Description
The Hydranautics SWC5-LD Membrane is a low-fouling, 8-inch seawater reverse osmosis element built for desalination plants that run on open sea intakes and beach wells. Hydranautics SWC elements treat more than 1.7 million m³ of seawater every day worldwide, and the LD (low differential) design keeps pressure drop low as the feed spacer collects less fouling.
Plant operators in Oman choose this element because Gulf of Oman and Arabian Sea feed water is warm, high in TDS and prone to biofouling. A lower-fouling membrane means longer intervals between chemical cleans, steadier permeate flow and lower energy cost per cubic metre.
Hydranautics SWC5-LD Membrane – Key Features
- Low differential pressure (LD) feed spacer that resists fouling and makes cleaning easier
- High salt rejection for seawater feeds up to about 45,000 mg/L TDS
- Composite polyamide chemistry with stable rejection over a long service life
- Standard 8-inch x 40-inch size, a drop-in replacement for most SWRO pressure vessels
- Suited to warm feed water typical of Omani coastal intakes
- Works with standard antiscalant and CIP chemical programmes

Where to Use the Hydranautics SWC5-LD Membrane in Oman
Use the Hydranautics SWC5-LD Membrane in hotel and resort desalination units, island and coastal camps, ship and offshore platform watermakers, industrial process water plants in Sohar and Duqm, and municipal or containerized SWRO plants. It is also a good upgrade when an older seawater element shows rising differential pressure or falling permeate quality.
Why Buy the Hydranautics SWC5-LD Membrane from UV Water Systems
UV Water Systems (Uniqueness View LLC) has supplied water treatment equipment in Oman for more than 14 years. We are ISO 9001:2015 certified and work with homes, restaurants, hospitals, schools, oil and gas sites and government projects. Before we recommend the Hydranautics SWC5-LD Membrane, we test your feed water for TDS, hardness, chlorine and pH, so the system you buy matches your real water conditions.
Browse more equipment in our water treatment shop or read guides on the UV Water Systems blog. For drinking water quality limits, see the Hydranautics membrane product information.
Installation, Service and Spare Parts
We supply the element with a membrane loading service, pressure vessel inspection and a performance check after start-up. If your plant needs a membrane clean before replacement, we can carry out CIP with acidic and alkaline cleaners from our chemical range. Our field team covers Muscat, Al Khuwair, Ruwi, Al Hail, Seeb and Barka daily, and we offer annual maintenance contracts (AMC) for regular filter changes and performance checks.
FAQs about the Hydranautics SWC5-LD Membrane
How long does the Hydranautics SWC5-LD Membrane last?
With good pre-treatment (SDI below 3), correct antiscalant dosing and regular cleaning, a seawater element typically lasts 3 to 5 years in Omani conditions.
Do you deliver and install the Hydranautics SWC5-LD Membrane outside Muscat?
Yes. UV Water Systems delivers across Oman, including Sohar, Nizwa, Sur, Salalah and Ibri. Our technicians handle installation, commissioning and water testing on site.
