Effective removal of non-aqueous phase liquid pools in groundwater and volatile organic compounds (VOCs) from contaminated soils can be achieved by surfactant flushing. This surfactant-rich ground water contains VOCs like trichloroethylene (TCE), dichloroethylene (DCE), etc. Membrane pervaporation technique is employed here to remove TCE from these micellar systems where a very high percentage of the VOC is trapped inside the micellar core. The micellar solution flows through the bore of microporous hydrophobic hollow fibers wherein the micelles break down and release the surfactants and the TCE. The TCE is then removed through the pores and a nonporous thin silicone skin on the outside surface of the fiber, the other side of which is subjected to vacuum to allow pervaporation-based removal of the VOC. This research has characterized such a process for removal of TCE with or without surfactant. It was established that the presence of surfactant adversely affected the removal of TCE. The flux of TCE was found to be an increasing function of feed flow rate and Reynolds number. This research has also briefly explored the permeation of nonvolatile hydrocarbons such as dodecane from water flowing through the fiber bore by using a similar hollow fiber membrane.

The Handbook of Membrane Separations: Chemical, Pharmaceutical, and Biotechnological Applications provides detailed information on membrane separation technologies as they have evolved over the past decades. To provide a basic understanding of membrane technology, this book documents the developments dealing with these technologies. It explores chemical, pharmaceutical, food processing and biotechnological applications of membrane processes ranging from selective separation to solvent and material recovery. This text also presents in-depth knowledge of membrane separation mechanisms, transport models, membrane permeability computations, membrane types and modules, as well as membrane reactors.

This book edition on "Wastewater Management and Technologies" brings together a wealth of expertise by the authors, who exemplify the wide range of options available—from nature-based solutions to different levels of technology—and the different experiences through case studies from around the world, with a particular focus on conditions in developing countries. The book is part of a book series (special editions) based on the publication of the book "Water and Wastewater Management", published by Springer in 2022 (ISBN 978-3-030-9528-7). The part about "Wastewater Management and Technologies" edited in this book will be deepened with this first special edition in terms of technological topics.
