Abstract
Production of Potassium-Enriched Fertilizer Using the Complex Sorption and Membrane Technology
Highlights
In the last decades, the scientists’ attention has been focused on the new technologies, as well as the use of non-traditional raw materials for production of potassium products, which is caused by the deficiency of potassium mineral fertilizers [Fao, 2019]
Cheapness and availability of the raw material make this method very interesting and prospective for the countries with clinoptilolite stocks, located in the seaside regions and engaged in agrarian industry (Georgia, Greece, Romania, Bulgaria)
The optimal parameters for concentration of sea water were matched using the electrodialysis apparatus produced in the Institute workshop
Summary
The scientists’ attention has been focused on the new technologies, as well as the use of non-traditional raw materials for production of potassium products, which is caused by the deficiency of potassium mineral fertilizers [Fao, 2019]. In Georgia, this situation determines the viability of production of a new type of fertilizer – potassium-enriched zeolites [Okudjava et al, 2008, Beruashvili et al, 2008]. Due to the strictly determined dimensions of pores and inner cavities, they are good adsorbents for many inorganic and organic substances [Mumpton, 1999]. They have the unique physicochemical properties and comparatively low cost, which provides the potentiality of using zeolites in the technological processes designed for solving of some tasks of nature protection [Shimzu et al, 2007, Vilcek et al, 2013, Girijaveni, 2018, Rasyid et al, 2021]
