SWRO 8040 Energiesparende RO-Membran

Dieser 8,0″ × 40″ Dünnschicht-Verbundstoff (TFC) RO-Membran is designed for Meerwasser systems that prioritize energy efficiency without compromising stable permeate quality. It is a drop-in replacement for standard 8040 pressure vessels and interconnectors, and includes clear operating limits, cleaning chemistry windows, and preservation guidance for dependable service life.

Wesentliche Merkmale

• Low-energy design achieves target flux at reduced feed pressure to help lower kWh per m³.
• Typical salt rejection up to 99.5% for dependable product conductivity.
• Balanced feed spacers support stable differential pressure and effective CIP.
• 1.125″ permeate tube ID; drop-in fit for multi-element 8040 Gefäße und Kupplungen.
• Compatible with energy recovery devices (ERD) and staged SWRO arrays.

Schnittstellen und Kompatibilität

• Format: 8040 TFC-Polyamid-Element
• Permeatrohr: 1,125″ (28,6 mm)
• Housings/couplers: standard 8″ pressure vessels with interconnectors
• Change-out: replace like-for-like in most 8040 trains

Betriebs- und Reinigungsgrenzen*

• Maximale Temperatur: 45 °C (113 °F)
• pH-Bereich (Betrieb): 2-11(Reinigung): 1-12
• Maximaler Druck: 1.200 psi (8,3 MPa)
• Freies Chlor: nicht empfohlen on TFC unless explicitly allowed by the datasheet; dechlorinate upstream

*Always verify final limits on the current model datasheet.

Typische Testbedingungen

32.000 mg/L NaCl, 25 °C, reduced operating pressure versus HR types, and ~8% Wiederherstellung. In service, performance depends on temperature, salinity, recovery, and pretreatment (SDI/MFI, antiscalant window).

What’s included

• Werkskonserviertes Element im versiegelten Beutel
• Installation torque notes; cleaning & preservation guidance (download)
