The Filmtec XLE-4040 commercial reverse osmosis membrane offers better system performance consistently and more economically. Be sure to keep the membrane moist after initial use, for long-lasting use and reliability.
Instructions
- After installation of the Filmtec XLE-4040, the first full tank of permeate should be discarded. Do not use this initial permeate
- Proper start-up of reverse osmosis water treatment system is essential to prepare the XLE-4040 industrial membrane elements for operating service and to prevent membrane damage due to overfeeding or hydraulic shock
- Keep the XLE-4040 RO element moist at all times after initial wetting. During prolonged system shutdowns, it is recommended that the Filmtec Dow XLE-4040 membrane elements be immersed in a preservative solution. This is to prevent biological growth
- Avoid any abrupt pressure or cross-flow variations on the spiral elements during shutdown, cleaning or other sequences to prevent possible XLE-4040 Reverse Osmosis Membrane damage
- During start-up, a gradual change from a standstill to operating state is recommended
- Feed pressure should be increased gradually over a 30-60 second time frame--cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds
- Permeate obtained from first hour of operation should be discarded
- Maximum pressure drop across an entire pressure vessel (housing) is 30 psi (2.1 bar)
