Acid & Alkali Concentration: Recover More, Waste Less

Many industries generate acidic and alkaline wastewater during production. Common sources include steelmaking, chemical manufacturing, dyeing, electroplating, mining, textiles, papermaking, and petroleum refining. These wastewater streams often have different acid and alkali levels. In addition, they may contain dissolved salts,…

High-Salt Textile Wastewater: A Waste or a Resource?

For textile dyeing and finishing plants, high-salt wastewater brings three major challenges: ❌ Higher chemical costs — Plants need fresh acid and alkali for production. Meanwhile, valuable salts in wastewater go unused. ❌ Waste treatment pressure — High salt levels…

From Lithium Salts to Battery-Grade Lithium Hydroxide

As demand for lithium-ion batteries grows, efficient lithium processing is becoming increasingly important. LANRAN’s Bipolar Membrane Electrodialysis (BPED) technology converts lithium salts into lithium hydroxide monohydrate (LiOH·H₂O), with valuable acids recovered as by-products. ♻️ One-step conversion. High product purity. Lower…

Ammonium Sulfate Recovery from LFP Battery Production with BPED Technology

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…

Sodium Sulfate Recovery from Ternary Precursor Production with BPED Technology

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…
