Both brackish water RO and seawater RO remove salts using reverse osmosis technology, but because the salinity and osmotic pressure of the feed water differ,
they require different operating pressures and membrane specifications.
The lower the salinity, the lower the pressure needed to overcome osmotic pressure,
so brackish water RO operates at low pressure under low-TDS conditions.
Seawater RO, on the other hand, must overcome high osmotic pressure and therefore requires membranes suited to high-pressure operation with high salt rejection.
Because brackish water RO can operate at relatively low pressure, it helps reduce the burden of high-pressure equipment and energy, and where energy savings are particularly important, the LE (Low Energy) or ULE (Ultra Low Energy) series can be applied.

• Brackish water RO: Feed TDS 1,000–12,000 mg/L, operating pressure approx. 100–220 psi (7–15 bar)
• Seawater desalination RO: Feed TDS 5,000–50,000 mg/L, operating pressure 800–1,000 psi (55–70 bar)

Yes. However, RO alone does not reach the water quality required by semiconductor or display processes, so a configuration combining EDI or ion exchange resins downstream is required.
A typical process configuration is: raw water (brackish) → pre-treatment → brackish water RO → EDI or ion exchange resin → pure/ultrapure water → point of use.
Samyang supplies RO membranes, EDI, and ion exchange resins (IER) in-house, enabling it to offer integrated solutions covering the entire process from raw water conditions to final required water quality.
