The LJ1 type submerged PVDF composite membrane curtain is a high-performance membrane module specifically designed for advanced water treatment processes. Manufactured from high-strength PVDF (Polyvinylidene Fluoride) material and combined with a unique composite and asymmetric structure, it demonstrates exceptional filtration performance and operational reliability in treating industrial wastewater and various complex water qualities. It is particularly suitable for advanced process systems such as MBR (Membrane Bioreactor) and MCR (Membrane Chemical Reactor).
Excellent Mechanical Strength: Robust membrane fibers with strong tensile and peel resistance ensure long-term operation without filament breakage, extending service life.
Efficient Filtration Performance: The filter layer features good hydrophilicity. The asymmetric structure balances high filtration precision and flux, with a stable retention pore size of 0.02 microns, effectively removing suspended solids, bacteria, and most viruses.
Outstanding Chemical Tolerance: Resists routine chemical cleaning (e.g., sodium hypochlorite, acid solutions), making maintenance easy, restoring membrane flux, and reducing long-term operating costs.
Broad Applicability: Specifically optimized for industrial wastewater treatment needs, it is an ideal core component for membrane-based water treatment processes like MBR and MCR.
This product is particularly suitable for the industrial wastewater treatment sector, where stringent effluent quality, high sludge concentration, and significant water quality fluctuations are common. It is a reliable choice for achieving stable compliance and reuse in the following scenarios:
Industrial Park Comprehensive Wastewater Treatment: Used in MBR systems to efficiently intercept activated sludge and macromolecular organic matter, achieving highly efficient solid-liquid separation. The effluent can be directly reused for landscaping, flushing, or further advanced treatment.
High-Concentration Organic Wastewater Treatment: Suitable for wastewater from industries like food processing, brewing, and pharmaceuticals. Its excellent anti-fouling and chemical cleaning resistance handles the membrane fouling challenges posed by high organic loads.
Wastewater Standards Upgrade and Reclaimed Water Reuse: By adding or upgrading to MCR/MBR processes in existing wastewater treatment facilities, it utilizes its fine 0.02μm retention capability to effectively remove suspended solids, colloids, and microorganisms, ensuring effluent meets higher discharge or reuse standards (e.g., Class 1A or reclaimed water quality requirements).
With its reliable performance, flexible product models, and easy-to-integrate design, the LJ1 membrane curtain provides customers with a stable and efficient membrane filtration solution, helping to achieve water quality improvement and resource recovery.
