theory of the metabolic selection in biosolids, which describes
the driving forces of the elimination of nutrients.
The theory has been experimentally proved from him and
his co-workers. Prof. Wanner also worked on the topic of
population dynamics of microorganisms in sewage sludge
and the identification of bacteria in sewage sludge.
As mentioned by Mr. Peter Cook in his welcoming speech,
the high reputation of the Institute of Chemical Technology
Prague in the international scientific field is due to the
work of Prof. Wanner. The institute took part in other research
programmes in Italy, Austria, Hungary, and Australia.

William Dunbar – a Pioneer in the field of wastewater
The William Dunbar Medal has been sponsored by the
Munich Trade Fair Centre and awarded since 1973 by the
EWA every three years during IFAT. The prize consists of
one Golden Medal, Certificate and a monetary prize. The
medal is in memory of William Philipps Dunbar, born in
Minnesota (USA) in 1863, who came to Hamburg in 1892
due to dangerous cholera epidemics.
Dunbar developed further the method of identification of
the pathogens causing cholera and plague. His experiments
extended to the examination of the canalization and Elbe
waters, since the most common spreading paths of the pathogens
are the water. Dunbar researches were so fundamental,
that even today he is well known among the
wastewater treatment specialists.
