8”x40” Low Energy Membrane

9,200 gpd / 99.5% / 400 ft²

Recommended where low energy consumption is an important consideration

 


Lewabrane RO B400 LE, 8”x40” Low Energy (Low Pressure) Brackish Water Membrane

The Lewabrane RO B400 LE Low Energy (LE type) membrane elements are recommended for low salinity applications or in applications where low energy consumption is an important consideration. The Lewabrane RO B400 LE elements are designed with a highly efficient polyamide membrane barrier layer, providing high flow productivity combined with excellent salt rejection. Since LE elements in general tend to have a higher fouling tendency from their higher productivity, the Lewabrane RO B400 LE elements are offered with a 0.86 mm (34 mil) feed spacer to reduce the fouling and to improve the cleanability. The LE membrane products are based on a 150 PSI (10.3 bar) test pressure. Typical applications for the RO B400 LE-type of membrane are the treatment of surface water, the pretreatment in front of an ion exchange system, or in the second.
