Standard Rejection Brackish Water RO Elements -AG8040F-400 #3032518


The A-Series, family of proprietary thin-film reverse osmosis membrane elements, are characterized by high flux and high sodium chloride rejection. AG Standard Brackish Water Elements are selected when high rejection and operating pressures as low as 200 psi (1,379 kPa) are desired. These elements allow moderate energy savings, and are considered a standard in the industry.
