The Water Desalination Research & Development Program Newsletter - No. 11 - Summer 1998

INTRODUCING...

Kevin Price was recently named Program Manager of Reclamation's Water Desalination Research & Development (DesalR&D) Program. Kevin began his desalting research career by building and operating a pilot plant for one of the last OWRT contracts. Later, he joined Reclamation and has worked here for the past 16 years. He has a MS degree in Chemical Engineering from Columbia University, a MBA in Finance from the University of Denver, and a BS in Zoology from Albertson College of Idaho. Before being appointed to this position, Kevin was responsible for Reclamation's Denver water treatment laboratories, its international desalination research program, and its research work in support of the Yuma Desalting Plant. As our readers know, The DesalR&D program is authorized by the Water Desalination Research and Development Act of 1996. For more information about the program, contact Kevin at 303-445-2260, or visit the DesalR&D web site at: http://www.usbr.gov/pmts/water/research/DWPR/.

ANNOUNCING...

The Desalting and Water Treatment Membrane Manual: A Guide to Membranes for Municipal Water Treatment (2nd ed), report #29, is an update of the popular 1991 edition. As in the first edition, MF, UF, NF, RO, and ED are described in a simple, easy to read, format with discussion of the similarities and differences between the membrane processes. Regulations concerning waste disposal have been added. The cleaning section now examines general procedures and philosophy rather than specifics for each manufacturer. The process design section has been simplified and extended to include system design using manufacturer's design software. There are also many new membrane products in the product review section. New membrane configurations and dimensions are evaluated for their effects on overall module performance. The UF and MF product review sections discuss the problems with characterization and comparison of different products. A cost estimation section has been added to help potential users evaluate the cost of alternative design strategies. Future directions in membrane technology are explored as well as the issues and problems that need to be resolved to facilitate intelligent use of membrane separation in the municipal water treatment market.
