Opis

Complete and quantitative, NAPL Removal: Surfactants, Foams, and Micro emulsions, 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 out come of field demonstrations of innovative in situ remediation technol ogies. 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 monog raph details two technologies - surfactant/foam and single-phase micro emulsion - selected for their potential to address the needed breakthr oughs. Copiously illustrated with figures and tables, NAPL Removal: Su rfactants, Foams, and Microemulsions takes you through the entire fiel d demonstration step-by-step. It describes the development of the proc esses, analyzes the costs, discusses design issues, and covers perform ance and potential application.
