High-salinity wastewater can create high treatment costs and ongoing demand for fresh chemicals. LANRAN’s Bipolar Membrane Electrodialysis (BPED) technology offers another option. It converts sodium sulfate (Na₂SO₄) in suitable wastewater streams into sulfuric acid (H₂SO₄) and caustic soda (NaOH), which…
In 2026, China officially released the Solid Waste Comprehensive Management Action Plan (commonly referred to as the “Solid Waste Ten Measures”). As a top-level policy framework for solid waste governance during the 15th Five-Year Plan period, it sends a clear…
From 2026 onward, China’s “15th Five-Year Plan” enters full implementation, marking a shift in industrial green transition from policy orientation to execution-driven practice. Recently, an article published in Qiushi Journal by Zheng Shanjie, Secretary of the Party Leadership Group and…
A recent industrial desalination project using electrodialysis technology has demonstrated stable and efficient purification performance for phosphorylcholine-related products. The system integrates an AIO416-500S alloy membrane electrodialysis unit together with a 416-type heterogeneous membrane system, allowing flexible operation under different production…
For many aging lithium extraction plants, the biggest challenge is no longer raw material supply — it’s production bottlenecks caused by outdated membrane performance and early-stage system design limitations. A leading salt lake lithium producer in China recently faced this…
As industries face rising sulfuric acid prices, stricter wastewater discharge regulations, and growing pressure to improve resource efficiency, more manufacturers are turning to Bipolar Membrane Electrodialysis (BPED) technology for industrial brine treatment and chemical recovery. A BPED system for sodium…
We’re honored to be featured by the Membrane Industry Association of China for our Mamicuo Salt Lake Bipolar Membrane project in Tibet, China. At an altitude of 4,400 meters, LANRAN’s BPED system is helping transform post-lithium extraction NaCl wastewater into…
In EDR systems, performance is not only defined by membranes and stacks -spacers (gaskets) play a critical role in system safety, efficiency, and longevity. At LANRAN, we design and manufacture high-performance spacers tailored specifically for demanding EDR applications. 1️⃣ Engineered…
A 10,000 t/y Resource Recovery Project in Xinjiang’s Textile Industry As the first electrodialysis application in Xinjiang’s textile industry, this project demonstrates how Bipolar Membrane Electrodialysis (BPED) converts sodium sulfate solid waste into reusable sulfuric acid and caustic soda. Using…
In many existing EDR systems, membrane replacement is often treated as a routine maintenance task. But in reality, it’s also a hidden opportunity to significantly improve system performance. At LANRAN, our semi-homogeneous ion exchange membranes (AAM & CAM) are engineered…
