“…For example, materials made from carbon cloth, carbon paper, carbon felt [79], graphite granules, carbon mesh [80], platinum, platinum black and activated carbon with single or tubular or multi-electrode configurations are suitable as electrodes [81]. These electrodes should have properties which render them biocompatible and stable In addition high electrical conductivity, and large surface area is recommended [82,83]. The cathode can be exposed to air or other additional electron acceptors like permanganate, chromium hexacyanoferrate and azo dye, etc.…”

“…The amount of electricity produced in this study, while low (26 mW/m2), was considerably higher than previously obtained with other wastewater types. Research conducted prior to 2004 had shown that organic and inorganic matter in marine sediments could be used in a novel type MFC design [82], making it apparent that a wide variety of substrates, materials and system architectures could be used to generate electricity from organic content with bacterial biomass. Still, power levels in all these applications were relatively low.…”

The quality of freshwater and its supply, particularly for domestic and industrial purposes are waning due to urbanization and inefficient conventional wastewater treatment (WWT) processes. For decades, conventional WWT processes have succeeded to some extent in treating effluents to meet standard discharge requirements. However, improvements in WWT are necessary to render treated wastewater for re-use in the industrial, agricultural, and domestic sectors. Three emerging technologies including membrane technology, microbial fuel cells and microalgae, as well as WWT strategies are discussed in this chapter. These applications are a promising alternative for manifold WWT processes and distribution systems in mitigating contaminants to meet acceptable limitations. The basic principles, types and applications, merits, and demerits of the aforementioned technologies are addressed in relation to their current limitations and future research needs. The development in WWT blueprints will augment the application of these emerging technologies for sustainable management and water conservation, with re-use strategies.

“…Voltage generation from SMFC is very low for powering small devices like wireless sensors and led lighting. SMFC voltage can be increased by the combination of series and parallel connections, but this method requires a large number of SMFC, 14 which requires the large area. When the load (1 kΩ) is added directly to SMFC, the voltage of SMFC starts to fall rapidly as the internal resistance of the SMFC is too large.…”

“…A sensor requires the voltage range of 2.5 to 5.0 V. There is a clear gap between the voltage generated by SMFC and voltage required by the sensor. In order to achieve the power required by a sensor, the parallel and series connection of MFC were made to increase the output voltage (about 3 V) and consequently the power, to supply small sensors and LED lighting . This method of increasing the voltage requires the large area and also voltage fluctuates with time.…”

Summary Sediment microbial fuel cell (SMFC) is a bio‐electrochemical device that generates direct current by microbes present in the soil. The main drawback of SMFC is the low voltage and fluctuations. Therefore, a suitable scheme is required to obtain sufficient voltage with insignificant fluctuation. This paper proposes an energy harvester power management system (PMS) to get rid of low voltage and fluctuation problem of SMFC. The proposed PMS is composed of a dc‐dc boost converter, switches, and super capacitors. The boost converter (using LTC3108 IC) successfully steps up the voltage up to 2.658 V and provides it to the load for 1.5 minutes. Four SMFCs connected with four individual super capacitors and a single boost converter has been used to implement this scheme. In this strategy, the charging and discharging time of the SMFCs are controlled in such a way that the continuous power will be supplied to the load with the optimum number of SMFCs. This scheme is tested on an experimental setup. It is found that the energy harvester PMS supplies a continuous voltage of 2.658 V with the efficiency of 85.46%, which is sufficient to power for small devices such as remote environment sensors, temperature sensors, LED lighting, and submersible ultrasonic receiver.

“…However, PMFC cannot totally substitute the commercial use of fossil energy because the amount of energy produced is relatively low to support human life. This is because the rate of electron transfer from microorganisms to the electrode surface is still slow, where the conductivity and chemical content contained in the soil or mud acts as a planting medium that influences the rate of electron transfer (Aghababaie et al, 2015;Prasad and Tripathi, 2018).…”

The plant microbial fuel cell (PMFC) is a technology built to produce renewable and sustainable electricityin order to meet the increasing global demand. This study demonstrates the potential application of PMFC in swamps dominated by water hyacinth to produce biological energy and plant biomass.In this research, the plant was integrated into a microbial fuel cell that adopts various types of anode materials such as carbon felt, iron and zinc, with a varying distance of 10 and 20 cm between the anode and cathode. Organic compounds emerging from the photosynthesis process were deposited by plant roots, which were then oxidized by bacteria in the mud media. The result showed that the developed PMFC produced a voltage and current density of 244.8 mV and 185.4 mA/m2, respectively, for 30 days, with a maximum power of 100.2 mW/m2 in the cells using zinc as anode material with an electrode spacing of 10 cm. Furthermore, the pH value on PMFC with a longer electrode was higher than the shorter distance due to the protons' inability to move from anode to cathode against the force of gravity. In conclusion, PMFC which utilizes water hyacinth has a good performance in converting chemical energy from the substrate into electrical energy, and has the potential to be developed in underdeveloped areas.
