Usage of Oleic and Stearic Acids in Mixed Anaerobic Culture for Sulfate Reduction While Inhibiting Methanogenesis
(ASCE, 2022-03-22)In a mixed anaerobic biotreatment process, sulfate is converted into sulfide by sulfate-reducing bacteria (SRB). Sulfidogens and methanogens in a mixed anaerobic culture can compete for electrons. Diverting a larger fraction ... -
Evaluation of the Immobilization of Coexisting Heavy Metal Ions of Pb2+, Cd2+, and Zn2+ from Water by Dairy Manure-Derived Biochar: Performance and Reusability
(ASCE, 2022-03-22)Heavy metals including Cd, Pb, and Zn are prevalent stormwater and groundwater contaminants derived from natural and human activities, and there is a lack of cost-effective treatment for their removal. Recently, biochar ... -
Supervised Stacking Ensemble Machine Learning Approach for Enhancing Prediction of Total Suspended Solids Concentration in Urban Watersheds
(ASCE, 2022-03-31)The potential for stacking ensemble modeling to enhance the performance and generalizability of machine learning (ML) models for the estimation of total suspended solids (TSS) concentration was assessed by comparing the ... -
Improved Models for Chromate Removal Using Ion Exchangers in Drinking Water Applications
(ASCE, 2022-03-12)Chromates are widely used for their anticorrosive properties. Unfortunately, they are hazardous, with environmental agencies regulating their levels to below 10 parts per billion (ppb) in drinking water. Because single-use ... -
Resuspension and Attachment of PhiX174 in Sediment Laden Flow
(ASCE, 2022-03-18)To improve the understating of viral pathogens’ resuspension from bed sediment and their attachment to suspended sediment, a series of flume experiments using a coliphage surrogate, PhiX174, were conducted with two sediments: ... -
