Large‑scale municipal water‑plants need huge daily water‑production capacity. Deploying dozens of small‑size 4‑inch UF membrane module occupies large workshop space and increases installation cost. Our Oil Filtration Machine matched LF‑U‑8040 large‑flow UF membrane is flagship industrial‑grade Ultrafiltration membrane in our product catalog. Single‑module membrane area reaches above 40㎡, which greatly reduces module quantity for large‑capacity projects. The thick high‑tensile PVDF material of this Ultrafiltration membrane module brings excellent anti‑scouring performance and stable continuous running status. It offers reliable pre‑treatment protection for LF‑BW‑FR‑series RO membrane filter. You can find more water‑treatment spare parts via Water Filter Element. For pre‑security filtration, select High Flow Filter Cartridge.
Working Principle of LF‑U‑8040 UF membrane module
Bulk raw surface water flows through outer hollow‑fiber of LF‑U‑8040 UF membrane. The large‑area fiber layer of the Ultrafiltration membrane traps suspended solids, colloids and algae particles. Purified permeate water enters the central collecting pipe and flows to downstream Reverse Osmosis membrane element. The cross‑flow backwashing design quickly washes away contaminants accumulated on the surface of Ultrafiltration membrane module. It reduces shutdown frequency and lowers working pressure for the subsequent RO membrane.
Core Performance Parameters
Membrane Material: Modified thick‑wall PVDF for UF membrane module
Nominal Filtration Precision: 0.01μm for Ultrafiltration membrane
Single Module Membrane Area: 39.7‑44㎡ for large‑size UF membrane
Max Continuous Trans‑Membrane Pressure: 0.6 MPa

Every LF‑U‑8040 Ultrafiltration membrane module will pass fiber break resistance test before delivery. It can work together with large‑size High Flow Filter Cartridge for full‑set pre‑filtration system.
Five Core Advantages for Municipal Water Treatment Plants
1 Large Single‑Module Membrane Area
Cut down total number of Ultrafiltration membrane module required for big water‑treatment projects.
2 High Strength Anti‑Break PVDF Hollow‑Fiber
This UF membrane can endure long‑term aeration and back‑wash without fiber rupture.
3 High Daily Water Output
Suitable for 24‑hour continuous running water‑production lines.
4 Good Anti‑Pollution Performance
The Ultrafiltration membrane adapts to raw river water with moderate turbidity.
5 Standard 8‑Inch Industrial Housing
Perfect fit for standard installation racks in municipal water‑plant equipment.
Typical Application Scenarios
LF‑U‑8040 UF membrane module serves as core pre‑treatment Ultrafiltration membrane for municipal water plants. Combined with industrial‑grade Reverse Osmosis membrane element, it forms a complete water purification solution.
