Osmotic Bioelectrochemical Systems: A New Approach for Nutrient-Energy-Water (NEW) Recovery from Wastewater
Recovering valuable resources from wastewater will transform wastewater management from a treatment focused to sustainability focused strategy,and creates the need for new technology development.An innovative treatment concept-osmotic bioelectrochemical system (OsBES),which is based on cooperation between bioelectrochemical systems (BES) and forward osmosis (FO),has been introduced and studied in the past few years.An OsBES can accomplish simultaneous treatment of wastewater and recovery of resources such as energy,water,and nutrient (NEW).The cooperation can be accomplished in either an internal (integrated OsBES) or external (coupled OsBES) configuration,through a strong synergy between BES and FO.BES can provide draw solute,perform pre-treatment,or reduce reverse salt flux to help with FO operation;while FO can achieve water recovery,enhance current generation,and supply energy sources to BES operation.Given much progress and interest in the OsBES,this paper has reviewed the past studies,described the current status,presented qualitative and quantitative analyses,and discussed the perspectives of the OsBES technology with a focus on NEW recovery from wastewater.The challenges for further researching and developing OsBES have also been identified.
