Concentrate Lithium Battery Wastewater and Recover Process Water
Customized evaporation, concentration and ZLD systems for selected high-salt and resource-bearing wastewater from battery-material and cell manufacturing.
Why This Wastewater Is Difficult
Recommended Treatment Approach
Treatment usually combines stream segregation, metal recovery or precipitation, ammonia and fluoride control, membranes and evaporation. Vacuum evaporation can reduce selected high-salinity wastewater or RO reject. Scraped crystallization may further minimize liquid discharge when mixed-salt behaviour has been confirmed by testing.
Suitable Applications and Important Limits
Applications vary widely between cathode materials, anode materials, electrolyte preparation, recycling and cell production. Solvent-bearing or reactive streams must be isolated and assessed separately; evaporation is not automatically suitable for every battery wastewater stream.
Actual performance depends on feed composition, operating conditions and the required reuse or discharge objective. Representative testing is recommended for complex or variable streams.
Technology Options
Low-Temperature Vacuum Evaporation — liquid-waste minimization and distillate recovery.
Scraped Vacuum Crystallization — further concentration of scaling, viscous or crystallizing feeds.
Integrated ZLD — pretreatment, evaporation, crystallization, separation and polishing.
Information Needed for Evaluation
Lithium, nickel, cobalt, manganese, iron, fluoride, ammonia, total nitrogen, sulfate, phosphate, chloride, COD/TOC, known solvents, TDS, pH, daily volume and recovery objective.
