EDR Depth pre-filters

Summary

Product identification

The EDR.Z is a Z.Plex* technology depth pre-filter engineered for protecting Electrodialysis Reversal (EDR) membrane components. It is designed for use in Veolia's EDR and most other EDR systems.

Features and Benefits:

• Engineered specifically for EDR membrane protection.
• Minimal potential for filter media release due to unique construction with high-strength polypropylene core.
• Greater contaminant capacity compared to filters with equivalent removal efficiency.
• Melt-blown media traps particles throughout the entire filter of graded density.
• Bonded interior and exterior ensure no media migration and prevent premature surface blinding.
• Provides lower total cost of filtration operations.

Operating limits

• Maximum pressure drop:
  • 60 psid (4.1 bar) @ 77°F (25°C)
  • 35 psid (2.4 bar) @ 120°F (49°C)
• Recommended change-out pressure drop: 35 psid (2.4 bar) @ 77°F (25°C)

Product water

• Removal Ratings (Nominal): 5, 10 microns.
• Efficiency Information: Removal efficiency based on a modified ASTM 795 test procedure, with efficiency of nominal filters varying by application. See the official PDF for exact tabulated values regarding removal efficiency at various percentages (90.0%, 99.0%, 99.9%).
