Precipitated silica, also known as white carbon black, is widely used in rubber, plastics, coatings, and toothpaste. Manufacturers typically produce it by reacting sodium silicate with an acid. The process generates wastewater containing residual silica and sodium sulfate, especially during…
In kraft pulp and paper production, chloride and potassium can accumulate in the chemical recovery cycle, increasing the risk of corrosion and scaling and affecting stable operation. For Dingfeng Paper, LANRAN applied Bipolar Membrane Electrodialysis (BPED) to remove part of…
Steel production generates high-salinity wastewater that can be difficult to treat. As water reuse and zero liquid discharge (ZLD) become more important, managing reverse osmosis (RO) concentrate remains a key challenge. Final evaporation can consume significant energy. Therefore, reducing the…
Bipolar Membrane Electrodialysis (BPED) offers a practical way to convert dissolved salts into acids and alkalis. It uses water dissociation to generate H⁺ and OH⁻ ions, supporting chemical conversion through membrane separation. LANRAN’s BPED Solution for Molybdate Conversion In this…
Recycling spent lithium iron phosphate (LFP) batteries helps recover valuable lithium and supports more sustainable battery supply chains. Efficient lithium recovery also plays an important role in improving resource utilization. Located in Qujing, Yunnan Province, China, this battery recycling expansion…
Lanran is advancing an electrodialysis expansion project for lithium recovery at Chalco Henan Branch, supporting more efficient lithium resource recovery from alumina production. Industrial Electrodialysis for Lithium Recovery The project is an industrial demonstration project focused on recovering lithium associated…
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…
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,…
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…
High-salinity wastewater can create high treatment costs and ongoing demand for fresh chemicals. LANRAN’s Bipolar Membrane Electrodialysis (BPED) technology offers another option. It converts sodium sulfate (Na₂SO₄) in suitable wastewater streams into sulfuric acid (H₂SO₄) and caustic soda (NaOH), which…
