Salt Concentration and Reuse in Chemical Industry
Lanran provides ion exchange membrane and BMED (bipolar membrane electrodialysis) technology for the chemical manufacturing industry, enabling efficient treatment of wastewater, particularly from pesticide chemicals and electrode foil production.
These technologies allow for the concentration of waste salt from wastewater streams and the production of valuable acid & alkaline, promoting resource utilization, reducing waste generation, and enhancing environmental sustainability.
Typical Project - The reclamation of NaNO3 from electrode foil wastewater
Process/Technique: Salt Recovery – Production of Nitric Acid and Sodium Hydroxide from Sodium Nitrate
Starting year: 2020
Production scale: HNO3 (purity: 100%), 15000t/y
Effluent: HNO3, 63g/L, about 30m³/h
Energy consumption: 1700-2200kWh/(t·HNO3)
