NAPL Removal Surfactants, Foams, and Microemulsions

By C. H. Ward Copyright 2000

    Complete and quantitative, NAPL Removal: Surfactants, Foams, and Microemulsions, belongs to a ten-monograph series that records the results of the Department of Defense/Advanced Applied Technology Demonstration Facility environmental technology demonstrations. It presents the outcome of field demonstrations of innovative in situ remediation technologies.
    In situ surfactant and cosolvent flushing for nonaqueous phase liquids constitutes a technique with the potential to reduce the mass of NAPL - a continuing source of groundwater contamination. This monograph details two technologies - surfactant/foam and single-phase microemulsion - selected for their potential to address the needed breakthroughs.
    Copiously illustrated with figures and tables, NAPL Removal: Surfactants, Foams, and Microemulsions takes you through the entire field demonstration step-by-step. It describes the development of the processes, analyzes the costs, discusses design issues, and covers performance and potential application.
