Summary: The performance of the upflow anaerobic sludge blanket (UASB) reactor for stable H2 production from starchy wastewater supplemented with groundnut de-oiled cake using mixed consortia was investigated in this study. Limited research on H2 production for UASB reactor has been reported. The operation of the UASB reactor was divided into start-up period and production period, with different hydraulic retention times (HRT) examined for H2 production. The maximum H2 production rate of 12.3 L L-1 d-1 was observed at 3 h HRT. Physicochemical characteristics of the granular sludge were studied, and advanced bio-kinetic models were implemented to analyze the substrate consumption on hydrogen production.

Summary: UASB reactors are a viable option for sewage treatment, but post-treatment is necessary to improve effluent quality. This study established a start-up methodology for a full-scale anaerobic-aerobic system and evaluated removal efficiencies at each step. It was found that anaerobic effluent can deteriorate sludge in the aerobic tank, highlighting the importance of operational aspects.

Summary: Resource reuse has become important in wastewater management, with the use of sludge in agriculture being a major route. Enhanced removal of heavy metals during primary treatment can decrease concentrations in both effluent and sludge for long-term reuse. Specific assessment of technologies for improved heavy metal removal is needed due to variations in total heavy metal concentrations in raw wastewater. Coagulation/flocculation and low-cost sorbents are promising methods for enhancing heavy metal removal during primary settling.

Summary: Enhanced hydrolysis is an effective pretreatment technology for the biological treatment of antibiotic production wastewater. However, the full-scale application of this technology to real oxytetracycline production wastewater requires controlling the organic loading rate to prevent reactor deterioration. The study found that particle formation and blockage were the main causes of reactor deterioration, but this problem could be solved by removing particles from the hydrolyzed wastewater.

Summary: Landfilling is an essential part of solid waste management globally, but it can lead to the release of bioaerosols into the atmosphere, posing health risks to employees and surrounding communities. Studies have shown that landfill air is dominated by microbial dust and pathogenic microbes, with higher bioaerosol concentrations reported in spring and summer due to favorable meteorological conditions. It is recommended that workers in landfill sites use personal protective equipment and practice hygiene to reduce occupational exposure to bioaerosols.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
