Abstract

Development of cheap and reliable methods of water purification is worldwide challenge. Application of sorbents is one of the most efficient and universal method of water purification, but it has drawbacks. Designing of new efficient sorbent is topical task. The main goal of this study was investigation of the new sorbent based on the aerated concrete. The aerated concrete sorbentwas used in intact condition and after modification. The composition of thesorbents was determined by elemental analysis with emission spectroscopy. Zeta potential of water suspension was evaluated by Zetasizer Nano. The low leaching level into water for all tested sorbents was determined. The properties of the filtering materials have been determined by sorption test of removing bacteria Escherichia coli from the model suspension. The surface parameters were investigated, using the method of thermal desorption of nitrogen. The tested filters with fraction of less than 0.1 mm clean the bacterial suspension to the level of compliance with hygiene standards for drinking water. It was revealed satisfactory properties of the filtering material for water purification from microbiological contaminations. The results prove the possibility of using the aerated concrete for water purification.
