AG LF Series
Low Fouling Brackish Water Reverse Osmosis Elements
The A-Series LF proprietary thin-film reverse osmo-
sis (RO) membrane elements are characterized by
high flow, high sodium chloride rejection and low
fouling surface properties. AG LF brackish water
elements are selected when high rejection and op-
erating pressures as low as 200 psi (1,379 kPa) are
desired. These elements are recommended for
brackish water with salt concentration (TDS) levels
between 1,000 and 10,000mg/l or when very high
salt rejection of monovalent ions is required.
AG LF high rejection brackish water elements fea-
ture a Fiberglass outer wrap.
