Evaluation Of A Pilot-Scale Constructed Wetland Treatment System For Renovation Of A Specific Oilfield Produced Water For Beneficial Use, Jennifer Horner
Evaluation Of A Pilot-Scale Constructed Wetland Treatment System For Renovation Of A Specific Oilfield Produced Water For Beneficial Use, Jennifer Horner
All Theses
Oilfield produced waters (OPWs) are brought to the surface when oil reservoirs contained in water-bearing geologic units are extracted. Large volumes of OPW present environmental challenges concerning disposal, as well as potential opportunities for beneficial use if constituents posing risk can be remediated. In this study a pilot-scale constructed wetland treatment system (CWTS) was specifically designed to treat an OPW from sub-Saharan Africa for use in irrigation and livestock watering. Three major objectives were to: characterize and identify constituents of concern in the OPW in terms of beneficial use, evaluate treatment performance of a pilot-scale constructed wetland treatment system for …
Constructed Wetland Treatment Systems For Risk Mitigation Of Energy Derived Waters, Michael Spacil
Constructed Wetland Treatment Systems For Risk Mitigation Of Energy Derived Waters, Michael Spacil
All Theses
Energy derived waters (EDWs) (e.g. petroleum refinery effluents, produced waters) can contain a variety of constituents [e.g. selenium (Se), arsenic (As), low molecular weight organics (LMWOs)]. The overall objective of this research was to provide an approach for remediation of specific constituents of concern in these waters and to measure a relationship between Se removal and abundance of Se reducing microbes. The specific objectives of this research were to: (1) evaluate removal of Se from simulated refinery effluent (SRE) using a pilot-scale constructed wetland treatment system (CWTS); (2) evaluate removal of Se, As, and LMWOs from a generic simulated fresh …
