  • Dow Filmtec BW30-4040 Brackish Water Industrial Reverse Osmosis Membrane:
  • 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.
  • Dow Filmtec Part # 80783

  • Dow Filmtec BW30-4040 Brackish Water Reverse Osmosis Systems:
  • The Dow Filmtec BW30-4040 Reverse Osmosis Membrane can be used in many brands of industrial Reverse Osmosis Water Filtration Systems.
  • Dow Filmtec BW30-4040 Brackish Water RO System Accessories:
  • Use a TDS Meter to monitor the Total Dissolved Solids before and after the Filmtec BW30-4040 Industrial Reverse Osmosis Membrane.
  • Use a Digital RO Tank Pressure Gauge to monitor the Reverse Osmosis Tank Pressure.
  • Filmtec Dow BW30-4040 Reverse Osmosis Membrane Instructions:
  • 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.
  • Keep the BW30-4040 RO element moist at all times after initial wetting.
  • 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.
  • 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.
  • 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 50 psi (3.4 bar).
