S440 HR

Description

Lewabrane RO S440 HF, 8”x40” High Rejection Sea Water Membrane

The Lewabrane® RO S440 HR membrane is characterized by an extremely durable, highly cross-linked polymeric separating layer suitable for high salinity, high pressure applications. The Lewabrane® RO S440 HR membrane element is recommended for single pass applications where stable salt rejection performance during the expected operating lifetime is an important consideration.
The Lewabrane RO S440 HR elements were designed for single pass seawater desalination plants where a high rejection is necessary.
Seawater (S) High rejection (HR) membranes provide the highest salt rejection and the best permeate water quality.

Key attributes of the new RO S HR type:
Low salt passage
More stable salt rejection during operating lifetime
High rejection of critical ions

High rejection type (HR) for the best permeate quality
