RO-Membrane Desalination
BWRO-Membrane Desalination
Outline of the System
This desalination treatment system is to obtain pure water continuously by using Brackish Water Reverse Osmosis Membrane.
- Pretreatment Process
Producing water suitable for RO membrane flow by combining the following treatments according to the property of the raw water.- Coagulating Sedimentation
Removing hard constituents in the raw water to prevent scaling on RO membrane. - Sand Filter
Removing suspended substances in the raw water to prevent physical damage to RO membrane. - Activated Carbon Filter
Removing suspended substances in the raw water to prevent physical damage to RO membrane. - Chemical Injection
Removing microbes in the raw water to prevent biological fouling on RO membrane.
- Coagulating Sedimentation
- Safety Filter
By using 1 - 5 micrometers filter, removing fine substances, which the pretreatment process failed to remove. - BWRO Unit
By rising pressure on the pretreated water to permeate through RO membrane, ion constituents are removed, producing permeate. Removed ion constituents are discharged to the concentrate side.
Features
- Capable of producing pure water with salinity concentration of 10 microsiemens/centimeter or less.
- Resistible to the loading variation of the raw water, thus capable of producing continuously and stably pure water.
- Simple process allows easy operation control.
- In normal operation, no regeneration processing is required, thus no regenerated effluent is generated.
- Because of desalination operation under low pressure, not much power is required, resulting in low running cost.
- System is compact, allowing space-saving installation.

SWRO-Membrane Desalination
Outline of the System
This desalination treatment system is to obtain continuously plain water from sea water by using Sea Water Reverse Osmosis Membrane.
- Pretreatment Process
Removing impurities from sea water through sand filtration and / or chemical injection. - Safety Filter
By using 1 - 5 micrometer filter, removing fine substances, which the pretreatment process failed to remove. - SWRO Unit
By boosting the pretreated water to permeate through RO membrane, ion constituents are removed, producing permeate. Removed ion constituents are discharged to the concentrate side.
Features
- Allowing sea water to be used as drinking water or industrial water.
- Sea water needs to be fed into the RO Unit at high pressure, however, energy saving can be actualized by way of energy recovery by using SWRO concentrate.
