Treatment of pyrazolone production wastewater - bipolar membrane electrodialysis process

2024-05-20

Ammonium sulfate in pyrazolone wastewater can be separated into sulfuric acid and ammonia water by bipolar membrane electrodialysis process, which can be used for production or export. After ammonium sulfate separation, the main pollutant components in wastewater are pyrazolone (with low salt content), eliminating the investment in evaporation equipment and realizing an efficient and energy-saving wastewater treatment process.
