Abstract

Application of flotation in the decontamination of sediments from the Cerny prikop stream The stream Cerny prikop is located in the Ostrava city districts of Marianske Hory, Moravska Ostrava and Privoz. This locality belongs to the most polluted areas in Ostrava as it is unbearably polluted by the Coking Plant of Jan Sverma, company BorsodChem MCHZ (the chemical plant), City Waste Water Treatment Plant and a number of other companies in the given territory, all the way to its mouth to the Odra River. Moreover, the area is also affected by the construction of the D 47 motorway. The sediments of Cerny prikop represent a significant ecological burden within the Ostrava urban area. They are contaminated by a wide range of organic pollutants which have never been exactly identified.
