In modern water treatment, Ultrafiltration (UF) is the critical barrier between "dirty" water and "process-ready" water. Whether you are protecting downstream Reverse Osmosis (RO) membranes or recycling industrial wastewater, the quality of your UF module dictates the efficiency of your entire plant.
LOONG FILTRATION manufactures high-performance Hollow Fiber UF Modules designed for resilience. By engineering fibers with superior mechanical strength and specific pore structures, we deliver membranes that resist fouling, withstand frequent backwashing, and maintain high flux rates over a long service life.
We offer two distinct membrane chemistries to match your water conditions and budget:
The Premium Choice: Known for its exceptional mechanical strength and chemical resistance.
Anti-Fouling: Our permanently hydrophilic modification resists organic fouling, making it easier to clean.
Durability: Withstands high oxidant concentrations (Chlorine) during Clean-in-Place (CIP) cycles.
Best For: Difficult wastewater, surface water with high organics, and large-scale Desalination pre-treatment.
The Economic Choice: A cost-effective solution for standard water applications.
Performance: Delivers excellent pathogen removal and turbidity reduction at a lower capital cost.
Best For: Municipal tap water, well water purification, and light industrial applications.
Understanding that every system design is unique, LOONG provides flexible flow modes:
Outside-In Filtration:Feed water flows from the outside of the fiber to the inside. This allows for higher solids loading and more effective air scouring.
Ideal for: High turbidity feed water and MBR (Membrane Bioreactor) applications.
Inside-Out Filtration:Feed water flows through the lumen of the fiber. This provides uniform hydrodynamics and precise cutoff.
Ideal for: Cleaner feed water streams requiring absolute bacteria removal.
Our modules are validated to deliver the numbers your engineers care about:
MWCO (Molecular Weight Cut-Off): 6,000 Daltons – 100,000 Daltons.
Output Quality: Turbidity < 0.1 NTU; Silt Density Index (SDI) < 3.
Removal Efficiency: 99.99% removal of bacteria, viruses, and colloids.
RO Pre-Treatment: Significantly extends the life of RO membranes by removing colloids that cause fouling.
Wastewater Reuse: Treating textile, dyeing, or plating wastewater for recycling.
Food & Beverage: Clarification of fruit juices, soy sauce, and protein concentration.
Electrophoretic Paint: Recovery of electrophoretic paint in automotive manufacturing.
LOONG UF modules are engineered with standard dimension ports (Victaulic or Threaded) to serve as direct replacements for major international brands (e.g., Dow, Hydranautics, Suez). We provide equivalent active membrane areas to ensure your system capacity remains unchanged.
