The LGJ2C-2000X140 submerged ultrafiltration membrane module is the flagship integrated membrane stack within the LGJ2 series, designed for ultra-large-scale water treatment projects. Through highly integrated engineering design, it concentrates 140 high-performance PVDF membrane elements into one compact module, achieving maximum membrane area per unit footprint. It inherits the revolutionary low-energy aeration technology of the LGJ2 series and is reinforced for the stable, efficient operation of large municipal and industrial wastewater treatment plants. It is the cornerstone for building modern, intensive membrane-based water treatment cores.
Ultra-Large-Scale Integration, Extreme Space Savings: A single module integrates 140membrane elements, providing extremely high membrane packing density. This significantly reduces the footprint of membrane tanks and civil construction costs, making it particularly suitable for space-constrained sites or large-scale expansion projects.
Inheritance of Efficient Energy-Saving Technology: Upholds the optimized aeration system of the LGJ2 series, maintaining effective membrane scouring while operating at a low air-to-water ratio, delivering significant operational energy savings for super-large projects.
Excellent and Stable Product Water Quality: Employs PVDF membranes with a 0.02-micron pore size, producing excellent water quality (SDI₁₅ < 3, turbidity < 0.1 NTU), suitable as high-quality pretreatment for Reverse Osmosis (RO) or for direct production of high-standard reuse water.
Robust and Reliable Industrial-Grade Design: The main frame is constructed from SUS304 stainless steel, and the product water header uses UPVC, ensuring corrosion resistance and structural strength for long-term immersion and chemical cleaning environments, guaranteeing long-term reliable operation.
The LGJ2C large-scale submerged membrane module is core equipment supporting strategic water treatment infrastructure, suitable for:
Large / Ultra-Large Municipal Wastewater Treatment Plant Upgrading & Expansion: Serves as the core membrane treatment unit in new or retrofit projects, directly treating large volumes of wastewater, steadily elevating effluent quality to Surface Water Class IV standards or higher, or meeting high-quality reclaimed water production requirements.
Regional Water Reclamation Plants and Water Resource Hubs: Acts as the core filtration module in basin-scale water resource recovery facilities, providing cities with stable ecological补水, industrial cooling water, or municipal non-potable water sources.
Industrial Park Comprehensive Wastewater Treatment Centers: Centrally treats complex industrial wastewater exceeding tens of thousands of tons per day. Its modular, large-scale characteristics facilitate unified management, operation, and maintenance, achieving economies of scale.
Benchmark Projects for Large-Scale Membrane Water Treatment Technology Application: Suitable for large benchmark projects with extremely high requirements for technological reliability, operational economy, and land use efficiency.
The LGJ2C-2000X140 membrane module not only represents powerful single-unit processing capacity but also reflects advanced levels in system integration and engineering optimization. It delivers a high-performance, “plug-and-play” membrane treatment core to customers, significantly reducing design complexity and implementation risks for large-scale projects.
