Intensified Technology of the New Type Potassium Fertilizer Production.
2020
Soil is the important component of the ecological system on the basis of which plants grow making in their turn an important link in the food chain. In restoration of soil fertility the various fertilizers are used among which potassium fertilizers are important. We have researched the method of potassium fertilizer production with use of wasteless, ecologically poor technology. The fertilizer is produced with the non-traditional, combined sorption and membrane method, where the Georgian natural zeolite-clinoptilolite is used as substrate and the Black sea water as a potassium ions source. Also we used electrodialysis for preliminary concentration of seawater. We have matched and developed the optimal parameters of operation of electrodialysis apparatus providing excess of potassium concentration indexes over the same for the other ions. The method is prospective for the countries of the Black sea region with deficit of potassium fertilizers and availability of the recourses of zeolites.
