Disc-Tube Reverse Osmosis Membrane (DTRO) Product
Product Description
- Membrane material: polyamide composite membrane
- Housing material: FRP (fiberglass reinforced plastic)
- Membrane plate: octagonal
- Application scenarios: leachate treatment in landfills/incineration plants, industrial wastewater reuse, leachate concentrate treatment, desulfurization wastewater treatment in power plants, and high-concentration wastewater treatment in chemical/pharmaceutical 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;
- The water quality is stable, the service life is long, the high pressure resistance and the high retention rate;
- Standardized modular component series, flexible assembly, thorough cleaning, easy maintenance and management;
- Not easy to cause pollution, good anti-scaling performance, can effectively treat high turbidity fluid;
- Low Pretreatment requirements;
- It has strong high pressure tolerance, with a maximum design pressure of 120 bar, and is suitable for high pressure systems (such as leachate concentration, zero-liquid discharge (ZLD), etc.).
