Zebra Mussel Research Technical Notes. Design of an In-Line Backwash Filtration

摘要

The U.S. Army Engineer District, Nashville (CELRN), plans to install an in-lineautomatic backwash filtration system at Barkley Dam powerhouse on the Cumberland River (river mile 30.6) located in Livingston and Lyon Counties, Kentucky. Barkley's powerhouse has four low-head generating units cooled by pumped water. The purpose of the filtration system is to guard against an expected zebra mussel (Dreissena polymorpha) infestation by removing from the cooling water system stages of this organism that are capable of settling and attaching. This technical note describes the planning and design of the Barkley system.
