About the instructors:

Harley Schreiber graduated from the University of Alberta in 1986 with a B. Sc. degree in Chemical Engineering. In addition to his plant experience, he has worked for 15 years with WesTech and EIMCO, two leading equipment manufacturers in sedimentation and filtration. In this time his efforts have been concentrated on the study of sedimentation equipment through a combination of laboratory testing, plant operation, and product management. His experience also includes involvement in the development of the relatively new sedimentation technologies of Ultra-High Rate and Paste Thickening.

Charles (Chuck) Eddy Silverblatt graduated in 1952 from Northwestern University with a BS and MS in Chemical Engineering. Throughout his entire career he actively participated in, and managed, the technical development of equipment in the fields of filtration and sedimentation. Experience has been both domestic and international over most of the period. He was the co-author of the sedimentation and filtration sections of the Perry’s Chemical Engineering Handbook. He is currently with WesTech Engineering, Inc., Salt Lake City, Utah.
