Description
The Industrial RO Membrane 8040 is a full-size 8-inch by 40-inch spiral-wound reverse osmosis element used in commercial and industrial RO plants. It is the standard building block of plants producing anything from a few cubic metres to hundreds of cubic metres per day, for hotels, hospitals, factories, farms, bottling plants and municipal schemes across Oman.
We supply 8040 elements from leading manufacturers, with Dupont Filmtec as our preferred brand, for both new plants and membrane replacement projects.
Applications
- Brackish well water desalination for farms, camps and industry
- Commercial RO plants for hotels, hospitals and schools
- Boiler feed, cooling and process water
- Food and beverage and bottled water production
- Pre-treatment for DI and EDI polishing systems
Key features
- Thin-film composite polyamide, spiral-wound construction
- Standard 8″ x 40″ size fits 8040 pressure vessels
- High active membrane area (typically around 400 ft² / 37 m²)
- High stabilised salt rejection, typically 99%+ at test conditions
- Fouling-resistant and low-energy variants available
Typical specifications
| Size | 8 inch x 40 inch |
| Type | Brackish water RO (BW), TFC polyamide |
| Typical permeate flow | Approx. 9,000–11,500 GPD at test conditions (model dependent) |
| Max operating pressure | Approx. 41 bar (600 psi) |
| Max feed temperature | 45 °C |
| Free chlorine tolerance | Below 0.1 ppm |
Exact flow, rejection and test conditions depend on the brand and model. We provide the manufacturer datasheet with every quotation.
Choosing the right 8040 element
Feed water in Oman ranges from low-TDS network water to wells above 5,000 ppm, often with high silica, iron or hardness. The right Industrial RO Membrane 8040 depends on feed TDS, temperature, recovery target and fouling risk. We review your water analysis, run projections with the manufacturer design software and recommend the element type and array. For seawater, a seawater (SW) element is required instead. See our RO membranes range and commercial and industrial RO plants.
Membrane replacement and cleaning
Most 8040 elements last 3 to 5 years with good pre-treatment and regular cleaning. When normalised permeate flow drops by 10–15%, or differential pressure rises, a clean-in-place (CIP) is due. Farz Water offers membrane replacement, CIP and plant servicing. For background on RO, see Wikipedia.
