Assessment of the concentration and properties of dust in emissions into atmospheric air from the sources of the workshop for the aerated concrete structures production

Abstract

Abstract Improving the environmental safety of manufacturing enterprises in construction industry remains an urgent task today. The need to expand the research in this area is dictated by a wide range of industrial enterprises, a range of products, as well as the varieties of bulk raw materials used in the manufacturing process. Exceeding the maximum permissible values for the content of fine dust PM10 and PM2,5 in the atmospheric air, both on the territory of industrial sites and on the borders of sanitary protection zones, is due to the ineffective operation of the existing dust cleaning systems. Analysis of the dispersed composition of dust in emissions from the construction industry, as well as the study of dust properties depending on the type of enterprise, raw materials used, the characteristics of technological operations, are the basis for the development of measures optimal for a particular production to reduce dust emissions, improve the environmental situation in general.
