RO-Membrane Desalination

BWRO Membrane Desalination System

System overview

This is a desalination treatment system that uses a Brackish Water Reverse Osmosis Membrane to continuously deliver purified water.

  1. Pretreatment process
    Depending on the properties of the raw water, the following treatments are combined to make the water suitable for passing through the RO membrane.
    • Flocculation-sedimentation system
      To prevent scaling on the RO membrane surface, it removes the hardness components from the raw water.
    • Sand filtration treatment
      To prevent physical damage to the RO membrane, it removes the suspended substances from the raw water.
    • Activated carbon treatment
      To prevent chlorine degradation of the RO membrane, it removes the residual chlorine from the raw water.
    • Chemical injection
      To reduce biofouling and scaling on the RO membrane, it injects chemicals.
  2. Security filter
    Fine substances that could not be removed in the pretreatment process are removed with a filter of 1 to 5 μm.
  3. BWRO unit
    Pretreated water is pressurized and passed through the RO membrane to obtain the permeate, from which ionic components have been removed.
    The removed ionic components are discharged to the concentrated water side.

Features

  1. It delivers purified water with 10 μS/cm or lower.
  2. It is resistant to the load fluctuation in raw water, and can deliver purified water continuously with stability.
  3. The simplicity of the process makes operation management easy.
  4. Since chemical regeneration is not required during normal operation, regeneration waste liquid is not generated (however, periodic chemical cleaning is necessary).
  5. It’s low-pressure desalination operation results in low power consumption and reduces running costs.
  6. The equipment is compact in size and can be installed in a space-saving manner.
