Ag-90 H

Summary

Product identification

The AG H Series consists of high-performance, very high rejection brackish water Reverse Osmosis (RO) elements. These elements are designed for applications requiring the highest levels of rejection, including ultrapure water production and treating high-pressure boiler feed water.

AG H Series elements utilize Thin-film membrane (TFM), polyamide technology and are NSF/ANSI/CAN 61 certified. They are engineered to deliver differentiated performance in ionic rejection and in the rejection of uncharged or lightly charged species like silica.

Handling and Storage

• Treat RO elements with care; do not drop.
• Each RO element is wet tested. 8-inch diameter elements are preserved in a 1% weight sodium bisulfite solution and vacuum packed. 4-inch diameter elements are packaged with oxygen scavenger packets.
• During storage, avoid freezing and direct sunlight. Temperature should be below 35°C (95°F).
• After installation, keep RO elements wet and use a compatible preservative for storage longer than 7 days.
• During initial start-up, discharge the first permeate to drain for 30 minutes.
• Permeate back pressure should not exceed feed pressure.
• Maintain elements in a clean condition, unfouled by particulate matter, precipitates, or biological growth.
• Consider cleaning if pressure drop increases by 20% or water permeability decreases by 10%. Use only compatible chemicals.
