Abstract

In the Master’s Thesis “Pre-investigation of Stormwater Quality at Metals Scrap Processing Plant” the literature review of 136 sources was performed with the focus on storm water pollution, physical and chemical properties of specific pollutants, origins of the pollution and pathways of the pollutants transport to the environment. Types of industrial storm water samples and sampling methodologies are described as well. Raprinfall data calculation are performed for the design of industrial storm water collection and treatment systems. The comprehensive analyses of storm water treatment are done. The experimental part of the work was carried out at the metal scrap processing industry with paved and unpaved aeries of the surfaces. During the research the industrial storm water screening characterisation was done at different locations of the whole territory. The treatment technology, including the sedimentation tank, retention tank and filtration trench was selected and calculated for the treatment of storm water of the investigated industry. The generalized conclusions and results of the work can be useful for state institutions, research institutions and the enterprises engaged in storm water management.
