Forward Osmosis Process
- The feed is concentrated
- Dilution of the draw solution
- Draw solution needs to be recovered
- Permeate is produced
Examples of draw solution recovery technologies
- Reverse Osmosis: BWRO (0 – 30 g TDS/L)
- Reverse Osmosis: SWRO (30 – 70 g TDS/L)
- High Brine Reverse Osmosis: HBRO (70 – 140 g TDS/L)
- Membrane Distillation: MD (140 – 250 g TDS/L)
