Industrial Brackish Water RO
OV-L low-pressure RO membrane elements.
OV-L aromatic polyamide thin-film composite elements are designed for medium- and low-salinity brackish water. The series combines high rejection and high productivity for municipal supply, industrial process water and boiler make-up systems.
Product Advantages
Designed around the application.
- Up to 99.8% stabilized rejection
- 4040 and 8040 configurations
- High-flow 400 and 440 ft2 options
- Wide cleaning pH range
Typical Applications
- Municipal water supply
- Boiler make-up water
- Food and beverage process water
- Textile, electroplating and chemical industries
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.
