Extra-Low Energy (XLE) Reverse Osmosis Membranes

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

Note:

Performance specifications based on, 2000 mg/l sodium chloride, 100 psi 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 similar product flow as the earlier models but at a lower pressure. 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.E
