Development of Natural Zeolites Regeneration Scheme

In this paper, the research results on the adsorption process of final treatment of wastewater from electroplating production using a model filter with a nominal capacity of 0.3 m3/h are presented. Natural zeolite of the Trans-Baikal deposit heulandite was used as a charge. The processes of sorption and selective desorption of heavy metal ions were studied. Based on the results, the natural zeolites regeneration scheme was developed; the scheme provides the multiple reuse regenerated adsorbents in the processes of final treatment of wastewater from electroplating production, and eluates produced by regeneration can be reused in the manufacture as components for electrolytes used for electroplated coating deposition.
