Lewabrane RO B085 FR 4040, 4”x40” Fouling Resistant Reverse Osmosis Membrane
Lewabrane RO B085 FR 4040 RO membranes provide the highest productivity and high salt rejection.
Lewabrane RO B085 FR 4040 Fouling resistant (FR-type) elements are designed for water with a higher organic or biological fouling rate.
In addition to the low-charged membrane, which provides a lower fouling rate, the Lewabrane RO B085 FR 4040 elements have with a 0.86 mm (34 mil) feed spacer a thicker feed channel, allowing improved movement of solutes and particles through the feed channel and enhancing the cleanability of the element. The thicker feed channel also results in a lower pressure drop through the RO membrane element.
Salt Rejection: 99.5%.
Permeate Flow: 2,400 gpd (8.9 m³/day).
Membrane Area: 85 ft².
Diameter/Length: 4 / 40 inch.
Feed Spacer Thickness: 34 mil.
*Test conditions: TDS 2,000 mg/l NaCl, 15.5 bar (225 psi), 25 °C (77 °F), pH 7, recovery rate 15%.
*Pre-treatment must be used to protect the membrane (softener, antiscalant dosing pump, sand filter, carbon filter, 5 mic cartridge fitler …etc).
