Industrial Fouling-resistant RO
OV-FR anti-fouling RO membrane elements.
OV-FR elements use a specially treated hydrophilic membrane surface and a 34 mil feed spacer to reduce colloidal and organic fouling, improve cleanability and support stable operation on challenging feed water.
Product Advantages
Designed around the application.
- Hydrophilic surface treatment
- 34 mil feed spacer
- Improved cleaning recovery
- Feed-water salinity up to approximately 10,000 ppm
Typical Applications
- Industrial wastewater reuse
- Municipal and surface water
- Lightly contaminated water sources
- Power and chemical process water
Typical Properties
Model performance data.
Values are based on the defined test conditions below. Actual system performance depends on feed-water quality, pressure, temperature, recovery and pretreatment.
