Converting By-products into Reusable Chemical Resources Lithium iron phosphate (LFP) batteries are widely used in electric vehicles and energy storage systems. During iron phosphate precursor production, certain manufacturing processes generate ammonium sulfate-rich by-product streams, creating challenges in waste management and…
Converting By-products into Reusable Chemicals NCM (nickel-cobalt-manganese)Ternary precursor production for lithium-ion batteries generates sodium sulfate (Na₂SO₄) as a by-product. Managing this salt stream while reducing chemical procurement costs is an important challenge for manufacturers. LANRAN’s Bipolar Membrane Electrodialysis (BPED) technology…
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…
As lithium production expands, efficient processing and resource recovery are becoming increasingly important. LANRAN’s Bipolar Membrane Electrodialysis (BPED) technology enables the conversion of lithium salts into lithium hydroxide through a membrane-based process. From lithium sulfate, lithium chloride, and lithium carbonate…
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…
In EDR systems, every component matters — from the membrane and spacer to the complete membrane stack. At LANRAN, we provide core EDR components designed for reliable industrial desalination and concentration: 🔹 AAM & CAM 𝐌𝐞𝐦𝐛𝐫𝐚𝐧𝐞𝐬Low resistance, stable ion selectivity,…
What does 17 years in membrane separation mean? For us, it means 17 years of working on real industrial challenges. From ion exchange membranes to electrodialysis technologies and industrial systems, LANRAN has continuously developed its capabilities through R&D, engineering practice,…
As lithium demand continues to grow, efficient and cost-effective lithium concentration is becoming increasingly important. At LANRAN, our 𝐄𝐥𝐞𝐜𝐭𝐫𝐨𝐝𝐢𝐚𝐥𝐲𝐬𝐢𝐬 (𝐄𝐃) 𝐭𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲 𝐜𝐚𝐧 𝐛𝐞 𝐮𝐬𝐞𝐝 𝐭𝐨 𝐩𝐫𝐞-𝐜𝐨𝐧𝐜𝐞𝐧𝐭𝐫𝐚𝐭𝐞 𝐥𝐢𝐭𝐡𝐢𝐮𝐦-𝐜𝐨𝐧𝐭𝐚𝐢𝐧𝐢𝐧𝐠 𝐛𝐫𝐢𝐧𝐞𝐬 𝐚𝐧𝐝 𝐥𝐞𝐚𝐜𝐡𝐚𝐭𝐞𝐬 through ion transport across ion-exchange membranes, producing a lithium-rich concentrate…
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…
Water is becoming one of the most critical resources in modern industry. For oil & gas, coal chemical, metallurgy, papermaking, textile dyeing, and other water-intensive industries, the challenge is no longer simply treating wastewater — it’s recovering water and putting…
