Optimization of operating parameters in drinking water treatment plant in Bzenec-Přívoz
Sukopová, Martina ; Mergl, Václav (referee) ; Mega, Jaroslav (advisor)
Water treatment plant Bzenec Přívoz represents important supply of potable water for Hodonín district. After a longtime operation it was in 2008-2010 reconstructed in order to make water treatment technology more effective. The basic step was dividing technology into one stage and two stage water treatment for particular spring areas of ground water. The character of raw water requires effective removal of iron and manganese, therefore intensification and optimization of operating parameters were the purposes of the project. Installation of new aerators and hyperboloid stirrers in flocculation tank required an operating tests for proving of high technological efficiency while the operating costs were decreased. The water treatment process was completly automatized, which made the operation easy and minimized human element impact. Results of the reconstruction are more effective water treatment and a distinct decrease of operating costs.

Reconstruction of Water Treatment Plant Babice
Valchař, Jiří ; Roh, Robert (referee) ; Kučera, Tomáš (advisor)
This study deals with a reconstruction of the water treatment plant. The First chapter gives a brief overview of iron and manganese common removal methods. The next chapter looks at technical condition evaluation of urban water networks and presents a new methodology TEA Water developed by Brno University of Technology, module TEAT-Water Treatment Plants in particular. Following chapters describes local water distribution system and current condition of the water treatment plant. The main aim of this thesis is to choose the best suitable technologies for water treatment in order to reduce high operating expenses, especially energy consumption and to reduce volume of backwash water.

Removal of iron and manganese in water treatment process
Šafaříková, Jana ; Hnaťuková, Petra (advisor) ; Pivokonský, Martin (referee)
This diploma thesis is aimed at the evaluation of water treatment technology in Písty waterworks which treats raw water with high concentration of iron and manganese. The most common method of iron and manganese removal from raw water is based on oxidation to insoluble hydrated oxides followed by separation of formed aggregates. The plant technology consists of aeration, oxidation agent KMnO4 dosing and mixing, sedimentation, filtration and hygienic protection. Chemical analysis of treated water, evaluation of the aeration efficiency of iron and manganese oxidation, evaluation of the separation efficiency of the sedimentation tank and filters, assessment of distribution of iron and manganese in the filter, assessment of dirt holding capacity and optimization of KMnO4 dose were determined. Raw water pH fluctuated around 7,3 during measurements, whereas iron and manganese concentrations in raw water were 6,00 and 0,82 mg.l-1 , respectively. Oxidation of 97,2 % of dissolved iron and of 14,3 % of dissolved manganese was achieved after the aeration. The separation efficiency of the sedimentation tank was 82,9 % for iron and 46,5 % for manganese, however the separation efficiency of the second half of the sedimentation tank was low. Thus, the perforated baffles in the second half of the sedimentation...
