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…
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…
What if sodium sulfate could become a resource instead of a waste stream? Many industrial processes generate sodium sulfate-containing streams that require further handling, whether through disposal, landfill, or low-value sales. Bipolar Membrane Electrodialysis (BPED) offers a different approach by…
In fermentation, biochemical, and pharmaceutical processes, organic acids are often recovered or neutralized as sodium salts. Converting these salts back into free organic acids traditionally requires external acids, which can introduce additional salts and increase downstream treatment requirements. Bipolar Membrane…
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…
Why Does the Cement Industry Need Carbon Capture? The cement industry is one of the world’s largest industrial sources of carbon dioxide (CO₂) emissions. While improving energy efficiency, increasing the use of alternative fuels, and reducing clinker content can help…
