As the world’s population continues to grow, so does the demand for food and increased agricultural output. To this meet demand, high-quality fertilizers are required to produce high crop yields. Muriate of Potash (MOP), also known as potassium chloride (KCl) or Potash, is a common and valuable fertilizing agent used in agriculture to provide plants with the essential nutrient potassium needed for plant growth and development.
The wastewater generated during the Potash production process is highly saline and contains high concentrations of dissolved solids, potassium, and other impurities. Proper treatment is required to remove these impurities and reduce the salinity before discharge or reuse. Aquatech’s wastewater treatment technologies help Potash producers ensure sustainable production and responsible management of water resources.
Mine deposits, solution-mined deposits, and lake brines containing CaCl2 and/or MgCl2 are typically processed using flotation, evaporation, and crystallization systems to produce a MOP product of 95% KCl purity. The evaporation and crystallization system comprises forced circulation NaCl crystallizers and DTB potash crystallizers. The purge liquor from the NaCl crystallizer is processed by multi-stage DTB flashing crystallizers. The system’s design is optimized based on the feed brine composition, the product specification for purity, crystal size, as well as utility availability and costs and other factors.
