Low Energy Tap Water Thin Film Reverse Osmosis Membranes

Low Energy RO Membrane Elements in all sizes are now available from AMI. These reverse osmosis membranes are specially designed to produce the same product flow as the earlier models, but at a lower pressure. By using these instead of standard elements, you can significantly reduce your operating costs.

Note:

Performance specifications based on, 2000 mg/l sodium chloride, 150 psi (1.08 MPa) applied pressure, 77°F (25°C) feed water temperature, pH 8 and 10% recovery. Element permeate flow may vary -15%/+25%. Low energy membranes in all sizes are now available from AMI. These membranes produce the same product flow as the earlier models but at a lower pressure (about 50-60% lower). 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.
