The LGJ1 type ultrafiltration membrane module is a high-performance submerged membrane stack designed for large-scale, continuously stable water treatment projects. Through highly integrated modular design, it encapsulates a vast number of PVDF membrane fibers within a robust frame, forming a powerful independent filtration unit. With its exceptional product water quality, outstanding chemical tolerance, and significant treatment capacity, the LGJ1 membrane module has become a core equipment choice for large municipal wastewater treatment, industrial wastewater reuse, and regional water resource regeneration.
Powerful Large-Scale Processing Capacity: Single-module membrane area reaches up to 1612 m² to 1980 m², providing extremely high processing efficiency per unit space. Particularly suitable for large-scale projects exceeding 10,000 tons/day, it can significantly reduce membrane tank footprint and system complexity.
Excellent Industrial-Grade Reliability: The core utilizes PVDF membrane with a 0.02-micron pore size, offering superior mechanical strength and fouling resistance. The design allows operation within a broad pH 1-13 range, tolerating routine chemical cleaning, ensuring long-term stable performance under complex water quality conditions.
Optimized Engineering Design: The structure is robust with standardized interfaces (product water outlet / aeration inlet), facilitating quick installation, connection, and maintenance. Hydraulic distribution is optimized for large-scale applications, ensuring uniform flux across all membrane elements within the module.
Superior Product Water Quality: Produces low-turbidity water that can directly meet high-standard reuse requirements or serve as high-quality pretreatment for advanced treatment processes like Reverse Osmosis (RO).
The LGJ1 large-scale submerged membrane module is a core component for building modern, intensive wastewater treatment plants, particularly suitable for:
Upgrading/Retrofitting and New Construction of Large Municipal Wastewater Treatment Plants: Serves as the core membrane stack in MBR processes, steadily elevating effluent quality to Surface Water Class IV standards or higher. It is key equipment for achieving wastewater resource recovery and reuse.
Industrial Park Comprehensive Wastewater Treatment and Reuse Centers: Centrally treats large volumes of complex industrial wastewater. Its powerful single-module treatment capacity facilitates system integration and operation management, achieving stable compliance and water conservation/emission reduction.
Regional Water Reclamation Plants: Provides cities with stable water for landscape/environmental补水, industrial cooling, or municipal non-potable uses. It is vital infrastructure for ensuring sustainable water resource recycling.
Landfill Leachate Treatment and Other High-Difficulty Wastewater Treatment: With its broad pH tolerance, it can be applied in systems treating special wastewater with complex compositions and high pollution loads.
The LGJ1 ultrafiltration membrane module, with its engineering-proven reliability, powerful treatment scale, and flexible adaptability, provides customers with an efficient, stable, and easy-to-manage core solution for implementing large-scale water treatment projects.
