7. Effect of ozone on dental caries and on cariogenic microorganisms
Sammanfattning : There are a number of unanswered questions regarding new caries preventive methods such as ozone treatment as well as novel caries detection methods that monitor and evaluate these preventive methods. This thesis seeks answers to some of these questions. LÄS MER
8. Application of ozone in wastewater treatment : Oxidation of pharmaceuticals and filamentous bulking sludge
Sammanfattning : As pharmaceutical removal was not part of the of the modern wastewater treatment plant (WWTP) design, it is not surprising that WWTPs have been identified as major point sources of pharmaceuticals entering the environment. The oxidation of pharmaceuticals in the WWTP effluent is one of the-end-of-pipe solutions that are considered most ready for full-scale use. LÄS MER
9. Oxygen formation in the chlorate process and preparation and deactivation of ozone selective anodes
Sammanfattning : This thesis presents experimental studies concerning two differ-ent electrolytic processes. One part deals with the electrochemicalformation of ozone and focuses on the preparation and deactiva-tion of a highly ozone-selective metal oxide anode (NATO - nickeland antimony doped tin oxide).
