Field Trials Of Ex Situ Smouldering Treatment (Starx) Of Oil Sludge, Cody Murray
Field Trials Of Ex Situ Smouldering Treatment (Starx) Of Oil Sludge, Cody Murray
Electronic Thesis and Dissertation Repository
Growing environmental concern and regulations around petroleum producing and refining facilities, along with the divesting of legacy properties, have necessitated the need for rapid, high capacity, and cost-effective treatment technologies for remediating these sites and their produced wastes. Self-sustained liquid smouldering – known as STAR technology - has been studied extensively at small scales and has been proven as an effective in situ remediation technique for heavy hydrocarbons. However, STAR as a large-scale ex situ waste disposal method (STARx) has yet to be demonstrated. Here STARx is evaluated for the first time in soil pile configurations, using an engineered base …
Field-Scale Implementation Of Sulfidated Nano Zerovalent Iron For In-Situ Remediation, Ariel Nunez Garcia
Field-Scale Implementation Of Sulfidated Nano Zerovalent Iron For In-Situ Remediation, Ariel Nunez Garcia
Electronic Thesis and Dissertation Repository
As far back as the mid-1990s, biogenic sulfidation has been observed during the implementation of iron-based materials for groundwater remediation. This phenomenon has largely been a consequence of natural biogeochemical processes and the prospects of utilizing engineered sulfidated zerovalent iron (ZVI) particles – nano- and/or micro- sized – were not extensively explored. More recently sulfidation of zerovalent iron (ZVI) particles has received considerable attention, highlighting the benefits that engineered/abiotic sulfidation can offer to nZVI, but to date, no field demonstration of the technology has been conducted. The first part of this thesis aims to report the unique challenges and unanswered …
Analysis And Control Of Aluminum Concentration In Groundwater: Mathematical Modelling And Laboratory Study, Daria Popugaeva
Analysis And Control Of Aluminum Concentration In Groundwater: Mathematical Modelling And Laboratory Study, Daria Popugaeva
Electronic Thesis and Dissertation Repository
The remediation of metal-contaminated natural water bodies is prioritized due to metals toxicity, non-biodegradable properties, and accumulative behaviours leading to the increased incidence of adverse health effects. Current investigation is driven by the existing problem of elevated aluminum concentrations in the groundwater of Khibiny alkaline massif (Kola Peninsula). The prohibitive aluminum level exceeding the accepted standard of 0.20 mg L−1 is described as a serious health concern when the groundwater used for the local water supply. The results of comprehensive field data analysis based on chemometric methods applied to the available monitoring data including 12 groundwater quality parameters are …
