Study of Meltwater Treatment Using the Industrial Waste and Natural Sorbents

Abstract

Abstract In winter, a huge amount of snow contains the specific pollutants (anti-icing reagents, oil products, ion-metals and others) accumulates in the cities of the Northern Russian Regions. The special environmental requirements for operation and engineering equipment of the snow-landfills are not excited. In this case, the soil cover and nearby water bodies are contaminated by meltwater, and the engineering and geological conditions are changing at these areas. The specific composition of the snow masses requires the use of the special treatment methods to remove such major contaminants as oil products and chlorides. Currently, an effective and relatively cheap sorption material for the extraction of these pollutants from meltwater is being actively sought. In this paper, the sorption properties of the industrial waste (sawdust) and natural sorbents (kaolin, clay) were studied. The best results for the meltwater treatment from oil products and chlorides with kaolin were obtained. The sorption filter design, which is part of the proposed technological scheme for the meltwater treatment, has developed.
