Ultra-low pressure RO membranes: an analysis of performance and cost

A new generation of reverse osmosis (RO) membrane has recently been introduced, which is receiving a great deal of interest. This is especially true among application of RO for large-scale municipal desalination systems. This new group of RO membranes operates at very low applied pressure, often in...

Description
Summary:A new generation of reverse osmosis (RO) membrane has recently been introduced, which is receiving a great deal of interest. This is especially true among application of RO for large-scale municipal desalination systems. This new group of RO membranes operates at very low applied pressure, often in the range of 7–10 bar (100–150 psi). This paper presents information and data on the characteristics and performance of these membranes relative to the traditional brackish RO membranes. Performance and cost comparisons are provided. Also, an existing large-scale facility is reviewed.
