Design and development of an innovative laboratory setup for the restoration of dynamic activity in spent zeolites

This work presents the development of an innovative laboratory installation for the regeneration of spent zeolites used in the purification of natural and wastewater from heavy metal ions and other pollutants. The technological scheme of the installation is described, enabling efficient restoration of the dynamic activity of zeolite sorbents, which ensures their multiple reuse and reduces dependence on imported synthetic sorbents. The possibility of reusing eluates obtained during regeneration as components of electrolytes for electroplating processes is considered. The technical characteristics of the installation are provided, and the application areas of regenerated zeolites are described, including gas stream purification, fuel drying, and transformer oil dehydration. The expected effect of implementation is the optimization of regeneration modes, reduction of waste, and an increase in the environmental safety of production processes.
