Treatment and water reuse in decentralized systems is envisioned to play a greater role our future urban infrastructure due growing populations uncertainty quality quantity of traditional resources. In this study, we utilized life-cycle assessment (LCA) analyze the energy consumption greenhouse gas (GHG) emissions an operating Living Machine (LM) wetland treatment system that recycles wastewater office building. The study also assessed performance local utility's centralized plant, which was...
Abstract Pyrolysis has been identified as a possible thermal treatment process for reducing perfluoroalkyl and polyfluoroalkyl substances (PFAS) from wastewater solids, though off‐gas the pyrolysis unit can still be source of PFAS emissions. In this work, fate through laboratory‐scale coupled with oxidizer off‐gasses is documented. Between 91.5% >99.9% reduction was observed entire system specific compounds based on targeted analyses. Overall, removed 99.4% moles introduced. Furthermore,...
This research identified suitable conditions for long‐term inhibition of nitrite‐oxidizer bacteria (NOB) in a sequencing batch reactor the treatment centrate by over‐nitrite pathways. The NOB were inhibited free ammonia concentrations greater than 20 mg NH 3 ‐N/L combined with dissolved oxygen concentration less 0.3 O 2 /L and temperature 30°C. experiments performed laboratory‐scale 2.5‐L fed synthetic actual from full‐scale wastewater plant (800 to 1500 4 + ‐N/L). influence...
Addressing BOD5 Limitations through TOC Correlations - A International InvestigationThis research paper presents site-specific correlations between the 5-day biochemical oxygen demand (BOD5) and total organic carbon (TOC) for wastewater treatment plants (WWTPs) representative of various flows, technologies watershed ecosystems. Full-scale long-term quality data including Town Quispamsis WWTP, and...Author(s)Stephen G. NuttJohn TranChris VriezenGraham FugaAllan ZaleskiAlexandre MiotKrishna...
Generative Adversarial Networks have become a core technique in Machine Learning to generate unknown distributions from data samples. They been used wide range of context without paying much attention the possible theoretical limitations those models. Indeed, because universal approximation properties Neural Networks, it is general assumption that GANs can any probability distribution. Recently, people began question this and article line with thinking. We provide new result based on Extreme...
Robust Evaluation Methodology for the Biogas Utilization Alternatives at San Francisco Oceanside WPCPSan Public Utilities Commission (SFPUC) Wastewater Enterprise executed a study that targets determination of best (and highest use of) biogas utilization option(s) Water Pollution Control Plant (OSP), as existing cogeneration facility is nearing end its useful life. In addition, there are two current projects will result in an increase biogas...Author(s)Drury D. WhitlockHumphrey HoDale...

This work addresses large dimensional covariance matrix estimation with unknown mean. The empirical estimator fails when dimension and number of samples are proportional tend to infinity, settings known as Kolmogorov asymptotics. When the mean is known, Ledoit Wolf (2004) proposed a linear shrinkage proved its convergence under those To best our knowledge, no formal proof has been unknown. address this issue, we propose new prove quadratic assumptions. Finally, show empirically that it...
