“…It increased after one day to the peak (4.32 W/m 3 of anode volume and 4.013 W/m 3 of cathode volume) are shown in (Figure 7). The peak values of power density in this study more than values that were presented by previous studies for PMFC [27] used algae in biocathode to treat actual wastewater which might be attributed to different system configuration.…”

“…Luz T. et al worked to improve a procedure for biological treatment of wastewater from ethanol and citric acid production industry using the microalga Chlorella Vulgaris and the macrophyte Lemna minuscule [26]. Biocathode microbial fuel cell was used by Ronald et al [27] for biotreatment of oils and fats from wastewater of a chocolate factory in Chlorella Vulgaris microalgal cathode chamber and removal of blue dye brl in the anode chamber of the MFC by the bacterial community.…”

Microbial desalination cell (MDC) offers a new and sustainable approach to desalinate saltwater by directly utilizing the electrical power generated by bacteria during organic matter oxidation. In this study, we used microalgae Chlorella Vulgaris in the cathode chamber to produce oxygen as an electron accepter by photosynthesis process for generate bioelectricity power and treat oil refinery wastewater by microorganisms in both anode and cathode.The power density generated by this Photosynthetic Microbial Desalination Cell (PMDC) with 1KΩ external resistance at the first 4th hr. of operation period was 0.678 W/m3 of anode volume and 0.63 W/m3 of cathode volume. It increased after one day to a peak value of (4.32 W/m3 of anode volume and 4.013 W/m3 of cathode volume). The microalgae growth in the biocathode chamber followed in terms of optical density. The optical density increased from 0.546 at the beginning of the system operation to 1.71 after 24 days of operation period. The percentage removal of chemical oxygen demand (COD) of oil refinery wastewater was 97.33% and 79.22% in anode and cathode chamber, respectively. The microalgae in the biocathode were able to remove volatile compounds causing odor from the influent wastewater. TDS removal rate 159.722 ppm/h with initial TDS in desalination chamber of 35000 ppm.

“…All of these parameters can be analyzed in further studies to facilitate the main steps in microalgal production. New technologies are constantly being studied to optimize future processes; for example, bioelectrogenesis with microbial fuel cells (MFCs) consists of treating different types of wastewater and producing electrical energy, and microalgae can potentially be used in bioelectrochemical systems for power generation and removal of unwanted nutrients . These ideas are of great interest for the future development in processes with long‐term sustainability and environmental benefits.…”

CLEAN Soil Air Water

The search for clean technologies needs to be continued to offer alternatives for achieving sustainable energy production and a sustainable economy. This concern is particularly related to the demands of both producing enough renewable energy to meet future needs and reducing greenhouse gas (GHG) emissions. Microalgae are recognized for several benefits they offer, and in recent years, the use of life cycle assessment (LCA) to evaluate the benefits resulting from microalgae cultivation, harvesting/dewatering, biomass drying, extraction, and byproduct development has stimulated research in this area. Considering the importance of microalgae and clean technologies and the increasing number of publications on these subjects, this review aims to perform bibliometric mapping of such studies from 2008 to 2018. Web of Science and Scopus databases are used to identify leading trends. Visualization of similarities viewer (VOSviewer) software is applied to analyze the interactions among keywords. The results of this study indicate an association of microalgae and clean technologies and demonstrate that LCA is one of the most common tools used for such analyses. Bibliometric mapping provides relevant data to reinforce this association and understand the main bottlenecks that must be overcome in this field for future progress to be made.

“…Luo et al [34], by reviewing the metabolomic pathways in two-stage AD, concluded that understanding of the microbial dynamics is intrinsic for the smooth operation of the reactors and depends on the equipment configuration. Biogas produced from lignocellulosic waste in a biogas installation can be used for electricity generation using different techniques [35][36][37]. However, currently heat and energy production using a combined…”

Preliminary Assessment of a Biogas-Based Power Plant from Organic Waste in the North Netherlands

et al. 2019

Biogas is expected to play a crucial role in achieving the energy targets set by the European Union. Biogas, which mainly comprises methane and carbon dioxide, is produced in an anaerobic reactor, which transforms biomass into biogas. A consortium of anaerobic bacteria and archaea produces biogas during the anaerobic digestion (AD) of various types of feedstocks, such as animal slurries, energy crops, and agricultural residues. A biogas-fed gas turbine-generator and steam generator produce heat and power. In this study, a combined heat and power installation is studied. The biogas-based power plant treating cow manure, grass straw, and sugar beet pulp was examined using the software SuperPro Designer, and the obtained economic reports are evaluated. From the results, subsidy for electricity does not change the feasibility of the plants in case that cow manure or sugar beet pulp are used as feedstocks. The net present value (NPV) of biogas plants treating cow manure and sugar beet pulp was negative and the subsidy is not sufficient to make profitable these cases. The biogas power plant treating straw showed a positive net present value even without subsidy, which means that it is more desirable to invest in a plant that produces electricity and digestate from grass straw.
