Reverse Osmosis Membranes - AG HR LF Series

High Rejection, Low Fouling Reverse Osmosis Elements for Brackish Water

The thin-film composite reverse osmosis membranes of the A series feature high flow and high rejection of sodium chloride. The AG HR LF elements for brackish water are selected when high rejection rates and operating pressures of about 200 psi (1379 kPa) are needed. These elements are recommended for brackish water with a salt concentration (TDS) between 1000 and 10000 mg/l or when very high rejection of monovalent ion salts is required.
The AG HR LF high rejection, low fouling elements for brackish water have an outer fiberglass shell and male or female end connections.
