Ultrafiltration Membranes and Applications

This book is a record of a symposium, "Ultrafiltration Membranes and Applications," which was held at the l78th National Meeting of the American Chemical Society in Washington, D.C., September 11-13, 1979.

In organlzlng these sessions, I hoped to provide a comprehensive survey of the current state of ultrafiltration theory, the most recent advances in membrane technology, and a thorough treatment of existing applications and future directions for ultrafiltration.

For me, the symposium was an outstanding success. It was a truly international forum with stimulating presentations and an enthusiastic audience.

I hope that some of this spirit has spilled over into this volume, which is intended to reach a much wider audience.

I am indebted to the Division of Colloid and Surface Chemistry of the American Chemical Society for their sponsorship.
