Water Research X, Journal Year: 2024, Volume and Issue: 26, P. 100291 - 100291

Published: Dec. 3, 2024

Sudden shocking load events featuring significant increases in inflow quantities or concentrations of wastewater treatment plants (WWTPs), are a major threat to the attainment treated effluents discharge quality standards. To aid real-time decision-making for stable WWTP operations, this study developed probabilistic deep learning model that comprises encoder-decoder long short-term memory (LSTM) networks with added capacity producing probability predictions, enhance robustness effluent prediction under such events. The LSTM (P-ED-LSTM) was tested an actual WWTP, where bihourly total nitrogen performed and compared classical models, including LSTM, gated recurrent unit (GRU) Transformer. It found events, P-ED-LSTM could achieve 49.7% improvement accuracy predictions concentration GRU, A higher quantile data from output, indicated value more approximate real quality. also exhibited predictive power next multiple time steps scenarios. captured approximately 90% over-limit discharges up 6 hours ahead, significantly outperforming other models. Therefore, model, its robust adaptability fluctuations, has potential broader applications across WWTPs different processes, as well providing strategies system regulation emergency conditions.

Evaluating the Mechanisms and Efficiency of Johkasou Systems for Decentralized Domestic Effluent Treatment: A Review

Water, Journal Year: 2024, Volume and Issue: 16(16), P. 2266 - 2266

Published: Aug. 12, 2024

Johkasou systems have emerged as quintessential examples of decentralized wastewater treatment technologies due to their compact design, easy operation, and robust resistance mechanical impact attributes that are particularly effective in mitigating treating rural domestic wastewater. Although the efficiency process removing nitrogen phosphorus has been well-documented, a comprehensive synthesis underlying mechanisms influencing factors is still elusive. This review seeks elucidate these aspects by detailing biogeochemical pathways involved removal, characterizing key microbial consortia, addressing potential accumulation nitrous oxide (N2O). Furthermore, critically examines various media used on nutrient removal efficacy, with particular emphasis nitrogen. It also proposes range practical adjustments design parameters, including dissolved oxygen (DO), pH, temperature, hydraulic retention time (HRT), enhance performance. Finally, implementation integration ancillary processes actual sewage scenarios synthesized, providing theoretical foundation for advancing methodologies areas.
