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.
A Little Surprise for Our Lanran Ladies
This Women’s Day, we wanted to do something more than just greetings. So we put together a small surprise for all our female colleagues:💐Fresh flowers to brighten the day，🍰 Sweet treats because why not，💰 And a little cash gift—because appreciation feels even better when it’s real. Simple gestures, but our way of saying: we see you, we value you, and we’re grateful to have you on the team. Happy Women’s Day to all the amazing women out there!💛
From Tibet to Qinghai: Why China’s Top Salt Lake Lithium Projects Choose the Same Core Technology?
Ever wonder what powers the lithium behind the energy transition? Look to China’s salt lakes. 🏔️ And there, you’ll find a consistent pattern: the leading projects, from mega-expansions to high-altitude pioneers, integrate electrodialysis (ED) and bipolar membrane electrodialysis (BMED). At Lanran, we’re proud to be the technology partner behind this trend. Our map tells the story: Our ED/BMED systems are on the ground across major lithium regions. Success here isn’t about one-off sales; it’s about repeat partnerships. When a client’s Phase 1 works, they come back for Phase 2 and Phase 3. Here’s what we repeatedly deliver:✅ Scalable Concentration & Purification: Reliable, high-capacity ED for lithium enrichment and critical boron removal.✅ The On-Site Chemical Plant: Game-changing BMED technology that generates acid and alkali on-site from salts. This solves huge logistical headaches in remote areas and enables direct production of battery-grade lithium hydroxide.✅ The Process Integration Expertise: We don’t just ship stacks. We co-design solutions that fit seamlessly into “adsorption + membrane” flow sheets, de-risking project execution. Two quick examples: For a Qinghai Mega-Project: Our ED system became the core of their multi-phase, 10k+t/y expansion for its unwavering reliability. For a Tibetan Pioneer: Our ED+BMED combo enabled a groundbreaking process at 4,500m+, eliminating acid transport and fast-tracking battery-grade LiOH production. The lesson is clear: for efficient, sustainable, and operationally smart salt lake lithium extraction, advanced membrane technology is non-negotiable. We are Lanran. We make the core membrane systems that make lithium extraction work. 👉 Explore the full LANRAN Salt Lake Lithium project map to see all our references: https://www.google.com/maps/d/edit?mid=1dYANYXUo38jvvjJpdj81n2wktdSPtpM&usp=sharing
