Joe Mouawad, P.E.
April 28, 2016

2. Background Existing 500c Membranes 500d Membranes
Installed in 2006 and approaching the end of useful life
Increasing frequency of maintenance/repair activities
Superseded by 500d module design
500d Membranes
Support higher membrane integrity testing (MIT) pressures
Will comply with EPA’s LT2 water quality testing standards
Easier to maintain
Investigation and Evaluation of Ancillary Equipment
Investigate abrasive particles in raw water supply (sand and shell fragments)
Identify potential upgrades to mitigate damage
Screens and Reject Recovery Facility
Evaluate products to replace fine screens
Upgrades/modifications to existing blowers, pumps, and piping
Telemetry and programming upgrades
