More About This Title Reverse Osmosis: Industrial Processes and Applications, Second Edition

English

This new edition of the bestselling Reverse Osmosis is the most comprehensive and up-to-date coverage of the process of reverse osmosis in industrial applications, a technology that is becoming increasingly more important as more and more companies choose to “go green.”  This book covers all of the processes and equipment necessary to design, operate, and troubleshoot reverse osmosis systems, from the fundamental principles of reverse osmosis technology and membranes to the much more advanced engineering principles necessary for designing a reverse osmosis system. 

 

The second edition is an enhanced version of the original best seller.  Each chapter has been reviewed and updated.  Revised features include more detail on various pretreatment techniques such as greensand and pyrolusite pretreatment media.  The design projection chapter has been edited to include up-to-date information on current projection programs.  A new section on microbial fouling control featuring chlorine and alternative techniques is included to address the needs of most RO systems.  Also, a discussion on forward osmosis is added as an alternative and/or companion technology to reverse osmosis for water treatment.  The second edition includes all updated, basic, in-depth information for design, operation, and optimization of reverse osmosis systems.    

 

Earlier chapters cover the basic principles, the history of reverse osmosis, basic terms and definitions, and essential equipment.  The book then goes into pretreatment processes and system design, then, finally, operations and troubleshooting.  The author includes a section on the impact of other membrane technologies and even includes a “Frequently Asked Questions” chapter.

Jane Kucera is a chemical engineer with 25 years' experience in the area of membrane technology. Jane began her work with membranes in the Seawater Laboratory at UCLA where she received her Master of Chemical Engineering degree in 1984. She worked for 7 years with Bend Research, where she worked on water re-use systems for the International Space Station.? Ms. Kucera's subsequent career path is a "who's who" of the world's most respected companies working in water treatment, including GE and Siemens. She joined the Nalco Company in 2003, where she is a senior engineer with a variety of responsibilities. She has approximately 40 publications to her credit, including journal articles, presentations, and book chapters.
