Use of recycling membrane technology for industrial waters
 Vykydalová, Adéla ; Mergl, Václav (referee) ; Repková, Martina (advisor)
The bachelor thesis deals with the recycling technology of industrial wastewater – more precisely, the laundry industry. The semi-operational pilot unit of ASIO TECH was used for testing this technology. The unit includes membrane processes – ultrafiltration, reverse osmosis and flotation process. There were 8 physico-chemical parameters selected for assesing the quality of wastewater and treated water. The tested semi-operational unit is suitable for cleaning laundry wastewater. The purified water can be used in the next washing process or for the water source for the steam generator.

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.
