SWRO 8040 Hoge Afgifte RO Membraan
SWRO 8040 Hoge Afgifte RO Membraan
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.
Product Beschrijving
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-membraan 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 en 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).
What’s included and Why choose this SWRO 8040 RO membrane
- Factory-preserved element in sealed bag

FAQ
V1: Hoe lang gaat het omgekeerde osmose systeem mee?
De levensduur van een omgekeerd osmose systeem hangt af van de waterkwaliteit en het onderhoud. Het membraan gaat meestal 2-3 jaar mee, terwijl het systeem zelf meer dan 10 jaar kan meegaan als het goed onderhouden wordt.
V2: Kan het systeem worden aangepast aan verschillende wateromstandigheden?
Ja, al onze systemen zijn volledig aanpasbaar. We analyseren uw waterrapport en toepassingsbehoeften voordat we oplossingen op maat bieden.
V3: Aan welke normen voldoet de apparatuur van STARK?
Onze producten voldoen aan CE, ISO 9001 en kunnen op verzoek worden ontworpen om te voldoen aan specifieke regionale voorschriften of industrienormen.
V4: Wat is de levertijd voor STARK RO-systemen?
Standaardsystemen worden binnen 7-15 dagen verzonden. Voor aangepaste bestellingen kan de levertijd oplopen tot 20-25 dagen, afhankelijk van de complexiteit.
V5: Biedt u technische ondersteuning of begeleiding bij de installatie?
Ja. We bieden volledige technische documentatie, begeleiding op afstand via video en kunnen op verzoek technici internationaal sturen.
V6: Wat is inbegrepen in jullie offerte?
Onze offerte omvat het volledige RO-systeem, het bedieningspaneel, de pompen, de voorbehandelingsunits en alle benodigde appendages. Installatiegereedschap en reserveonderdelen kunnen op verzoek worden meegeleverd.
