Lewabrane RO B400 ULP ASD, 8”x40” Ultra Low Pressure & Reduced Fouling Tendency 8040 Membrane

Lanxess ULP 8040 elements are offered with a 0.86 mm (34 mil) feed spacer to reduce the fouling and to improve the cleanability.

Lewabrane ULP 8040 membranes are based on a 7.6 bar (110 PSI) test pressure.

Extra low pressure XLP membrane is suitable for water purification applications of water sources with salt concentration lower than 1000 ppm.

The Lewabrane® spiral wound reverse osmosis (RO) 8040 membrane RO B400 ULP ASD has a highly permeable composite polyamide (PA) membrane. It is designed for low salinity water to operate at ultra low pressure (ULP). The high permeability results in up to 40% lower energy consumption compared to standard elements like the RO B400 HR. The ASD ( Alternating Strand Design) feed spacer offers a lower fouling tendency to improve the RO lifetime cost performance.
The 8040 ULP Membranes are characterized by
• High rejection of organic compounds
• Low energy demand
• Low fouling tendency due to ASD feed spacer.

Salt Rejection: 99.5%.*

Permeate Flow: 10,200 gpd (38.6 m³/day).*

Membrane Area: 400 ft².

Diameter/Length: 8 inch / 40 inch.

Feed Spacer Thickness: 34 mil (ASD Spacer).

*Test conditions: 500 mg/l NaCl, 7.6 bar (110 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).

Made by Lanxess Germany.
