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 make wastewater treatment more difficult. They also increase the cost of salt disposal.

❌ Lost water recovery opportunities — Without effective salt recovery, plants may lose valuable water and resources.

♻️ LANRAN BPED technology helps turn waste into value.

First, electrodialysis (ED) concentrates sodium sulfate (Na₂SO₄) from wastewater. Then, bipolar membrane electrodialysis (BPED) converts it into reusable sulfuric acid (H₂SO₄) and caustic soda (NaOH).

This process helps textile manufacturers:

🔹 Recover useful chemicals and reduce the need for fresh acid and alkali.

🔹 Improve resource recovery and support wastewater reuse.

🔹 Reduce salt waste and move toward more circular production.

Don’t just treat textile wastewater. Recover more value from it with LANRAN BPED.
