Role of dragon fruit waste (DFW) in microbial fuel cell to treat metal-polluted wastewater with electricity generation
Green technology, known as the microbial fuel cell (MFC), offers wastewater treatment and sustainable power simultaneously. Although there have been substantial advancements, there are still a number of important problems with this technique. Our study presented here has covered the organic substrate challenge of MFC. In prior studies, there was a strong recommendation that fruit waste be used as a source of carbon. In light of this, the waste from dragon fruit was used as a substrate in the present investigation. In 22 days, the study achieved a voltage of 165 mV and a power density of 1.98 mW/m2. Additionally, the removal percentage of Cr3+ and Pb2+ is around 85.39–87.91%, respectively. The operation was carried out with constant 1000 ῼ resistance at all times, whereas the determination of the internal resistance was 694 ῼ. Furthermore, bacterial identification from anodic biofilm indicated that Bacillus-type species such as Bacillus nitratireducens, Pseudoneobacillus rhizosphaerae, and Bacillus paramobilis are the dominant species in the present MFC operation. Furthermore, a thorough description of the investigation’s proposed mechanism—which centers on the metal ion removal process—is given. Finally, mechanism, challenges, and future comments are also included.
期刊介绍:
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
