Project news

By means of holistic optimization, Waste Water Treatment Plant Aachen-Soers has succeeded in reducing the enormous energy demand of the recovery by around 55 per cent. Together with DAHLEM, the Wasserverband Eifel Rur planned the modernization of the oxygen supply of the aeration tanks. The design was implemented at the beginning of the year, followed by the commissioning of the blower station mid-year. The RWTH Aachen accompanies the project scientifically. DAHLEM supported the process design, which was modeled in a 3D-planning and accompanied the award procedure. The enclosed article about the project provides detailed information about the modernization of the plant. The waste water treatment plant is also referred to as a nationwide model Enterprise.

There was much enthusiasm at an unusual design meeting on the extension of WWTP Kleve-Salmorth, which is soon to be launched as a thermo-compact plant: plant manager Michael Offenberg and his team from the Kleve-based environmental operations were able to see how it felt in the new buildings of the waste water treatment plant. Is there enough space between the plant parts? Can one move well in between? Are there any missing components, etc. With the help of VR glasses, Torsten Wach, who is in charge of the project coordination, guided the participants through the building model, which was projected directly onto a screen. It made it possible for all involved to point out errors or changes and to rectify them before the start of construction. WWTP Kleve-Salmorth is regarded as a flagship project for innovative sewage sludge treatment and meets the requirements of the new Sewage Sludge Ordinance for Waste Water Treatment Plants to reclaim phosphorus from municipal sewage sludge in the future. Thus in the long run, the supply of this nutrient, which is central to all organism, shall be ensured. DAHLEM provides the design services, from the initial conceptual design to the award, including construction supervision.

Future-oriented flood prevention is a big topic worldwide. How it actually works is what the employees of SIGN, the Chinese-German Water Network, wanted to see for themselves on site in Germany. Dipl.-Ing. Holger Ackermann, employee at DAHLEM in Essen and member of the research project, led the Chinese delegation to various locations such as, for example, the ThyssenKrupp site, the Oberhausen pumping station and the Holtener Feld, designed and supervised by DAHLEM primarily taking into account the rainwater management aspects. As part of a subproject recommended for implementation, namely "Urban Water Management for Future Cities", DAHLEM developed a locally applicable action plan for future-oriented flood prevention in China together with SIGN, the Chinese-German Water Network.

Company News

Since the start of the woman's promotion programme ChanceMINT.NRW of the University of Duisburg-Essen, female students have been visiting DAHLEM Engineering Office. The female students at the Department of Civil Engineering, Electrical Engineering and Energy Systems are preparing for a career path that is highly male influenced. This year seven female students, together with two project coordinators, got an idea of the practical daily work process here. Jana Sommer, who designs sewage engineering systems as an engineer at DAHLEM, looked after the group and talked about her professional work routine. "It brings me great joy to inspire the female students for the versatile and interesting job of an engineer at an engineering office". In October 2013, the University of Duisburg-Essen started the program ChanceMINT.NRW for female students of natural sciences and engineering disciplines. The programme offers them the opportunity to gain networking and future-oriented practical experience in numerous workshops. Corporate advisors allow female students in the first three semesters to prepare for their professional entry and future career. Gregor Dahlem is involved in the programme as a corporate advisor: "Our employees are our most important asset. In order to promote young engineers at an early stage, we are glad to get involved with ChanceMINT.NRW."
 

Creating a flower meadow together: under the expert guidance of a landscape gardener, Young and old prepare the area for the new flower Meadow on the garden plot of DAHLEM. The employee´families were also invited. The kids had particularly a lot of fun energetically removing the turf, raking and sowing the seeds. With a smile, Jan-Gregor Dahlem tells us that his five-year-old son remembers this experience so well that he still speaks of the flower Meadow at kindergarten. The intense commitment to nature was subsequently with a hearty snack.

It is meanwhile the 9th Essen company run that the DAHLEM running community can register. Again it was said: Together - for each other. A highly motivated Dahlem Team, which meanwhile also consists of our employees´children, started again. "Being here and arriving is our motto." From 19:00 o'clock on, the starting line filled up with the runners at Huyssenallee. The route could be covered by running or walking. It was not the competition between the companies that took place there; everyone came together to make the most of the sporting event with great fun and dedication. The popularity of the Company run is unbroken - from year to year, more participants take part. In 2019, around 11.000 athletes ran to the finish line.
