Desal AG4040TF Brackish Water Desalination Reverse Osmosis, High Rejection[Aug. 13, 2009 11:49:31]
Specification
AG4040TF
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. AG4040TF High Rejection Brackish Water elements feature a tape outerwrap and 28 mil feed spacers. This element is designed with male end connections.
