Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 1998.<br>Includes bibliographical references.<br>Soil Vapor Extraction (SVE) and Air Sparging have been used for site remediation for about ten years, but most of the past designs are based on experiences and numerical models. Understanding toward the physical problems is far from complete, and some simplified assumptions used in those models may not be true. In this thesis, we focus our attention on the hydrodynamic problems in SVE and air sparging. In Chapter One some basic concepts related t

Abstract:

Column flotation is commonly employed in the processing and recovery of fine mineral particles due to an increase in flotation selectivity unattainable using conventional flotation methods. Such an increase in selectivity is due to the employment of wash water, minimizing hydraulic entrainment of fine gangue particles, and the presence of quiescent operating conditions assisted by the use of various air sparging technologies. High performance air spargers increase the probability of collision and attachment between air bubbles and particles, thereby improving recovery of fine and coarse minera

Abstract:

Traditional membrane filtration plants for drinking water require uninterrupted electricity for pumps and fouling control, thus making it unsuitable for small/rural communities and developing countries. Gravity driven passive membrane filtration systems can be a possible solution to this problem. Previous studies demonstrated that frequent air sparging is beneficial to maintaining a high permeate flux in passive membrane systems. Previous studies also reported that forward flushing after relaxation is also beneficial to maintaining a high permeate flux. Air sparging is an alternate solution to

Abstract:

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2001.<br>Includes bibliographical references (v. 2, leaves 305-312).<br>The efficiency of an in situ air sparging system is controlled by the extent of contact between injected air and contaminated soil and pore fluid. Characterizing the mechanisms governing air propagation through saturated porous media is therefore critical to the design of an effective cleanup treatment. The objectives of this investigation were thus to identify and to quantify the parameters that affect the advancement of

Abstract:

In order to preserve groundwater resources from contamination by volatile organic compounds and to clean up sites contaminated with the compounds, we should understand fate and transport of contaminants in the subsurface systems and physicochemical processes involving remediation technologies. To enhance our understanding, numerical studies were performed on the following topics: (i) multiphase flow and contaminant transport in subsurface environments; (ii) biological transformations of contaminants; (iii) in-situ air sparging (IAS); and, thermal-enhanced venting (TEV). Among VOCs, trichloroet
