Brief Introduction
BW reverse osmosis membranes are designed to provide high salt rejection at a standard operating pressure of 225psi for tap water, surface water, groundwater and municipal water applications.
Brackish water membranes are superior to low pressure elements, providing better salt rejection but requiring more operating energy.
