PLT 2540 NP

Summary

Product identification

This summary covers the TRISEP® PLT 2540 NP Elements, dated 06/01/2022. These elements feature NADIR® NP polyethersulfone (PES) membranes, which exhibit nanofiltration properties after a high-pressure (40 bar) stabilization, offering unique separation characteristics for process applications.

Available Models:

• TRISEP® PLT 2540-NP010-31
• TRISEP® PLT 2540-NP030-31

Membrane Characteristics:

• Membrane Type: Polyethersulfone (PES)
• Nominal M.W.C.O.:
  • NADIR® NP010: 1,000 – 1,200 Da
  • NADIR® NP030: 500 - 600 Da
• Membrane Area: 1.9 m² (20 ft²) for both models.
• Feed Spacer Thickness: 31 mil for both models.
• Construction: All models include a fiberglass outer wrap, diamond-shaped feed spacers, anti-telescoping devices (ATDs) attached to the ends of the element, and one brine seal.

Operating limits

• Maximum Operating Pressure: 41 bar (600 psi)
• Maximum Operating Temperature: 45°C (113°F)
• Cleaning pH Range: 1.0 – 12.0
• Cleaning Chlorine Tolerance: 200 ppm (sanitization) at pH ≥ 10.5
• Maximum Pressure Drop:
  • 1 bar (15 psi) per element
  • 4 bar (60 psi) per housing

Mechanical / hydraulic

• Element Weight: 3 kg (7 lb) for both models.
• Permeate Tube: Male elements have a protruding permeate tube, indicated as "D" in the diagram, with a dimension of 25.4 mm (1.0 in).
• Physical Dimensions: See the official PDF for exact tabulated values for physical dimensions, as the extract's table was fragmented.

Important Information

• Start-up: MANN+HUMMEL recommends flushing elements for 30 minutes at low pressure and discarding permeate during the flush prior to operation. Refer to "Element Start-Up Guide – System Start-Up (TSG-O-005)" for a detailed procedure.
• Cleaning: TRISEP® membrane elements require periodic cleaning to ensure proper operation and prevent membrane damage. Consult "Membrane Cleaning Guide – Water Application Elements (TSG-C-001)".
• Storage: Proper storage of TRISEP membrane elements is essential to maintain operation and prevent damage. Refer to "Element Storage Guides (TSG-O-009 & TSG-O-010)".
