Thin film nanocomposites were developed for brackish water RO membranes in 2007. Since the release of these TFN membranes the technology has been developed for seawater RO. The use of this method on SWRO membranes can increase flux from the standard 17 gfd to 33 gfd. At an existing plant this will result in either 70% more water produced or a 20% e...

This paper will present system performance and operational data from the retrofit of an existing Caribbean desalination plant that leveraged the enhanced permeability of nanocomposite membranes to decrease water costs via a reduction in energy consumption In addition, the paper will discuss how alternative system configurations address design chal...
