Water
Treatment at Fossil Power Plants and Highly Mineralized Waste Processing
This research field at TWT Department is guided
by Dr. Lyudmila
Vasina. It is related with development
of thermal method of processing of the highly mineralized water.
To provide reliable operation of heat-exchange
equipment (evaporators, heat exchangers), optimum water chemistries have
been developed on the basis of research on thermodynamics of solutions.
The produced test data on regularities of formation of difficultly soluble
compounds and developed method of calculation of scale formation rate have
provided their successful use at operating evaporators and desalination
plants.
The research group personnel participates in development
of up-to-date methods to prevent scale formation. One of these methods
includes feed of antiscaling compounds (in this country - phosphonates).
This method is in use not only during operation of evaporators, but also
in heating systems.
Scientific potential of the research group provides
solution of different water treatment problems. At present the work to
improve makeup pretreatment technology is underway. The properties of new
domestic and foreign coagulants and flocculants have been studied. New
technology of water clarification have been introduced at Mosenergo Power
Plant N 21.
Geography of facilities, where research results
of the group have been introduced, is broad enough, and includes regions
of Siberia, Transbaikalia, Kazakhstan, Ural, and Central Russian Upland
with different composition of water sources. Implementation of the research
results of the group helps to improve ecology situation in these regions.
