“…The wastewater released by the beverage industry typically has low concentrations of heavy metals and pesticides but high levels of organic compounds, as evidenced by high chemical oxygen demand (COD) values (~40,000 mg L −1 ) [3]. Therefore, it is supposed to be high-strength wastewater (COD > 2000 mg L −1 ) [4,5]. Discharging this hazardous and toxic fluid into natural water bodies may result in severe pollution of ground and surface water, presenting a risk to animal and human health [6].…”

The world’s ever-growing population is driving an increased demand for clean water, which makes treating and reusing wastewater an essential practice. In recent years, biological and physicochemical methods have been preferred for wastewater treatment, with combined systems proving particularly effective. In this study, the combination of anaerobic digestion (AD) and electro-oxidation (EO) was investigated as a process for removing chemical oxygen demand (COD) from actual beverage wastewater. The effect of hydraulic retention time (HRT) on AD, electrolysis time, sodium chloride (NaCl) dosage, initial pH, and electro-properties on EO was investigated. At optimum conditions, namely an HRT of 2 days for AD, NaCl concentration of 3 g L−1, 80 min of EO time, natural pH (7.45), and applied voltage of 20 V for EO, the removal efficiency for COD was an impressive 96.47%, with energy consumption and specific energy consumption calculating 177.33 kWh m−3 and 33.79 kWh kgCOD−1, respectively. The amount of by-product gases (CH4 and H2) were also meagerly determined in this study. The results confirm that combining the AD and EO methods is an effective COD removal solution that can benefit the industry, while also offering a sustainable solution to combat water scarcity and meet the growing demand for clean water.

Industries play an important role in the economic growth of any nation, whereas they release pollutants, which impact our environment seriously. Owing to the rapid climate change and global warming, our earth is searching for different sustainable energy technologies. Microbial fuel cell technology is emerging as one of the most versatile sustainable energy technology, with their ability to tap the energy stored in the wastewater and convert it directly into electrical energy. Though MFC research is still in its nascent stage, its theoretical superiority makes it a unique technology, which can be developed into a self‐sufficient system for wastewater treatment in the near future. Brewery industries consume large quantities of water for beer production and hence release large quantities of wastewater. The chemical energy stored in the brewery wastewater could be converted into useful bioelectricity by MFC technology compared to other traditional wastewater treatment technologies, which are all energy intensive. Brewery wastewater, rich in biodegradable organic matter with their non‐toxic nature, makes it a highly suitable substrate for MFC. It is one of the few substrates that have made it to pilot‐scale studies worldwide. This study aims to review the microbial fuel cells with brewery wastewater as their substrate. It will elaborate the different configurations of MFCs employed for brewery wastewater so far, their power producing ability and wastewater treatment efficiency. The critical factors that influence these MFC systems will also be discussed. Finally, this article also identifies and suggests different strategies to improve the performance of such MFC systems.
