My passion for water, sewage and environmental protection

Water can be described as the most precious resource on earth. It is the basis of life for plants, animals and people, be it as drinking water or to create living space. Water in bodies of water or as groundwater is important for our habitat. Groundwater in particular should be subject to the highest level of protection, since it is only possible, if at all, to remediate polluted groundwater with great effort. The precautionary principle is therefore immensely important.

  • - I can actively contribute to the above tasks
  • - The combination of science and sales is exactly "mine".

It is hardly possible to list all the professions that deal with water. Water experts work, for example, at universities and research centers, at state and municipal institutes and offices, at water-related associations and water supply companies or the innovative companies that manufacture and sell water technologies. 

Water experts are sought after in energy supply companies, water and soil associations, state or private research institutes and last but not least in industrial companies or engineering offices. An important field of activity is drinking water treatment. Iron(II), manganese(II) and ammonium usually have to be eliminated from groundwater, algae and other suspended matter have to be removed from lake and dam water and ultimately the water must not be “aggressive” towards materials. Disinfection processes for hygienic safety are also part of the research areas. Drinking water quickly becomes waste water. 

Water chemists deal with many substances used in households, industry and agriculture such as sweeteners, pharmaceuticals and pesticides. Of course, the chemists are not satisfied with the analysis, but try to show ways of reducing the pollution of our waters. 

The meanwhile established nutrient elimination in sewage treatment plants would not have been possible without the cooperation of water chemists. The introduction of more extensive wastewater treatment using activated carbon sorption or ozonation is currently an important topic in water chemistry. 

After all, modern industrial production and energy supply are also inconceivable without water. After fuel, water is the second most important resource for operating the water-steam cycle in large-scale power plants. And the quality requirements there far exceed those of drinking water, as in modern chip production. Ensuring and checking this requires knowledge of water chemistry. In industry in particular, the need for appropriate specialists is growing, as people are increasingly looking for solutions that make production processes more efficient and protect the environment, for example through increased recycling and reuse of water.

Why I Am Different

Inquisitive generalist

A lot of water is required in industry and is contaminated by a wide variety of pollutants within the most diverse production processes. Unfortunately, most of the industrial wastewater is wasted. Industrial wastewater is not just industrial wastewater. Municipal wastewater also places the highest demands on treatment and requires specific pre- and post-treatment. The applications for municipal and industrial water treatment and wastewater treatment are as diverse as the industries are. The goal is always the same: the contaminated or untreated water and waste water is treated in such a way that it can be (re)used directly or in a production process. It is my passion to develop industry-specific, individual solutions for optimal processing

Within a very short time, Stephan developed a concept that could hold back 99.9% of all zebra mussels.

Barbara H / David L
Project Manager / Technical Director (Refinery DE)

With his amazing background knowledge and experience, Stephan was able to optimize our trickling filters and find the problem in operation and process.

Arun N
Project Manager (Municipal Wastewater Treatment Plant UAE)

Stephan helped us a lot to fight against cryophyll bacteria. Now we have a good and reliable solution.

Henry B
Technical Manager (Dairy DE)

Mr Jakobs optimized our steam boiler. We save around 6000 euros per year in treatment chemicals.

Simone B
CEO (Laundry DE)

Mr. Jakobs developed a completely new technology for removing impurities from waste water with a high COD content.

Karl M
Technical Director (Industrial Wastewater Treatment Plant Belgium)

With a new technology we can now secure the drinking water supply in urban areas in Egypt.
