 RE8040-BLN

Normal low pressure grade RO membrane element for brackish water

 

Product Specifications

  • Permeate Flow rate : 12,000 GPD (45.4 m3/day)
  • Stabilized Salt Rejection : 99.2 %
  • Effective Membrane Area : 400 ft2 (37.2 m2)

Product Description

  • Membrane Type : Thin-film Composite
  • Membrane Material : PA (Polyamide)
  • Membrane Surface Charge : Negative
  • Element Configuration : Spiral-Wound, FRP wrapping

 

Features

  • CSM low pressure BLN elements have similar capabilities to the brackish water membrane at low pressure condition, which can reduce the energy cost and capital costs for the high pressure pumps, plumbing and the pressure vessels.
  • Salt rejection and specific permeate flux of BLN are between BLR and BLF products.
