Groundwater Softening Materials Based on Natural Raw Materials

Abstract

The studies on water softening using sorbents based on modified sunflower husk and buckwheat are given. It is shown that these crop wastes can be raw materials for sorption materials for softening groundwater. The sorption capacity of the materials obtained under static and dynamic conditions for hardness salts was studied, a regeneration solution was selected, regeneration was carried out. The time of the protective action of the filter and the achievement of its full dynamic capacity by the method of GOST and the author's method are determined.
