Veolia AG8040F-400 - High Salinity Rejection High-Flow - Industrial Water Treatment Anti-Fouling Long-Life - RO Membrane Element

The Veolia AG8040F-400 is a high-efficiency reverse osmosis membrane element designed for industrial and municipal water treatment systems requiring reliable desalination, ultrapure water production, and wastewater reuse. Built with advanced thin-film composite (TFC) polyamide technology, this spiral-wound membrane offers exceptional salt rejection and durability under high-pressure conditions.

Its 8-inch diameter and 40-inch length (standard 8040 configuration) ensure compatibility with industrial RO skids, making it a cornerstone of large-scale water purification systems. The AG8040F-400 is engineered to handle challenging feedwaters, including seawater, brackish water, and industrial effluents, while resisting fouling, scaling, and chemical degradation.

The membrane's robust construction features a fiberglass-reinforced outer shell and anti-telescoping end caps, which prevent physical damage during pressure surges. Veolia's proprietary surface modification technology enhances hydrophilicity, reducing organic fouling and extending operational lifespan. Ideal for industries such as power generation, pharmaceuticals, and food processing, this membrane delivers consistent performance with minimal maintenance.

The AG8040F-400 is indispensable in sectors demanding high-purity water or sustainable wastewater management:

• In desalination plants, it converts seawater or brackish water into potable or process water
• Power plants utilize it to produce ultra-pure boiler feedwater
• Semiconductor manufacturers rely on the membrane for deionized water production
• Municipal wastewater treatment facilities deploy it for water reuse
• Food and beverage producers use it to remove contaminants from ingredient water
• Supports zero liquid discharge (ZLD) systems by concentrating brine for evaporation
