Petrochemical & Power Plant
Lanran Tech applies conventional Electrodialysis (ED) to pre-concentrate lithium from salt lake brines or lithium ore leachates.
Description
Petrochemical and thermal power industries generate saline wastewater (e.g., FGD wastewater, process brines). Lanran’s ED and BPED technologies achieve deep desalination, concentration, and resource conversion, supporting zero-liquid discharge.
Process
- Wastewater is pretreated and softened.
- ED produces reusable water and concentrated brine.
- Concentrated brine enters BPED or crystallization to produce acids, alkalis, or solid salts.
Applications
- Petrochemical brine management
- Power plant flue gas desulfurization (FGD) wastewater treatment
Key Advantages
High water recovery efficiency
Converts pollutants into valuable chemicals
Lower operating costs vs. evaporation-only methods
