There are analyzed various waste water cleaning methods of detergents. Froth formation in detergent leaches, dynamic and static stability of foams and basic information about froth devices are given. The characteristics of the suspended layer and its use in water treatment of detergents are given. The aim of this work – is to explore the suspended layer in cleaning waste water of detergents. Final work consists of seven parts: introduction; the subject matter and the problem description; water purification of synthetic detergents, characteristics of froth bubbles and froth formation, froth machines; suspended layer characteristics and the possibility of using it in waste water cleaning of detergents; experimental part; conclusions and references. Experimental part includes theoretically calculated suspended layer parameters, description of the experimental stand, its operating principle, instruments used during the experimental procedures, calculations of suspended layer variable settings according to the experimental data. In the end the results are analyzed and the conclusions are included. Thesis consists of: 67 p. text without appendixes, 21 picture, 4 tables, 24 bibliographical entries. Appendixes included.

This dissertation is concerned with the foundations in volume unstable soils and objects disorders which are related to this. The thesis was focused on the study of clay and loess soils which are abundant in the geological profile of the Czech Republic. First, the formation of the two groups of soils is introduced, then their properties are examined and finally the influence of vegetation on the former type and the influence of collapsibility in the latter type are investigated. The conclusion is, in fact, a recommendation on the design of structures so that the system of clay / structure is not damaged and that structures are not subject to renovations. Several instance of problems with structures are discussed which were subject to structural repairs employing both a civil and geotechnical engineers.
