The Affordable Desalination Collaboration (ADC) is working to make seawater desalination using reverse osmosis (SWRO) more energy efficient and more cost effective. One objective of the ADC is to provide a platform by which cutting edge technologies can be tested and measured for their ability to reduce the overall cost of the SWRO treatment proce...

There are new kinds of flow schemes that can reduce the cost of higher recovery seawater and brackish water systems. Under normal operating conditions, there is minimal mixing from the concentrate to the feed flow streams. This concept involves decreasing the low pressure system feed flow while maintaining the high pressure concentrate flow through...

This presentation is the results of the Affordable Desalination Collaboration testing. The testing demonstrated desalination of graater than 50% and as high as 65% was possible. A variety of membrane elements and treatment schemes were evaluated....
