Lanran Tech Powers the World’s Largest MLD Project Recognized at the 2025 Global Water Awards
The 2025 Global Water Awards, widely regarded as the “Oscars” of the water industry, have officially announced this year’s winners. The Foshan Jialida Textile Wastewater ZLD Project was awarded Industrial Water Project of the Year for its outstanding achievements in near-zero liquid discharge and resource recovery in textile wastewater treatment.
The project utilizes a combination of near-zero discharge (NZLD) system, achieving an impressive 88.7% water reuse rate. Out of a total daily treatment capacity of 160,000 m³, approximately 142,000 m³/day is reused within the industrial park. Furthermore, the system recovers 1,000 m³/day of sodium chloride brine (with concentrations up to 200 g/L), contributing to both environmental sustainability and economic growth.
As a key technology provider, Hangzhou Lanran Tech supplied the electrodialysis (ED) concentration system and bipolar membrane electrodialysis (BMED) acid-base production system, contributing significantly to the project’s recognition on the international stage.
Electrodialysis Concentration System:
Lanran’s homogeneous-membrane electrodialysis system plays a central role in concentrating sodium chloride wastewater.
Designed with high automation and operational flexibility, the system operates using a two-stage freshwater tank overflow setup, capable of fully automated control. Voltage and current are adjusted in real time based on feedwater salinity. Modular configuration enables independent operation of each unit, allowing seamless transitions between operational modes based on actual conditions. This enables high-efficiency system management and ensures reliable performance across varying loads.
Bipolar Membrane Acid and Alkali Production System:
The project also integrates BMED units from Lanran Tech. The acid and alkali produced are partly used for resin regeneration and partly supplied back to enterprises within the industrial park, further enhancing the resource loop of the ZLD system.
About the Project
The Foshan Jialida project marks a significant milestone in the textile industry’s shift toward circular wastewater treatment. It is the first known case to implement selective salt separation and purification in textile wastewater reuse on this scale.
