Among other positions, he headed the ATV technical committee 2.6 "Aerobic biological wastewater treatment processes" (later name: DWA technical committee KA-6 "Aerobic biological wastewater treatment processes"). This committee, with his significant participation, drew up the guideline ATV-A 131 (1991), in which the technical rules for the selection of the most appropriate methods for the elimination of carbon, nitrogen and phosphorus in wastewater treatment plants as well as for the design of the main plant components and equipment are compiled. Based on these rules and regulations, wastewater treatment plants with a

At TU Wien, the "Workshop on Design - Operation Interactions at Large Treatment Plants" was held and organized at his suggestion in September 1971. This was the first conference on this topic of the IWA (at that time: International Association on Water Pollution Research, IAWPR), which is active worldwide today. Wilhelm von der Emde was also active at the German Association for Water Management, Sewage and Waste (DWA -

This plant attracted great international attention, as it was one of the first large-scale plants in the world to be able to remove not only organic contaminants but also nitrogen compounds to a large extent in the same tank by biological means. Also, essential parts of the functional concept of the later main wastewater treatment plant in Vienna (

production as well as the chemical industry, which were responsible for a substantial part of the pollution of water bodies in
Austria. In many cases, new wastewater treatment processes were developed from laboratory tests to the operation of large-scale plants. A typical example is a process developed in the 1980s for the purification of wastewater from citric acid production by the company
166:. Further fields of his broad spectrum of activities included the training of operating personnel of wastewater treatment plants. He initiated the establishment of corresponding training networks and participated in their organisation in a leading position. His work provided the central basis for concepts of water protection and for maintaining and improving water quality.

From 1949 to the end of 1952 he worked in Dietrich Kehr's engineering office, and from 1953 to 1958 he was assistant and senior engineer at the Institute for Urban Water Management at the Technical University of Hannover (Director: Dietrich Kehr), where he received his doctorate on 10 July 1957.

Equally exemplary was the work of
Wilhelm von der Emde and his team in reducing and preventing the eutrophication of water bodies. The main focus here was the avoidance of phosphorus inputs into Lake Constance and Lake Neusiedl. The measures initiated and implemented were extremely successful and are

and from April 1961 onward he also lectured at the
Technical University of Delft. During a stay in England (Manchester) he met William T. Lockett, one of the inventors of the activated sludge process. In 1914 Lockett, together with Edward Ardern, had invented the activated sludge process based on the

In his dissertation, he described the state-of-the-art of the methodology for dimensioning wastewater treatment plants at that time and developed a new procedure to calculate the oxygen consumption and excess sludge production of aeration plants, which is still used today in a slightly modified form.

Von der Emde recognised very early on, that the objectives of water protection can only be achieved if pollution by industrial wastewater is largely avoided. Under his leadership, the institute, therefore, dealt intensively with the treatment and disposal of wastewater from leather, pulp and sugar

In addition, Wilhelm von der Emde was committed to the training of qualified personnel for sewage treatment plants at a national and international level. Thus he was in a leading position in the development of today's training program of the
Austrian Water and Waste Management Association (Ă–WAV -

In the field of river basin management, Wilhelm von der Emde researched the relationship between wastewater treatment and water quality. In practice, the results led to improved water protection and a considerable increase in water quality, not only in
Austria. For example, the "Danube Expert
