Spiral Tube Reverse Osmosis (STRO) Membrane Products
Product Description
- Membrane material: polyamide composite membrane
- Membrane type: High-pressure seawater desalination membrane
- Housing material: FRP (fiberglass reinforced plastic)
- Flow channel type: Parallel flow channel 47mil, other sizes available
- Application scenarios: leachate treatment in landfills and incineration plants, and high-difficulty wastewater treatment in steel, pharmaceutical, and chemical industries.
Product Features
- Using imported membrane sheets, combined with its own modified patent, eliminate the micro defects on the surface of the membrane, improve the anti-fouling performance and the balance of flux/desalination rate;
- High desalination rate and stable performance, the product water quality is excellent, suitable for customers with high water consumption index;
- Special fluid hydrodynamic design to reduce concentration polarization and improve the tendency of blockage and scaling;
- The open wide channel (≥3mm) design enables better cleaning effect and easier performance recovery.
