The LJ1 type submerged PM composite membrane curtain is a high-performance membrane module manufactured using newly developed acid and alkali-resistant ultrafiltration membrane material. Leveraging its extreme chemical tolerance and stable filtration performance, this product is specifically designed to handle industrial wastewater with complex compositions and severe pH fluctuations. It serves as a reliable core component in MBR (Membrane Bioreactor) and MCR (Membrane Chemical Reactor) processes for treating challenging wastewater.
Exceptional Chemical Resistance: Utilizes a new formulation that can withstand strong acid and alkali chemical cleaning within a pH range of 1-14. It maintains excellent membrane performance and structural integrity even in harsh chemical environments, significantly expanding its application boundaries.
Efficient Hydrophilic Filtration: The filter layer possesses good hydrophilicity and an asymmetric structure, ensuring stable operation under high flux. With a membrane retention pore size of 0.04 microns, it effectively intercepts suspended solids, colloids, bacteria, and macromolecular organic matter.
Broad Process Applicability: Optimized for advanced membrane-based water treatment processes like MBR and MCR, it is particularly suitable for industrial wastewater treatment scenarios with large water quality fluctuations requiring frequent or intensive chemical cleaning.
Robust and Reliable Structure: Features good mechanical strength, ensuring long-term stable operation under complex working conditions with easy maintenance.
With its unparalleled acid and alkali resistance, this product is particularly suitable for the following demanding fields requiring extremely high chemical stability from membrane materials:
Chemical and Pharmaceutical Wastewater: Treats process wastewater containing strong acids, alkalis, organic solvents, or high salt content, tolerating extreme pH shocks and potent chemical cleaning.
Electroplating and Metal Processing Wastewater: Suitable for wastewater treatment systems containing heavy metals, acid/alkali detergents, and complexing agents. The membrane module maintains stable performance under frequent acid/alkali washing.
Landfill Leachate Treatment: Handles leachate with extremely complex composition, high pollutant concentration, and severe water quality fluctuations. Its chemical resistance ensures the system’s long-term continuous operation.
Industrial Wastewater Standards Upgrade and Zero Liquid Discharge (ZLD) Pretreatment: Serves as a corrosion-resistant membrane unit for the advanced treatment and reuse of challenging wastewater, providing stable and reliable feed water for subsequent processes like Reverse Osmosis (RO).
The LJ1-PM membrane curtain is an ideal choice for treating highly corrosive and highly polluted industrial wastewater. It effectively reduces system maintenance risks, extends membrane service life, and provides solid assurance for customers to achieve stable compliance, resource recovery, and cost control.
