Full Description

This powerpoint presentation provides new insights into lead and copper corrosion control and treatment change impacts. Topics covered include: importance of ORP/oxidants in corrosion anddeposition;aging behavior of Pb vs Cu pipes;PbOsub2/sub occurrence and implications;optimizing orthophosphate dosage factors;dissimilar scale materials on Pb surfaces; and,five treatment implementation/change areasto watch. They include: small system with multiple contaminants (U, As,Rn) using anion-exchange;disinfection of high ammonia groundwater;addition of oxygen or chlorine to high alkalinitygroundwater with low natural ORP;lime softening versus IX and membrane softening; and,overdosing of polyphosphate to prevent post-depositionof calcium carbonate.
