Lanran’s Bipolar Membrane Solution at Mamicuo Salt Lake
For lithium producers operating in remote, high-altitude regions, logistics and waste management are more than operational challenges—they are direct cost drivers. At the Mamicuo Salt Lake lithium and boron project, Lanran has implemented a bipolar membrane electrodialysis system that transforms sodium chloride wastewater into two high-value streams: hydrochloric acid and sodium hydroxide. These are recycled directly back into the adsorption process, creating a closed-loop system that reduces chemical procurement costs and eliminates discharge. The 110-type bipolar membrane stack at the heart of this system is engineered for efficiency and reliability in demanding environments. Its key advantages include: Higher efficiency – More acid and alkali recovery per unit of energy Lower power consumption – Reduced operating costs over the project lifecycle Compact design – Minimal footprint, faster deployment Simplified logistics – Reduced reliance on external chemical supply chains For operations in remote environments, these advantages translate directly into improved project economics and operational independence. Installation is 50% complete and on schedule. With mechanical completion targeted for April 5 and commissioning readiness by April 30, this unit will be the first to begin operation—providing a stable acid and alkali supply to support the main lithium extraction process. Lanran brings field-proven electrodialysis technology to the lithium sector. Our solutions are designed to help producers meet environmental targets while improving process efficiency and reducing input costs. Whether your focus is on resource recovery, emissions reduction, or supply chain resilience, Lanran delivers engineered solutions that perform at altitude and at scale.
