Abstract

This chapter summarizes the findings of different studies on the prevention and elimination of cyanobacterial blooms in raw water resources as well as the removal of cyanotoxins during water treatment with physical processes. Treatments that can be applied at the source water and limit bloom formation include aeration and chemical addition (e.g., copper sulfate and algaecides). Efficiencies of conventional treatment processes such as coagulation, flocculation, sedimentation, filtration, and membrane processes for the removal of both cyanobacteria and cyanotoxins are also discussed. In addition, adsorption of cyanotoxins on activated carbon (AC) and several micro- and nanomaterials is presented. Finally, integrated treatment examples are reported with a specific reference to a lab study on powdered AC-ultrafiltration technologies for the removal of cyanotoxins.

Funding Information:
Professor Dionysios (Dion) Dionysiou was born on the Island of Cyprus. He is currently a professor of Environmental Engineering and Science at the University of Cincinnati. He teaches courses and performs research in the areas of drinking water quality and treatment, advanced unit operations for water treatment, advanced oxidation technologies and nanotechnologies, and physical–chemical processes for water quality control. Dr. Dionysiou is the author or coauthor of more than 240 refereed journal publications, conference proceedings, and book chapters. He has received funding from NSF, US EPA, NASA, NOAA/CICEET, USGS, USDA, and DuPont. He is currently one of the editors of Chemical Engineering Journal, Editor of the Journal of Advanced Oxidation Technologies, and Special Issue Editor of the Journal of Environmental Engineering (ASCE). He is a member of the Editorial Boards of several other journals. Dr. Dionysiou has been featured in several international symposia and professional events, including a recent interview on ‘Cleaning up water’ published on 5 July 2011 in the Chemistry World magazine of the Royal Society of Chemistry.

Funding Information:
Kevin O'Shea is Professor of Chemistry and Biochemistry and the Associate Dean of the University Graduate School at Florida International University. He earned an undergraduate degree with Honors from California State University, Sacramento (1984) and a PhD in Chemistry from the University of California, Los Angeles, CA, USA (1989). His current research interests are focused in the area of the reactions of reactive oxygen species with organic compounds of biological importance and/or environmental significance. The fundamental understanding of the reactions of ROS with natural toxins and pollutants is critical to the development and application of advanced oxidation technologies for water purification. Professor O'Shea's research projects have been funded by a variety of agencies, including the National Science Foundation, the National Institutes of Health, Petroleum Research Fund, Dreyfus Foundation, and the US Environmental Protection Agency. He has published ∼70 peer-reviewed articles and book chapters in the research areas of organic and environmental chemistry.
