Specialized Reverse Osmosis Membranes for Reclaimed Water Applications
Product Description
- Membrane characteristics: high pressure resistance
- Membrane material: polyamide composite membrane
- Outer wrapping type: fiberglass
- Feed spacer type: flat flow channel 31mil/34mil/46mil, etc.
- Application scenarios: industrial wastewater reuse, municipal reclaimed water reuse, high salt wastewater concentration, etc.
Product Features
- The imported membrane sheet is combined with the own modified patent to eliminate the micro defects on the surface of the membrane, improve the anti-fouling performance, and balance the flux and retention rate performance is better;
- Parallel open flow channel design, no dead zones cleaning, less scaling, excellent recovery performance;
- With strong acid and alkali resistance, its chemical stability is significantly improved compared with traditional RO membranes;
- It has low pretreatment requirements, allows higher COD and SS inflow, and has excellent anti-pollution performance.
