Aquaporin-Inside DWRO 4040

Summary

Product identification

The AQUAPORIN INSIDE® DWRO™ 4040 ELEMENT SERIES consists of biomimetic Drinking Water Reverse Osmosis (DWRO™) membrane elements, which derive their unique properties from embedded aquaporin proteins – nature’s water channels. These elements are designed for high water flow and high rejection of harmful pollutants, ensuring safe and healthy drinking water.

They are available in standard configurations, fitting into conventional point-of-use residential or commercial RO systems.

Available Models:

• Aquaporin Inside® DWRO™ 4040
  • Item no.: 40035
  • Element type: Tape wrap, dry
• Aquaporin Inside® DWRO™ 4040XL
  • Item no.: 40053
  • Element type: Tape wrap, dry

Operating limits

• Maximum operating pressure: 20.7 bar (300 psi)
• Maximum feed flow rate: 3.6 m³/h (16 gpm)
• Maximum operating temperature: 45°C (113°F)
• Maximum pressure drop: 0.7 bar (10 psi)
• pH range (operation): 3-10
• pH range (short-term cleaning): 2-11
• Free chlorine tolerance: < 0.1 ppm

Feed water

• Maximum feed water SDI: 5 (15 min)
• Maximum feed water turbidity: 1 NTU
• Removal of residual free chlorine by pretreatment is recommended to prevent premature membrane failure due to oxidation damage.

Individual element permeate flow rate may vary ± 15%. Permeate from the first hour of operation should be discarded and not used for consumption.

Mechanical / hydraulic

The DWRO™ 4040 element series fits standard 4 inch inner diameter pressure vessels.

Dimensions (inches / millimeters):

• A: 40.0 / 1016.0
• B: 1.05 / 26.7
• C: 0.75 / 19.1
• D: 3.95 / 100.3

Additional information

• Storage: Elements contained in boxes must be kept dry at room temperature (7-32°C / 40-95°F) and should not be stored in direct sunlight.
• Post-wetting handling: Keep elements moist at all times after initial wetting.
• Shutdown: To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative solution before use.
