SWRO 8040 Energiezuinig RO-membraan
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.
Product Beschrijving
This 8.0″ × 40″ thin-film composite (TFC) RO-membraan is ontworpen voor 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)

Voordeel één
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.Voordeel TWEE
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.Verwante producten

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.
