Another L𝐚𝐫𝐠𝐞-𝐬𝐜𝐚𝐥𝐞 Bipolar Membrane Electrodialysis (BPED) Project Of LANRAN Successfully Commissioned
Lanran’s latest NF + BPED system has entered stable operation at a nano-scale electronic ceramic materials manufacturing facility in Chizhou, Anhui, China, supporting resource recovery from industrial wastewater and water reuse. The system delivers:✔️ Continuous production of approximately 2N hydrochloric acid (HCl) and 2N sodium hydroxide (NaOH)✔️ Reuse of the recovered acid and alkali in upstream washing processes✔️ Recycling of production wastewater back into the manufacturing process The first phase currently operates three BPED units, producing approximately 4.5 m³/h each of hydrochloric acid and sodium hydroxide. This project demonstrates how Nanofiltration (NF) and Bipolar Membrane Electrodialysis (BPED) can recover valuable chemicals from industrial wastewater while supporting water reuse in advanced materials manufacturing. Lanran continues to provide practical membrane separation solutions that help industrial manufacturers improve resource utilization and support more sustainable production.
Salt Lake Lithium Extraction: Lanran Expands a 20,000 t/y Lithium Hydroxide Project with an Additional Electrodialysis System
As global demand for battery-grade lithium hydroxide continues to rise, improving the efficiency of salt lake lithium extraction has become a key focus for the lithium industry. Advanced electrodialysis (ED) technology enables lithium producers to concentrate lithium-rich brine more efficiently while supporting stable, large-scale production. Lanran has completed the commissioning of an additional homogeneous membrane electrodialysis system for a 20,000 t/year lithium hydroxide project at the Lago Co Salt Lake in Xizang, China. The newly installed ED unit expands the plant’s lithium brine concentration capacity and is now operating steadily as part of the overall production process. Project Highlights Why Electrodialysis Is Important for Salt Lake Lithium Extraction In modern salt lake lithium extraction plants, electrodialysis plays an important role in upgrading lithium-rich brine before downstream purification and lithium conversion. Compared with conventional concentration methods, electrodialysis offers several advantages: These benefits help improve production efficiency while supporting more sustainable lithium manufacturing. Proven Membrane Technology for Industrial Lithium Production As global investment in lithium resources continues to grow, efficient membrane separation technology is becoming increasingly important for salt lake lithium extraction, lithium refining, and battery materials production. With proven electrodialysis, bipolar membrane electrodialysis, and industrial membrane technologies, Lanran has accumulated extensive experience in the delivery of large-scale lithium projects, providing reliable and mature solutions for lithium brine concentration, resource recovery, and high-purity lithium chemical production.

Lanran’s BPED System Achieves Stable Operation at High-Altitude Lithium Salt Lake Project in Xizang
In May 2026, Lanran’s Bipolar Membrane Electrodialysis (BPED) resource recovery system successfully commenced operation at the Mami Co Salt Lake lithium project in Ngari, Xizang, at an altitude of 4,480 meters. Following system commissioning and process optimization, the plant has entered a stable continuous operation phase. Integrated with a 50,000 t/y lithium carbonate production base, the project utilizes Lanran’s BPED technology to convert sodium chloride-rich by-product streams generated during lithium extraction into reusable hydrochloric acid (HCl) and sodium hydroxide (NaOH). This closed-loop process reduces waste generation, lowers chemical procurement costs, and supports more sustainable lithium production. Despite the challenges of high-altitude construction and operation, the project team successfully completed equipment installation, system integration, commissioning, and performance verification. On June 2, the BPED system achieved stable acid and alkali production, with product quality exceeding design requirements. Supported by a centralized DCS control system, the plant continuously optimizes operating parameters to ensure stable product quality and long-term operational reliability under demanding plateau conditions. As another successful application of Lanran’s proven salt lake lithium extraction solutions, the Mami Co project highlights the maturity and industrial readiness of Bipolar Membrane Electrodialysis technology. The system enables on-site conversion of waste salt streams into valuable acids and alkalis for internal reuse, helping lithium producers improve resource utilization, reduce chemical consumption, and advance low-carbon, circular production practices. As a specialist in membrane separation and resource recovery technologies, Lanran remains committed to advancing sustainable solutions for lithium extraction, battery recycling, industrial wastewater treatment, and acid/alkali recovery applications worldwide.
