EDR Depth pre-filters

Summary

Product identification

The EDR.Z is a depth filter engineered for protecting Electrodialysis Reversal (EDR) membrane components, suitable for use in Veolia’s EDR systems and most other EDR systems.

Features and Benefits:

• 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 ensures no media migration and prevents premature surface blinding.
• Provides lower total cost of filtration operations.
• Z.Plex* technology depth filter for EDR pre-filtration.

Applications

• EDR pre-filtration for Veolia EDR systems and universal systems.

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)

Mechanical / hydraulic

• Ratings: 5, 10 microns (nominal)
• Inner Diameter: 1.1 in (2.5 cm)
• Outer Diameter: 2.5 in (6.4 cm)
• Lengths:
  • 30 in (76.2 cm)
  • 40 in (101.6 cm)
  • Longer lengths up to 70 in may be available upon request.
• Clean Water Flow Rate: See Graph 1 in the official PDF for flow rate based on a 10 in length filter.

Materials of Construction

• Filter Media: Polypropylene
• Adapters: Polypropylene
• Elastomer: Buna, EPDM, Silicone, Viton¹, Santoprene² (flat gasket only)
  • ¹Viton (trademark of The Chemours Company).
  • ²Santoprene (licensed to Advanced Elastomer Systems, L.P.).

Efficiency Information

The EDR.Z filters are available in 5 µm and 10 µm nominal micron ratings.

• Removal Efficiency: See Table 2 in the official PDF for removal efficiency based on a modified ASTM 795 test procedure at 90.0%, 99.0%, and 99.9% efficiencies.
• Nominal-rated filters have a wider distribution of pore sizes and rejected particle sizes compared to absolute-rated filters. The nominal rating is primarily used for comparison across filter families and between manufacturers. Efficiency depends on particle shape, size, composition, application, and testing protocol.

Quality and Certifications

• Manufactured under a quality management system certified to meet ISO 9001 standards.
• Each filter is assigned a lot code for traceability of data and materials.
• Certifications:
  • U.S. FDA 21CFR 177 food contact requirements
  • NSF 61 Criteria
  • ISO 9001 Criteria

Veolia filter cartridges are designed and manufactured for resistance to a wide range of chemical solutions. Chemical compatibility should be carefully verified for each application.

Ordering Information

Ordering information follows a specific format (e.g., EDR.Z 10-40-XX) where placeholders are replaced by desired values. The configuration allows selection for:

• Type: EDR.Z
• Micron Rating (Nominal): 05 (5 µm), 10 (10 µm)
• Cartridge Length: 30 in (76.2 cm), 40 in (101.6 cm), or longer lengths up to 70 in upon request.
• End #1 Adapter: L (Extended Core), X (Standard Plain End - no gasket), Y (Flat Gasket), H (Fin), K (Self Seal Spring), S (Solid End).
• End #2 Adapter: X (Standard Plain End - no gasket), Y (Flat gasket).
• Elastomer Material: B (Buna), E (EPDM), P (Santoprene - flat gasket only), S (Silicone), V (Viton).

See the official PDF for exact tabulated values and ordering codes.
