Control unit for automatic laboratory manipulation system
Vávra, Tomáš ; Růžek, Václav (referee) ; Dřínovský, Jiří (advisor)
This document deals with devices which are used for the automatic Gram staining. The document starts by a research with the aim to discover existing devices and to compare them to the concept of the device developed by company Biovendor. There is theoretically and then practically dealed with the methods of the rotor imbalance detection and measurement of water-level. The Practical part of this document describes the development of the control unit with the microcontroller ARM Cortex-M3 which will be used for the prototype development of Biovendor’s device. The Last part describes measurement of imbalance of three different rotors with the aid of the control unit.

Design of Laboratory Centrifuge for Sample Separation
Kašná, Marie ; Rubínová, Dana (referee) ; Fridrichová, Eva (advisor)
The project deals with the design of laboratory centrifuges with regard to aesthetic, ergonomic and technical parameters. Emphasis was placed on stability, ease of use and further possibilities for use. The project also includes an analysis of the current market. The resulting device design can be widely used, but is most suitable for small laboratories.

Equipment for the enrichment of nuclear fuel
Ostrezi, Matěj ; Martinec, Jiří (referee) ; Suk, Ladislav (advisor)
The aim of this bachelor thesis is to review the current knowledge and possibilities dealing with an enrichment of the nuclear fuel and to describe particular methods of the enrichment. An attention is paid to basic principles, functions, technological and power requirements and efficiency of the discussed methods. In conclusion, a difficulty of the enrichment process is pointed out and a balance sheet of the economic impact is made.

Dependence of Sludge Dewatering efficiency on amount of flocculant
Volejník, Tomáš ; Medek, Jaroslav (referee) ; Boráň, Jaroslav (advisor)
The target of the first part of this diploma thesis is focused on the problems relating to the sludge production from the wastewater treatment plant and subsequent sludge treatment. Wastewater treatment plant and individual processes from the sludge management are described. The process of the sludge dewatering is described more extensively. Various methods of the dewatering and materials balance are described, too. The second part of this thesis is based on the experiment which took place on wastewater treatment plant Tetčice. The influence of the polymeric organic flocculant dosing on the sludge dewatering was monitored by this experiment. Dependence of the sludge dry matter and filtrate suspended solids content on the specific amount of flocculant was evaluated from experiment’s outputs. Using materials balance and outputs of the experiment, economical balance was made. It made possible to choose the most economic and technologically optimal way of the sludge dewatering on wastewater treatment plant Tetčice.

Hydrodynamic separation water flow sediment
Sajner, Pavel ; Neterda, Zdeněk (referee) ; Němec, Zdeněk (advisor)
The dissertation deals with clogging of reservoirs and ponds by redundant sediments which penetrate water system by erosion. It describes methods of extracting pond sediments. It contains measurement of dewatering of sediments on hydrocyclone and design of laboratory hydrocyclone and filter unit. In the conclusion there is design of technology of dewatering sediments which were extracted by wet method by drainage excavator. Numerical simulation of flowing in hydrocyclones is simulated in the CFX programme and dewatering technology is simulated in the CHEMCAD programme.
