This graduation thesis deals with the reconstruction of the Mrzlek water treatment plant, which
supplies about 50,000 people with water. The water plant operates at the upper limit of capability and
barely suffices to cover drinking water consumption needs. Analyses of Mrzlek water source show
constant microbiological contamination and occasional increases in raw water opacity. Treatment
results sometimes do not meet the requirements.
The graduation thesis is thematically divided into two parts. The first part presents the technologies of
drinking water treatment, the existing water plant, water source and raw water analysis. The second
part provides three options for the reconstruction of the water plant. Each of the options includes
description of construction work and dimensioning of technological procedure. In the first two the
existing conventional procedure of treatment is improved, whereas in the third one the main
technological procedure is ultrafiltration, which is the modern way of treating drinking water. All of
the examined treatment processes are designed for the flow rate of 300 l/s. The graduation thesis
concludes with a recommendation of the most appropriate way of treating the Mrzlek water plant
drinking water.
