Scour Velocity on DIP
Scour Velocity on DIP
(OP)
I am designing a Return Activated Sludge (RAS) pipe with cement-lined, ductile iron pipe. Is there a minimum velocity to eliminate the accumulation of solids? Is this infomation published somewhere? ...Thanks.

Lindbergs CERM on page 28-5 states that 1.5 fps will keep mixed liquor solids in suspension, and 2 fps will allow resuspension of settled MLSS.
