SWRO.Zs

Summary

Product identification

The SWRO.Z is a Z.Plex technology depth filter engineered specifically for seawater reverse osmosis pretreatment. It is designed to trap particles throughout the media with true graded density for longer filter lifetime. Its melt-bonded exterior ensures no media migration, and it offers very low pressure drop and flow resistance.

Applications:

• Seawater reverse osmosis pre-filtration for Veolia RO systems and universal equipment.

Operating limits

• Maximum pressure drop: 35 psid (2.4 bar) @ 77°F (25°C)
• Recommended change-out pressure drop: 20 psid (1.4 bar) @ 77°F (25°C)

Mechanical / hydraulic

• Ratings: 1, 5 microns (nominal)
• Inner Diameter (nominal): 1.1 in (2.5 cm)
• Outer Diameter:
  • Standard: 2.46 in (6.2 cm)
  • Available upon request: 2.36 in (6.0 cm)
• Lengths:
  • 40 in (101.6 cm)
  • 50 in (127.0 cm)
  • 60 in (152.4 cm)
  • 70 in (177.8 cm)
  • Longer lengths up to 70 in may be available upon request.
• Materials of Construction:
  • Filter Media: Polypropylene
  • Adapters: Polypropylene
  • Elastomer: Buna, EPDM, Silicone, Viton, Santoprene (flat gasket only)
• Efficiency Information:
  • Removal efficiency based on a modified ASTM 795 procedure is provided for 1 µm and 5 µm nominal filters.
  • Efficiency of nominal filters varies by application; absolute-rated filters reject at least 99% of particles of the listed micron size. Nominal-rated filters have a wider distribution of pore sizes and rejected particle sizes.

Certifications

• U.S. FDA 21CFR 177.1520 food contact requirements
• Article 3 of the EU Framework Regulation No. 1935/2004/EC safety requirements
• EU Plastics Regulation No. 10/2011 (may be used as intended in all compliant EU Member states)
• USP class VI-121°C Plastics criteria
• NSF 61 criteria
• ISO 9001 criteria (filters manufactured under a certified quality management system)

Ordering information
