Operation and optimization of a capacitive deionization unit
Vespalec, Jan ; Mergl, Václav (referee) ; Repková, Martina (advisor)
This bachelor thesis is focused on the extension of the information available so far on capacitive deionization within the framework of research activities in the field of separation methods. In the theoretical part, the laws of deionization, factors influencing the course of deionization, possible configurations of the capacitive deionization model, electrode corrosion issues, practical applications and future developments of capacitive deionization are discussed. The experimental part describes the capacitive deionization unit located at the FCH BUT, the procedure of electrode replacement, calibration of pH and conductivity probes and the optimal setting of factors influencing the course of deionization. In this bachelor thesis, a series of measurements were carried out to find the optimal setting of the unit.

Classification of concentrate from membrane processes
Vespalec, Jan ; Mergl, Václav (referee) ; Repková, Martina (advisor)
The Master’s Thesis deals with the classification of concentrate from membrane processes, specifically reverse osmosis concentrate. Membrane technology was used in two locations, namely a wastewater treatment plant location and an industrial laundry location. The reuse of water by using membrane processes requires consideration of the management of the concentrate further on. The concentrate may be concentrated to the point where it is not meeting the legally defined limits. The goal of this work is to determine whether reverse osmosis concentrate can be discharged to the surface water/sewage system and whether it is a hazardous waste or not. The conclusion of this work is that the monitored parameters occurring in the reverse osmosis concentrate are over the limits to be discharged to a surface water/sewage system but are below the limit for classification as hazardous waste.
