RISAs(V) and PO4 Removal by an Iron-Impregnated Activated Carbon in a Single and Binary Adsorbate System: Experimental and Surface Complexation Modeling Results
Publisher: American Society of Civil Engineers
Abstract: The objective of this study was to predict As(V) removal by an iron-oxide impregnated carbon (L-Act, 9% Fe(III) amorphous iron-oxide) over a range of environmental conditions using the surface complexation modeling (SCM) ...
Removal of Cs+ and Co2+ from Domestic Wastewater by Adsorbent Addition
Publisher: American Society of Civil Engineers
Abstract: The removal of radiological agents from a wastewater treatment plant that entered via the detonation of a radiological dispersive device (RDD) was investigated. Cobalt and cesium have been the focus of simulated RDD events ...
Modeling Cd Adsorption in Single and Binary Adsorbent (PAC) Systems
Publisher: American Society of Civil Engineers
Abstract: Adsorption of cadmium by two powdered activated carbons (PAC) is investigated in single and binary adsorbent systems. Both PACs are effective in removing cadmium from solution. Cadmium adsorption increased with increased ...
Rotation and Concentration Effects in High-Shear Ultrafiltration
Publisher: American Society of Civil Engineers
Abstract: A parametric waste-specific study was conducted to assess the effects of membrane rotational speed and feed oil concentration on the pressure independent “limiting” flux in a high-shear rotary ultrafiltration (HSRUF) system. ...
As(V) and PO4 Removal by an Iron-Impregnated Activated Carbon in a Single and Binary Adsorbate System: Experimental and Surface Complexation Modeling Results
Publisher: American Society of Civil Engineers
Abstract: The objective of this study was to predict As(V) removal by an iron-oxide impregnated carbon (L-Act, 9% Fe(III) amorphous iron-oxide) over a range of environmental conditions using the surface complexation modeling (SCM) ...
Lead Removal from Soils via Bench-Scale Soil Washing Techniques
Publisher: American Society of Civil Engineers
Abstract: The retention and release of lead from eight different soils collected from the eastern United States were investigated. After characterization using well-established test procedures, the study soils were artificially ...
As(III), As(V), Hg, and Pb Removal by Fe-Oxide Impregnated Activated Carbon
Publisher: American Society of Civil Engineers
Abstract: The removal of As(III), As(V), Hg(II), and Pb(II) by virgin and Fe(III) impregnated activated carbons (FeAC) was investigated. Iron-oxide impregnation increased the pH
Ferrate and Alkaline Chlorination Treatment of Cyanide-Heavy Metal Maritime Wastewater
Publisher: American Society of Civil Engineers
Abstract: Ferrate [Fe(VI)] and alkaline chlorination (AC) were investigated for the treatment of a maritime wastewater (CN, Cd, Cu, Ni, Pb, and Zn) in a seawater matrix. AC reduced CN concentrations but large dosages were required ...
Effects of Operating Parameters in Tubular Ultrafiltration
Publisher: American Society of Civil Engineers
Abstract: A parametric waste-specific study was conducted to develop a more mechanistic understanding of the tubular ultrafiltration system using a surrogate metalworking (MW) fluid as a model waste stream. An average gel layer ...
Modeling As(V) Removal in Iron Oxide Impregnated Activated Carbon Columns
Publisher: American Society of Civil Engineers
Abstract: Iron oxide impregnated onto an activated carbon
