This paper provides an innovative detailed design approach to right inadequate design, control features and deteriorating wells while optimizing performance from Reverse Osmosis Membranes....

This presentation discusses prgrammable logic controllers, input and output modules, central processor, and the steps required to program. Examples of screenshots are given, sillustrating the programming steps....

Paper chronicles the City of Port St. Lucie?s 2011 Reverse Osmosis membrane replacement process which included significant pilot testing. Piloting was conducted to achieve chemical reduction, process optimization, energy reduction and improved water quality. The result of this work ultimately resulted in a reduction in treatment cost of $0.06 per t...

Based on over pumping, saltwater intrusion, or contamination from nutrient loading, studies are indicating that aquifers in these states are being taxed to unsustainable levels. Utilities then must find new treatment methods or alternative sources of water such as brackish or seawater. The public perception that Desalination is expensive though is ...

The presentation will look at reuse with the focus of identifying what factors influence the utility's decisions to proceed with reuse. A historic look at the early features of reuse will highlight municipalities across the nation whom have integrated reuse into their utility offerings, credits gained from the integration of reuse into their utlit...

Port St. Lucie’s James E Anderson RO Facility is a 22.5 MGD treatment plant that has been in service since 2005. The facility is in need of membrane replacements and is currently undergoing a pilot testing effort to verify acceptable membrane elements. In addition to traditional configuration testing, the pilot efforts include an alternative flow...

Energy recovery technologies such as the pressure exchanger (PX), have previously focused on seawater RO applications due to the rather quick payback. This leaves brackish water RO (BWRO) facilities to turbochargers that yield less efficient transfer of energy than their PX counterparts. Recently, the first municipal BRWO application of a PX energy...
