The global water shortage is a challenge for modern society. Wastewater could
be used as a potential source of water, but it must be properly treated before it can be
used. Due to the persistence of some pollutants, advanced oxidation processes may be
used in parallel with conventional water treatment processes.
The aim of this work was to test one of the advanced oxidation processes - semiconductor
photocatalysis. I synthesised three types of solutions with titania nanoparticles to coat
millimetre-sized granules and test their photocatalytic activity. I also tested the process
of thermal treatment of the granules with the coating. The influence of oxygen purging
during the photocatalytic measurements was also tested.
