SWRO 8040 Low-Energy RO Membrane
SWRO 8040 low-energy seawater reverse osmosis membrane engineered to deliver similar productivity at lower operating pressure. Rated around 32,000 mg/L NaCl at 25 °C. Typical salt rejection up to 99.5% with a standard 1.125″ permeate tube for 8″ vessels.
Deskripsi Produk
This 8.0″ × 40″ thin-film composite (TFC) Membran RO is designed for seawater 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.
Key features
- 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 vessels and couplers.
- Compatible with energy recovery devices (ERD) and staged SWRO arrays.
Interfaces & compatibility
- Format: 8040 TFC polyamide element
- Permeate tube: 1.125″ (28.6 mm)
- Housings/couplers: standard 8″ pressure vessels with interconnectors
- Change-out: replace like-for-like in most 8040 trains
Operating & cleaning limits*
- Max temperature: 45 °C (113 °F)
- pH range (operation): 2–11; (cleaning): 1–12
- Max pressure: 1,200 psi (8.3 MPa)
- Free chlorine: not recommended on TFC unless explicitly allowed by the datasheet; dechlorinate upstream
*Always verify final limits on the current model datasheet.
Typical test conditions
32,000 mg/L NaCl, 25 °C, reduced operating pressure versus HR types, and ~8% recovery. In service, performance depends on temperature, salinity, recovery, and pretreatment (SDI/MFI, antiscalant window).
What’s included
- Factory-preserved element in sealed bag
- Installation torque notes; cleaning & preservation guidance (download)

Keuntungan Satu
Advantage 1 — Lower pressure for the same output
The low-energy design helps achieve target flux at reduced feed pressure, supporting lower specific energy consumption and potentially extending high-pressure pump life when operated within recommended windows.Keuntungan DUA
Advantage 2 — Drop-in 8040 compatibility
Standard 1.125″ permeate tube and multi-element vessel coupling enable quick change-outs. Acceptance after start-up is straightforward: normalized permeate flow near the clean baseline, rejection on spec, and stage ΔP within limits.Produk Terkait
