Numerical Optimization of Wastewater Treatment Plant Design for a High-Nitrate Industrial Waste
Publisher: ASCE
Abstract: This study develops an optimal design of a municipal water resource recovery facility (WRRF) to treat a high-nitrate industrial waste. The study demonstrated two basic results: first, that a numerical optimization scheme ...
Phosphorus Leaching Behavior from Extensive Green Roof Substrates
Publisher: ASCE
Abstract: The substrate is the key component of a green roof system that directly influences the system’s stormwater mitigation performance; however, it is also identified as a potentially significant source of contaminants. It is ...
Adjusting Error Calculation to Account for Temporal Mismatch in Evaluating Models
Publisher: American Society of Civil Engineers
Abstract: A new method is proposed to compute prediction errors so as to not penalize models for good predictions with a temporal error. Traditional goodness of fit measures are based on model error calculated by pair-wise comparison ...
Multiyear Study on Phosphorus Discharge from Extensive Sedum Green Roofs with Substrate Amendments
Publisher: ASCE
Abstract: Green roofs are implemented for providing urban ecosystem services like stormwater management, but they have also been identified as a potentially significant source of phosphorus in the runoff, which may cause concern for ...
Characterization of Nitrogen Discharge from Extensive Sedum Green Roofs with Multiple Amending Designs and Materials
Publisher: American Society of Civil Engineers
Abstract: Green roofs are effective stormwater control measures for mitigating urban hydrology; however, their potential to manage nutrient discharges has not been consistently documented. Thirty-two pilot scale newly constructed ...
Predictor-Independent Linear Models Relating Lognormally Distributed <i>Escherichia coli</i> and Fecal Coliforms
Publisher: American Society of Civil Engineers
Abstract: Following an EPA recommendation many states switched to
Prediction of Boundary and Stormwater <i>E. Coli</i> Concentrations Using River Flows and Baseflow Index
Publisher: ASCE
Abstract: E. coli (EC) concentrations of the upstream boundary, tributaries, and stormwater in the lower Passaic River at Paterson, New Jersey, were modeled using multivariate polynomial regression (MPR). Baseflow indexes (BFIs) and ...
Remediation of Chromium-Contaminated Soils: Bench-Scale Investigation
Publisher: American Society of Civil Engineers
Abstract: A feasibility study was performed to remediate chromium-contaminated soil by cold top ex situ vitrification. This paper describes the initial conceptualization of the research demonstration and the results from the bench-scale ...
