Abstract

The presented Thesis deals with the matters relating to oil substances removal from waste water produced by Steel Plant. Such water is mostly re-circulated and used as circular water. Thus, such water serves as a cooling medium within technological processes. The Introductory part of the Thesis defines the structure of water management of Steel Plant, whereas the second part specifies waste water and its contamination by contaminants. Next chapter specifies circular water circulation in the Tube Rolling-mill including oil substances occurrence and their removal from water circulating in the circuit. The following part of the Thesis describes fundamental principles of industrial waste water pre-treatment and Final part of the Thesis presents the proposal for possible solutions for oil substances collection from surface of scale pit.
