Autorenporträt

Alice B. Out water has a B.S. in Mechanical Engineering from the University of Vermont (1983) and an M.S. in Technology and Policy from Massachusetts Institute of Technology ( 1987).She worked in residuals management for the Massachusetts Water Resources Authority, which managed the largest wastewater engineering project of the decade: the $6 billion Boston Harbor Clean-Up. As an engineer specializing in minor residuals and innovative technologies for sludge reuse, Ms. Out water was part of the team that planned and implemented the program that shifted 200 dry tons of sludge a day from ocean disposal to beneficial reuse. She has written numerous technical papers on sludge and scum reuse. This book is a practical handbook for the reuse of sludge and minor residuals.
