Industrial Brackish Water

225,000 to 600,000 GPD / 757 to 3,407 M3/D

Brackish Water RO Reverse osmosis, also known as hyper filtration, is used to purify water and remove salts and other impurities. It is also capable of rejecting bacteria, sugars, proteins, particles, dyes, and other constituents that have a molecular weight of greater than 150-250 dalton.

How the Membrane System Works

The spiral membrane is constructed of one or more membrane envelopes wound around a perforated central tube. The permeate passes through the membrane into the envelope and spirals inward to the central tube for collection.

Operation Specifications

  • Feed water temperature = 95º F Max.
  • Hydrogen Sulfide must be removed
  • Feed water pressure = 20 to 80 psi
  • Turbidity should be removed
  • Operating pressure: 175 to 250 psi
  • Iron tolerance: 0.05 ppm Max.
  • Feed water TDS: 0-1,000 ppm, or higher as an option
  • Hardness over 1 GPG requires antiscalant dosing
  • pH range: 3-11
  • Units can handle higher TDS by lowering recovery
  • Silica Tolerance: 25 ppm max. @ 60% recover

All specifications are subject to change without notice

Special Note: If the feed water TDS exceeds 1,000 ppm, the system model number changes o BW-XXXK-XXXX, and a suffix is added to the end of the model number. "-3" is added if the TDS is 3,000 ppm or less, and "-5" is added if the TDS is 5,000 ppm or less. EXAMPLE= You need a 320,000 GPD system and your feed water has a TDS of 5,000 ppm, you would order Model Number "BW-320K-7680-5".
