Batch investigation of constructed wetland microbial fuel cell with reverse osmosis (RO) concentrate and wastewater mix as substrate

Performance evaluation of microbial fuel cell with sewage wastewater and RO concentrate using composite anode made of Luffa aegyptiaca

“…Experiment‐3 is having highest energy recovery with low organic loading and high RO concentrate, which synergistically influence the flow of ions within the system, reported in our previous work . 3 Experiment‐3 showed more NER s in the first two cycles but maximum NER s were observed as 19.51 Whkg −1 COD −1 in Experiment‐1 during the third cycle. This shows that with low organic loading, more aggregate energy can be recovered if retention time is lower, whereas if retention time in MFCs can be increased, more organic loading in the setup will lead to maximum performance.…”

“…In order to sustain economic development and fulfill the needs of the growing population, feasible and reliable forms of energy are required, 1 which can be incorporated with decentralized wastewater treatment 2 . One of the recently emerging technologies among energy‐efficient systems, Microbial Fuel Cells (MFCs) has invigorated the research interests in recent decades due to their capacity to generate electric power from biomass 3,4 without significant emission of carbon from the source. MFCs have paramount potential because of their ability to treat WW and recover energy out of its biomass simultaneously.…”

Wetlands for environmental protection

“…A study was performed for 69 days to evaluate the potential of two VFCW‐MFCs in the presence and absence of plants ( Canna indica ) operating in batch mode for the removal of COD and TDS and its electricity generation capabilities with a mixture (1:1) of domestic wastewater and reverse osmosis (RO) concentrate. The presence of plant improved the removal of COD (88.1%), TDS (82.05%) and produced maximum cell voltage of 0.86 V when compared with removal of COD (83.1%)and TDS (77.5%) in absence of plant producing 0.75 V cell voltage (Das, Thakur, Chaithanya, & Biswas, 2019). Similarly, Yang, Zhao, Tang, Xu, et al (2019) investigated the performance of CW‐MFCs in the presence and absence of vegetation ( Iris pseudacorus, Hyacinth pink, and Phragmites australis ) and compared with traditional CW in terms of pollutant removal and bioelectricity production.…”

Integrated Constructed Wetland‐Microbial Fuel Cell using Biochar as Wetland Matrix: Influence on Power Generation and Textile Wastewater Treatment

“…Constructed Wetland (CW) frameworks are a blend of physiological and biological mechanisms that efficiently treat wastewater from different sources like domestic, agriculture, industrial and mining with advantages as low operating cost and less maintenance requirements [11–14] . Both Microbial Fuel cells (MFC) and CW comprise of two chambers aerobic and anaerobic where reduction and oxidation occur simultaneously [15] .…”

“…This property of CW‐MFC is an appropriate solution for the treatment of the wastewater by eliminating organic compounds and producing electricity [17] . CW‐MFC systems can be built simply by submerging anode within the soil and placing a cathode near the plant root zone at the top of the soil surface [11–13] . The aquatic plant used in a CW‐MFC system typically develops aerenchyma to adapt to the anoxic state of the water‐logged root.…”
