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…
Turn Sodium Sulfate into Valuable Resources In many industries, sodium sulfate (Na₂SO₄) is generated as a byproduct—often leading to high disposal costs and environmental compliance pressure. Lanran’s Bipolar Membrane Electrodialysis (BPED) technology offers a practical solution:✔ Convert sodium sulfate into…
In continuous industrial processes such as refining, natural gas treatment, and acid gas removal, organic amines are widely used to absorb carbon dioxide and other acidic gases. Maintaining amine solution performance requires effective management of byproducts, particularly Heat Stable Salts…
For many industrial water systems, scaling and fouling remain persistent challenges—especially when treating high-hardness or complex feedwater. Conventional membrane processes often require intensive pretreatment and frequent cleaning. Electrodialysis Reversal (EDR) offers a different approach. By periodically reversing electrode polarity, EDR…
Hangzhou Lanran Technology Co., Ltd. will participate in IE expo China 2026, taking place from April 13–15, 2026, at the Shanghai New International Expo Centre (SNIEC). You are welcome to visit us at Booth N1-126. As one of Asia’s leading…
As the EU accelerates its climate agenda under the Carbon Border Adjustment Mechanism (CBAM), carbon emissions are no longer just an environmental concern—they are becoming a direct cost factor in international trade. What is CBAM—and why it matters CBAM is…
