The Lewabrane® RO B400 FR ASD are spiral wound, composite polyamide (PA) membrane elements designed to be used for brackish water reverse osmosis (BWRO) applications with a high tendency of biological or organic fouling. The ASD (Alternating Strand Design) feed spacer technology offers an improvement in RO lifetime cost performance by lower pressure drop and reduced fouling tendency. Lewabrane® RO B400 FR ASD elements are characterized by

  • High cross-linked PA membrane chemistry
  • Excellent rejection performance combined with good permeate flow
  • ASD feed spacer technology inside
Product Group: Fouling Resistant
Permeate flow rate: 41.5 m³/day (11,000 gpd)
Salt rejection: 99.7%
