SWRO 8040 고거부 RO 멤브레인

This SWRO 8040 RO membrane is engineered for first-pass seawater desalination, combining high salt rejection with stable flux under standard SWRO test conditions.

This 8.0″ × 40″ thin-film composite (TFC) RO membrane is built for industrial and municipal seawater lines that need high rejection, predictable flux, and compatibility with standard 8040 pressure vessels and interconnectors. It integrates cleanability and preservation guidance so operators can maintain stable product water over the service life.

Key features

• High salt rejection (typical up to 99.7%) for low product conductivity.
• Optimized feed spacer for stable differential pressure and cleaning recovery.
• 1.125″ permeate tube ID; drop-in fit for standard 8040 vessels and couplers.
• Works with staged arrays and energy recovery devices in SWRO trains.
• Supported by approved CIP chemistry 그리고 preservation procedures.

Interfaces & compatibility

• Format: 8040 TFC polyamide element
• Permeate tube: 1.125″ (28.6 mm)
• Vessels/couplers: standard 8″ multi-element pressure vessels with interconnectors
• Change-out: replace like-for-like in most 8040 housings

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 the datasheet explicitly allows; dechlorinate upstream

*Always verify the exact limits on the current model datasheet.

Typical test conditions

32,000 mg/L NaCl, 25 °C, ~800 psi, ~8% recovery. In service, performance varies with temperature, salinity, recovery, and pretreatment (SDI/MFI, antiscalant window).
