Since the presence of free chlorine and other oxidizing agents will cause premature membrane failure, a carbon block filter should be used before this RO membrane element when filtering chlorinated water.
Performance specifications based on 500 ppm tap water, 50 psi (0.35 MPa) applied pressure, 77°F (25°C) feed water temperature, feed water pH 7-8 and 15% recovery. Element permeate flow may vary ± 15%.
*Salt Rejection shown is from internal test data.
