23% More Processing Capacity, Over 99% Lithium Recovery
Another milestone for LANRAN in salt lake lithium extraction! LANRAN has successfully completed the commissioning of three additional AC110-1000 homogeneous membrane electrodialysis units for the Phase I expansion of the Lagoco Lithium Project in Xizang, China. The project is designed to produce 20,000 tonnes of battery-grade lithium hydroxide monohydrate annually. The three newly added units bring measurable improvements to the existing lithium processing system: 📈 23% Increase in Processing CapacityAverage daily treatment of 4N permeate increased from approximately 2,270 m³ to 2,800 m³, adding around 22 m³/h of processing capacity. ♻️ Lithium Recovery Exceeds 99%The system’s lithium recovery rate increased from approximately 95–96% to over 99%, with lithium concentration in the discharged dilute stream below 100 mg/L. ⚙️ Smarter Operation and MonitoringNew automatic hydraulic stations enable one-button startup and automatic pressure maintenance. Online voltage monitoring allows operators to track the voltage distribution of individual membrane stacks in real time, supporting more stable system operation. More processing capacity. Higher lithium recovery. More stable operation. Through continuous innovation in ion exchange membranes and electrodialysis technology, LANRAN is helping lithium producers improve resource utilization and optimize production processes.
Making L-Carnitine Production Cleaner with Electrodialysis Technology
Efficient desalination is an important step in L-Carnitine production. How can manufacturers reduce salt content while minimizing chemical consumption and wastewater generation? LANRAN’s Electrodialysis (ED) technology provides an effective approach. In an L-Carnitine production process in Taizhou, Jiangsu, China, the intermediate solution undergoes hydrolysis and pH adjustment before entering the ED system. Using ion exchange membranes, electrodialysis separates sodium and chloride ions from the target solution. The process is straightforward: the desalinated stream proceeds to three-effect evaporation and subsequent refining, while the concentrated stream enters MVR evaporation crystallization for volume reduction and salt separation. What makes this process valuable? By integrating electrodialysis with evaporation and crystallization, LANRAN helps optimize material treatment and supports cleaner, more resource-efficient production. Project Data: Treatment capacity: 2.3 m³/h Conductivity: ≤100 μS/cm Energy consumption: 76 kWh/t Overall current efficiency: 62.8% LANRAN – Separation Redefined, Solutions Refined.
