AG8040F-400
Brackish Water Desalination
Reverse Osmosis, High Rejection

 

The A-Series, family of proprietary thin-film reverse osmosis membrane elements are characterized by high flux and excellent sodium chloride rejection. AG High Rejection Brackish Water Elements are selected when high rejection and operating pressures as low as 200 psig (1,379 kPa) are desired. These elements allow moderate energy savings, and are considered a standard in the industry. AG8040F-400 High Rejection Brackish Water elements feature a FRP outerwrap and 27 mil feed spacers. This element is designed with flush end connections.
