Note: Performance specifications based on 2,000 mg/l sodium chloride, 150 psi (1MPa) applied pressure, 77°F (25°C) feed water temperature, pH 8 and 15% recovery. Element permeate flow may vary ± 20%. A word of Caution: Do not run these membranes at a pressure that will produce more than their rated product flow rate. This will lead to premature fouling of the membrane resulting in drop in permeate flow and higher TDS of the permeate.
