Summary: The brewing process generates a significant amount of wastewater and solid waste that needs to be properly and cost-effectively treated to meet discharge standards. Treatment techniques can be combined with energy production strategies to produce biogas, hydrogen, or methane. The article provides an overview of the latest research on brewing wastewater treatment techniques and their potential benefits.

Summary: The present study evaluated the anaerobic co-fermentation of brewery by-products for hydrogen production. The results showed that the removal efficiency of total volatile solids (TVS) reached a maximum of 30.86%. Acetic and butyric acids were the dominant volatile fatty acids produced. The addition of brewer's spent grains (BSG) promoted an increase in nitrogen concentration and decreased the hydrogen yield.

Summary: This study investigated the internal operation efficiency and microbial community diversity of different chambers in an internal circulation (IC) reactor, as well as the energy assessment for hydrogen production through ethanol fermentation. The results showed that the first chamber of the IC reactor had the highest COD removal efficacy and microbial diversity. Additionally, the energy assessment showed that the hydrogen production energy was insufficient to meet the energy consumption of the IC reactor.

Summary: In recent years, anaerobic digestion (AD) has become popular for generating clean energy and managing organic waste. The accumulation of ammonia, acids, and nutrients in the reactor compromises its effectiveness. Biochar (BC) has gained interest in biogas production due to its adaptability. Adding BC to the AD process can mitigate toxic inhibition, reduce methanogenic lag phase, immobilize functional bacteria, and enhance electron transfer. However, more comprehensive knowledge is needed regarding the multifaceted function of BC and its mechanisms in biogas generation in AD.

Summary: This study investigated the effect of protein content on calcium phosphate precipitation and methane production in anaerobic digestion. Results showed that the degradation of amino acids led to pH increase and triggered the precipitation of calcium phosphate. Addition of 25% bovine serum albumin to the wastewater created a favorable microbial community, resulting in a methane production rate of 82.7%. The prevalence of Synergistetes and Methanosaeta indicated that methane was mainly produced through acetate utilization.

Summary: This study developed a three-phase innovative strategy for wastewater sludge treatment, including thermal hydrolysis, fungal fermentation, and anaerobic digestion. Increasing temperature during thermal hydrolysis improved sludge reduction and organic release efficiencies significantly. Fungal fermentation converted waste organics to valuable fiber materials, producing dense and strong paper sheets.

Summary: Anaerobic membrane bioreactors (AnMBR) have limitations in membrane cleaning energy demand and membrane flux. This study presents a novel AnMBR configuration, cloth filter anaerobic membrane bioreactor (CFAnMBR), which uses a commercially available cloth filter technology to improve the membrane flux and reduce the cleaning energy demand. The CFAnMBR demonstrates significant improvement in membrane flux and cleaning energy demand compared to previously reported AnMBR configurations.

Summary: This study evaluated the effectiveness of non-ionic surfactants with different structures in biohydrogen production from palm oil mill effluent. The results showed that adding an appropriate amount of surfactants significantly increased the hydrogen yield in the wastewater. For continuous digestion studies, wastewater supplemented with surfactants outperformed pure wastewater in terms of hydrogen production efficiency.

Summary: The study found that the diatomite-immobilized sludge reactor exhibited more efficient and stable performance in terms of hydrogen production rate compared to the suspended sludge reactor. The highest hydrogen production rate was achieved in the diatomite-immobilized sludge reactor at the optimum organic loading rate. Dual production of hydrogen and ethanol resulted in the maximum energy recovery efficiency.
