SWRO 8040 高透過率RO膜

SWRO 8040 high-rejection seawater reverse osmosis membrane for first-pass desalination. Rated around 32,000 mg/L NaCl at 25 °C with typical operating pressure near 800 psi. Typical salt rejection up to 99.7% when pretreatment, recovery, and temperature follow supplier limits.

商品説明

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膜 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 そして 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 NaCl25 °C~800 psi~8% recovery. In service, performance varies with temperature, salinity, recovery, and pretreatment (SDI/MFI, antiscalant window).

適用業種

  • Seawater desalination (first-pass SWRO) for municipalities
  • Coastal hotels, island resorts, marine/offshore watermakers
  • Industrial process water where seawater feed requires high rejection

アドバンテージ・ワン

Advantage 1 — High rejection for stable product water

Deliver consistently low product conductivity with robust polyamide selectivity and flow-balanced feed spacers that help control differential pressure across stages.

アドバンテージ2

Advantage 2 — Drop-in 8040 compatibility and serviceability

スタンダード 1.125″ permeate tube and multi-element vessel coupling enable fast change-outs in existing housings. Supported by clear acceptance criteria after start-up: normalized permeate flow ≥ 90–100% of the clean baseline, rejection at spec, and stage ΔP within limits.
