Lewabrane® RO S400 HF elements are spiral-wound, composite polyamide membrane elements designed for the desalination of seawater. The S400 HF membrane is characterized by an extremely durable, highly cross-linked polymeric separating layer suitable for high salinity, high pressure applications.

The Lewabrane® RO S400 HF is recommended for single pass and two pass applications (depending on the salinity, temperature, and permeate quality requirement) where stable salt rejection performance over the expected lifetime is an important consideration

Product Group: High Flow
Permeate flow rate: 34,1 m³/day
Salt rejection: 99.8%
