Pump Intake and Hydraulic Design Seminars - 3 Part Series - CD Seminar (0.3 CEUs)

Instructors

David Hanna is a graduate of Rensselaer Polytechnic Institute with a M.S. degree in environmental engineering, and a B.S. degree in marine engineering / mechanical from the United States Merchant Marine Academy. Mr. Hanna is an Associate Professor at Ferris State University with faculty responsibilities in the construction management and surveying engineering programs. Mr. Hanna worked for several consulting engineering and construction management firms for eighteen years before joining the faculty at Ferris State University in 1991.Mr. Hanna is a licensed professional engineer in Michigan and Ohio. He has designed numerous pumping stations and pumping systems associated with water and wastewater projects. Sizes of the facilities range from 80 gallons per minute to 30 million gallons per day. His experience includes design, construction administration, construction installation and quality control, and startup of new facilities as well as evaluation and troubleshooting of existing pumping and treatment facilities. Mr. Hanna has served as an Instructor on hydraulics, pumping systems and treatment processes to the New York State Department of Environmental Conservation and the New York State Department of Health with operator training and certification programs. He is a technical reviewer of pumping standards for the Hydraulic Institute and a member of ASCE.

Course Description

Design of pumping stations and pumping systems for water and wastewater treatment facilities has become increasingly demanding due to decreasing project schedules, available project budget, and the variability of pump performance from one manufacturer to another. This three session series is intended to provide engineers, owners, and facility operators with an understanding of several of the complex hydraulic design issues of applying and designing centrifugal pumping systems including cavitation and sump or intake design.

Seminar-On-CD #1
PUMP CAVITATION
This seminar will evaluate the hydraulic conditions leading to pump cavitation and discuss preventative and remedial measures to address cavitating pumps. A design example with typical variations (suction head, suction lift, high temperature water) will be presented.

Seminar-On-CD #2
SUMP AND INTAKE DESIGN
This seminar will evaluate hydraulic design issues in designing pumping station sumps or intakes. The seminar material will refer to the current intake design standard published by the Hydraulic Institute/American National Standards Institute.

Seminar-On-CD #3
TRENCH TYPE WET WELLS
This seminar will introduce the geometric and hydraulic design issues associated with a trench type wet well design, as currently defined and described by the HI/ANSI sump and intake design standard.
