Membrane Performance
The FR-8040 membrane is developed for medium and large-scale RO systems requiring both fouling resistance and high production capacity. Under standard test conditions, it delivers 10,500 GPD (40 m³/d) permeate flow while maintaining a stabilized salt rejection of 99.6%.
Its fouling-resistant membrane structure helps support stable operation in applications where feed water quality may increase the risk of membrane contamination.
Applications
- Wastewater recycling projects
- Commercial reverse osmosis systems
- Food and beverage water treatment
- Process water production
- Pretreated surface water desalination systems
FAQ
Q1.What is the salt rejection rate of the FR-8040 membrane? What after‑sales services do you provide beyond standard support?
A:We offer a "full‑lifecycle response" service package.
Q2.What special packaging and shipping guarantees do you offer?
A:We use double moisture‑proof sealing + inert gas protection to keep the membrane elements wet during long-distance sea or land transport.
Q3.What feed water sources can this membrane handle?
A:The membrane is commonly used with municipal water, surface water, reclaimed water, pretreated wastewater, and industrial process water with moderate fouling potential.
Q4.How often should the membrane be cleaned?
A:Cleaning frequency depends on feed water quality and operating conditions. Monitoring permeate flow, differential pressure, and salt rejection can help determine the appropriate cleaning schedule.
