Methods for separation of ammonia from waste water
Zendulka, Štěpán ; Touš, Michal (referee) ; Vondra, Marek (advisor)
The main concern of this thesis is to provide a comprehensive overview of methods for ammonia separation from wastewater that have been discovered so far. The elementary differentiation is based on technological principle – biological and physical-chemical. Also, the thesis examines all methods from the „conventional or progressive“ point of view, which shows if the method is commonly used or is still in an experimental set up. Furthermore the focus is on classification of methods on „eliminating ammonia“ or „recovering ammonia“. This is closely connected to the economical aspects of each method which is also one of concerns of this thesis. Some of the methods are described with further details as there has been a recent progress and upgrading of these methods. It is air stripping and membrane methods. More attention is also provided to bioelectrochemical systems as it is proclaimed as one of the most suitable candidates for usage in the future. Last part of this work compares selected methods in terms of the ammonia elminiation or recovery efficiency and also power demand.

Liquid-vapor mass exchange in stripping processes
Liman, Martin ; Kalivoda, Josef (referee) ; Svěrák, Tomáš (advisor)
This diploma thesis deals with the solution of ammonia separation from waste raw materials of agricultural production. It focuses on determining the efficiency of desorption from an experimental stripping device depending on the measurement temperature. Ammonia water solutions and liquid digestate samples from technical practice were used to verify the functionality of the equipment. Increasing separation efficiency with increasing temperature has been demonstrated. The device was gradually improved during the measurement for a better profitability of the separation process. The results of the experiments are discussed concerning the theoretical assumptions and compared with other methods of ammonia separation.
