Research:

The main professional interests include the study of biofilm processes, especially with regard to the stabilization of the nitrification process in the biofilm, the population dynamics of activated sludge, both the growth of microorganisms associated with biological removal of nitrogen and phosphorus, and the population dynamics of microorganisms affecting the separation properties of activated sludge, including description by mathematical models. For example, the method of bioaugmentation of nitrifying bacteria in-situ using the regeneration zone in the return sludge stream can be attributed to successful study of population dynamics. This method is used, inter alia, on both water treatment plants of the CWWTP Prague. He formulated the principles of metabolic selection to control the sedimentation properties of activated sludge in anaerobic and / or anoxic zone systems. It also deals with calculations and principles of the correct construction of modern settling tanks. Since 2008, the research activities of prof. Wanner focused on technologies that allow the reuse of purified wastewater as a substitute for river or drinking water. The importance of these technologies continues to increase with the risk of water scarcity due to drought and the ever-increasing price of drinking water. Prof. Wanner i in the Waste Water Treatment and Recycling Group of CzWA and the EWA European Technical and Scientific Committee.
