Bioelectrochemical systems like microbial fuel cells (MFCs) are quaint systems known to metamorphose the chemical energy of organic matter into electrical energy using catalytic activity of microorganisms. A novel continuous Auto Circulating Bio-Electrochemical Reactor (AutoCirBER) was developed to fulfil the gap of 'simple, inexpensive and compact design' that can continuously treat larger amount of organic wastewater at shorter residence time and without consuming external energy for liquid mixing. AutoCirBER eliminated the need for external agitation for liquid-mixing and therefore, energy requirements. AutoCirBER was operated in continuous-mode and hydraulic retention time was optimized. The reactor underwent performance check-up viz. COD removal, net power output, columbic efficiency, sludge generation and an attributional life cycle assessment (LCA) was also conducted. AutoCirBER was sustainable to run in continuous-mode and showed more than 90.4% of COD removal, and 59.55 W.h net annual energy recovery. Experimental LCA of AutoCirBER also displays its environmental feasibility in longer run.
生物电化学系统，如微生物燃料电池 (MFC)，是一种利用微生物的催化活性将有机物质的化学能转化为电能的奇特系统。为了满足“简单、廉价和紧凑设计”的需求，开发了一种新型连续式自动循环生物电化学反应器 (AutoCirBER)，可以在更短的停留时间内连续处理更多的有机废水，而无需消耗外部能源来进行液体混合。AutoCirBER 无需外部搅拌即可进行液体混合，因此也无需能源。AutoCirBER 以连续模式运行，并优化了水力停留时间。该反应器进行了性能检查，包括 COD 去除率、净功率输出、库仑效率、污泥生成和归因生命周期评估 (LCA)。AutoCirBER 可以持续在连续模式下运行，COD 去除率超过 90.4%，每年净能量回收 59.55 Wh。AutoCirBER 的实验生命周期评估也显示了其在更长时间运行中的环境可行性。
