The high-flow filter cartridge installed before RO membrane is the last critical physical protection barrier of the reverse osmosis system. Conventional small filter cartridges require a large number of parallel installation, occupying space and increasing labor replacement costs. Our pleated large-flow security filter cartridge has high dirt holding capacity and low pressure drop, which can replace dozens of standard small filters, efficiently intercept pipeline rust, broken UF membrane fiber fragments and filter material debris to prevent irreversible scratches on TFC RO membrane separation layer.
All RO front-end protective filter cartridges and matched RO membrane & UF membrane modules are covered in our complete water filter element series.
Application Fields
1. All types of industrial RO membrane systems brackish water / seawater desalination equipment
2. Large power plant, chemical factory ultrapure water security filtration
3. Oilfield wastewater pretreatment supporting reverse osmosis equipment
4. Food beverage factory pure water production line pre-RO filtration
5. Municipal wastewater reuse dual-membrane system terminal security filtration
6. Large commercial centralized water purification equipment front-end protection
Core Selling Points
1. Large dirt holding capacity: Extend filter cartridge replacement cycle, reduce shutdown maintenance times
2. Low pressure drop design: Avoid increasing system operating energy consumption
3. Gradient multi-layer pore structure: Intercept particles step by step, not easy to block quickly
4. Food-grade EPDM sealing gasket: Zero fluid bypass, ensure full filtration of inlet water
5. Standard universal size: Compatible with mainstream large-flow filter housings on the market
6. Multiple material options: PP, glass fiber, PTFE to match different raw water quality requirements
The standard matching rule for RO security filtration: 5μm precision high-flow filter cartridge must be configured after UF membrane to form two-stage solid-liquid separation protection for RO elements.
