municipal and Industrial Wastewaters

Due to large quantity and containing rich resources (e.g., chemical energy, metals, fresh water and nutrients), recovery resources from municipal and industrial wastewaters can be considered where resource recovery economies can be applied. Simultaneously, resource recovery during wastewater treatment will make treatment processes more economically viable and compliant to increasingly tight environmental regulations. Bioelectrochemical systems (BESs) have emerged as a platform technology to recover resources from wastewater treatment. In this chapter, a comprehensive and critical review of resource recovery via BES from wastewater is conducted. The basic information of BES as well as the processes of resource recovery through BES at the laboratory and plant scale is introduced. Furthermore, the current challenges related to the BES applications for resource recovery and the possible development directions are discussed.
