All spare parts undergo strict quality inspections, guaranteeing performance equivalent to original components. Furthermore, our long-term technical support services allow customers to consult our experts at any time for guidance and troubleshooting, ensuring smooth system operation. Customer Success Story: Rapid Response and Problem Resolution In August 2022, a BPED customer in Anhui, China, reported an issue with elevated sulfate levels in the alkali chamber, which directly affected product quality. Lanran Tech’s after-sales team took immediate action: ✅ Swift Diagnosis: Within 48 hours, our technical team arrived on-site, conducted membrane stack analysis and water quality tests, and identified excess multivalent metal ions causing cation membrane damage as the root cause. ✅ Efficient Repair: We urgently deployed new membrane stacks, optimized the ion exchange regeneration process (switching to hydrochloric acid regeneration), and implemented a hardness monitoring system, ensuring inlet water hardness remained ≤0.5 mg/L. ✅ System Optimization: By adjusting operational parameters, controlling lithium concentration, and regulating alkali replenishment, sulfate levels were successfully reduced to ≤0.4 g/L. The system’s output was restored to 3.5 m³/h (design capacity), ensuring compliance with product quality standards. Commitment to Excellence At Lanran Tech, exceptional after-sales service is more than just technical support. Together, we are driving the application of Bipolar Membrane Electrodialysis (BPED) technology in the resource recovery of wastewater from battery dismantling and recycling, as well as the battery production process, promoting a circular economy in the lithium battery industry and fostering sustainable development. We will continue to strive to provide customers with higher-quality products and services. Lanran Technology will always adhere to a customer-centric approach, continuously innovating and delivering excellent services, ensuring stable, clean, and sustainable production, and supporting the development of a circular economy for our clients.
