Reverse Osmosis (RO) and Ultrafiltration (UF) are both membrane filtration technologies used to purify water. UF removes larger particles, bacteria, and organic molecules, often used as a pre-treatment for RO, which filters out dissolved salts, ions, and smaller contaminants. Combined, they provide a multi-stage filtration solution for high-purity water treatment.
RO–UF Solutions Tailored for Every Water Challenge.
Engineered for wastewater, process water, seawater, and brackish water treatment.
| Feature | RO Systems | UF Systems |
|---|---|---|
| Filtration Pore Size | Very fine, removes ions and dissolved salts | Larger pore size, removes suspended solids, bacteria, and larger molecules |
| Energy Requirement | Higher (requires pressure to force water through membrane) | Lower energy consumption |
| Applications | Desalination, drinking water, high-purity water production | Pre-treatment for RO, wastewater treatment, water filtration |
| Membrane Cleaning | Frequent cleaning due to fouling from dissolved salts | Less frequent cleaning and lower fouling risk |
