Electrodialysis Solution for Ammonium Nitrate Condensate Treatment
Background：
In ammonium nitrate production, condensate wastewater is generated during the evaporation process. This stream typically contains high concentrations of ammonium nitrate, has a relatively simple composition, and is produced at elevated temperatures. While it poses environmental challenges if discharged directly, it also offers strong potential for resource recovery.
Lanran applies membrane electrodialysis (ED) as the core technology to efficiently recover ammonium nitrate and reuse water from the condensate stream, while avoiding secondary pollution and reducing overall energy consumption.
Lanran Solution：
Lanran implemented a membrane electrodialysis–based treatment system, with electrodialysis (ED) as the core process, supported by pretreatment and electrodeionization (EDI).
Pretreatment ensures stable operating conditions by adjusting pH, controlling temperature, and removing suspended impurities.
Electrodialysis (ED) selectively separates and concentrates ammonium nitrate under a DC electric field, enabling efficient recovery.
Electrodeionization (EDI) further polishes the desalinated water, allowing it to be reused within the plant.
The recovered ammonium nitrate solution is returned to the production process, while the treated water is reused as circulating or process water.
Key Technology Advantages：
High-efficiency recovery of ammonium nitrate and water
Lower energy demand compared with evaporation-only solutions
No chemical regenerants, avoiding secondary waste
Stable operation under high-temperature and industrial conditions
Reduced operating costs and improved overall process efficiency
Proven Industrial Application：
The system has demonstrated long-term stable operation in multiple ammonium nitrate plants. By integrating electrodialysis with advanced water treatment processes, Lanran’s solution helps our clients achieve clean production, reduced wastewater discharge, and circular resource utilization, delivering both environmental and economic benefits.
