EVN ordered the planning and erection of the mechanical, electrical and control system parts of a water treatment plant with membrane technology (ultra-filtration and low pressure reverse-osmosis) and activated carbon filtration.

In the new erected transition camber Mauer two systems for disinfection of drinking water of the second Viennese mountain spring water main were constructed. The first disinfection step is carried out with 4 pieces UV-disinfection plants.

Located on „Burgauberg“ an iron, manganese, ammonium and arsenic preparation plant was built for the „Wasserverband Thermenland in Stegersbach“. The plant with a capacity of 15 l/s secures the necessary disinfection with an UV-system. Both the mechanical and the electrical equipment has been delivered and …

In the framework of the research project “KLEIN AOP” scientifically conducted by the Technical University Vienna (TU-Wien), an AOP treatment plant (Advanced oxidation within ozone and hydrogen peroxide) was installed. With this plant organic pollutants (like tetrachloroethene) in drinking water can be efficiently reduced. The …

This is a treatment plant for the elimination of iron, manganese and ammonium exceeding the limit values for fresh water and to keep the carbonate/acid equilibrium. The final step of the technology is a UV-desinfection. The plant is run in two lines with a entire …

Iron and manganese concentrations of the fresh water are reduced in a three-line treatment plant in order to comply with the legal limit values. In an additional activated carbon filter Atrazin (pesticide) is eliminated. The capacity of the plant is 3 x 15 l/s. The …

The fresh water treatment plant was already built in 2004, consisting of filters to reduce iron and manganese, and included an activated carbon filter to eliminate pesticides. Fresh water tests show a high geogenic background concentration of uranium. Therefore, the treatment plant was improved by …

For the remediation of the site hydraulic measures including extraction and infiltration wells were installed. The highly contaminated flow of the extracted water is separated from the stream with low contamination and both streams are treated in the plant. The system consists of pre-aeration and …

A drinking water treatment plant operating activated carbon filters was constructed to eliminate atrazine. The scope of supply includes process engineering, detailed design, whole mechanical equipment, electrical equipment, measurement technique of the plant. Moreover, the start-up and the proof of the guaranteed values during the …

EVN Wasser GmbH built a drinking water treatment plant in Drösing to reduce nitrate, water hardness and uranium. The two-line plant with a capacity of 60 l/s consists of membrane filtration technology and deacidification units. For security reasons, a part of the input water flow …
