Reverse Osmosis covers the developments, specifically the Japanese activities in the field of reverse osmosis. This book is composed of five parts encompassing 15 chapters that consider the membranes constituting the important component of each reverse osmosis plant. The first parts treat the different kinds of reverse osmosis modules, including array of the semipermeable membranes. The next part deals with process and plant design. Another part focuses on the reverse osmosis applications, including the production of potable water and industrial water, advanced wastewater treatment, and mass separations in the industry. The last part looks into the accessories and auxiliary operations in reverse osmosis. This book will prove useful to practicing and design engineers and researchers.
