dc.description.abstract | Oily water is a generic term used to describe all waters with varying amounts of oils
and greases, as well as a variety of other materials in suspension. The process of
generating energy in a thermoelectric plant (UTE) produces several sources of
contamination, among them is the production of oily water. In this way, collecting,
storing and giving an adequate destination is part of the operational activities in a UTE.
There are several treatment methods for oily waters, such as gravitational vessels,
granular filtration systems, flotation by induced or dissolved air, centrifugation, use of
hydrocyclones, among others. Among these methods some treatments have been
highlighted as the process of dissolved air flotation (FAD). After careful review of the
literature, this work carried out experiments to identify correlations between FAD
kinetics and the velocity of foam removal in a flotation chamber, i.e. flotation velocity.
For this, statistical methods of non-linear numerical regression were used, comparing
mathematical models of FAD. A correlation was then identified for the rate of foam
removal from a flotation chamber, the mean value of which was between 13,09 m/h.
Thus, it was shown that information on mass transfer mechanisms can contribute to
cost reduction in FAD camera projects. | eng |
