1. Brief introduction of AG4040FM RO membrane element

AG4040FM RO membrane element 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 (1,379kPa) are desired. These elements allow moderate energy savings, and are considered a standard in the industry. AG4040FF High RejectionBrackish Water elements feature a FRP outerwrap and 27 mil feed spacers. This element is designed with male end connections.
