    description Instructions
    1. Proper start-up of reverse osmosis water treatment system is essential to prepare the BW30-4040 industrial membrane elements for operating service and to prevent membrane damage due to overfeeding or hydraulic shock
    2. Keep the BW30-4040 RO element moist at all times after initial wetting
    3. During prolonged system shutdowns, it is recommended that the Filmtec BW30-4040 membrane elements be immersed in a preservative solution. This is to prevent biological growth
    4. Avoid any abrupt pressure or cross-flow variations on the spiral elements during shutdown, cleaning or other sequences to prevent possible BW30-4040 Reverse Osmosis Membrane damage
    5. During start-up, a gradual change from a standstill to operating state is recommended
    6. Feed pressure should be increased gradually over a 30-60 second time frame
    7. Cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds
    8. Permeate obtained from first hour of operation should be discarded
    9. Maximum pressure drop across an entire pressure vessel (housing) is 50 psi (3.4 bar)

    The Dow Filmtec BW30-4040 brackish water reverse osmosis membrane elements provide consistent and outstanding system performance in light industrial applications. The Filmtec BW30-4040 features the thickest feed spacer (34 mil) to lessen the impact of fouling. Elements with a hard shell exterior are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops. The Dow Filmtec BW30-4040 industrial RO membrane may be cleaned over the widest pH range (pH 1-13) for the most effective cleaning.
