Introduction
LEFILTER, a leading Chinese manufacturer specializing in fluid environmental protection solutions, introduces the Ultrafiltration Equipment Model LFUF-12. Engineered for high-efficiency water treatment, this system is designed to meet the rigorous demands of sewage treatment plants, industrial processes, and potable water production. With a focus on durability, energy efficiency, and ease of operation, the LFUF-12 delivers superior performance while reducing operational costs.
Product Structure
The Ultrafiltration Equipment Model LFUF-12 features a modular design with integrated components for optimal water treatment:
- Membrane Housing:
- Constructed with FRP (Fiberglass Reinforced Plastic) for corrosion resistance.
- Accommodates multiple Ultrafiltration membrane modules.
- Inlet Pump:
- Grundfos or Southern Pump (CNP) for reliable water supply.
- High-Pressure Pump:
- Ensures sufficient pressure for membrane filtration.
- Control System:
- PLC-based automation for real-time monitoring and adjustment.
- Filtration Media:
- PVDF (Polyvinylidene Fluoride) hollow fiber membranes with precise pore sizes (0.01–0.1 μm).
- Frame:
- Stainless steel square tube with polished surface for structural integrity.
Application in Sewage Treatment Plants
The Ultrafiltration Equipment Model LFUF-12 is ideally suited for sewage treatment plants, addressing critical challenges:
- Contaminant Removal:
- Efficiently removes suspended solids, colloids, bacteria, and viruses.
- Achieves turbidity reduction of ≥99.9%, ensuring clarified water for reuse or discharge.
- Water Reuse:
- Purifies sewage for non-potable applications (e.g., irrigation, industrial cooling).
- Reduces freshwater consumption and environmental impact.
- Efficiency:
- Handles flow rates up to 12 m³/h with low energy consumption.
- Low chemical usage minimizes operational costs.

Working Principle
The LFUF-12 operates through a three-stage process:
- Pre-Filtration:
- Coarse particles are removed by a pre-filter.
- Ultrafiltration:
- High-pressure pump forces water through PVDF hollow fiber membranes.
- Membranes with pore sizes of 0.01–0.1 μm trap suspended solids, colloids, and microorganisms.
- Post-Treatment:
- Treated water is disinfected (optional) and stored for reuse.

Key Features & Advantages
- High Filtration Efficiency:
- Removes ≥99.9% of turbidity and pathogens.
- Maintains consistent performance even with varying feed water quality.
- Energy Efficiency:
- Low-pressure operation reduces energy consumption by up to 30%.
- Durable Construction:
- FRP housing and stainless steel components resist corrosion.
- Automation:
- PLC control system monitors and adjusts operations in real time.
- Low Maintenance:
- Self-cleaning backflush function minimizes downtime.
- Modular design simplifies membrane replacement.
