Wastewater quality arouses interest among students

Maintaining and improving the wastewater quality worldwide is one of the greatest challenges of our time. PPU Umwelttechnik GmbH has taken on this task. Since 2008, it has been producing wastewater treatment solutions for the industrial, decentralised, municipal, and private sectors. The company wants to pass on its experience to young people. Students are given the opportunity to gain in-depth insights into wastewater technology research. Through final theses in the field of environmental technology, they can learn about the topic of wastewater quality and the associated advances.

How does PPU Umwelttechnik GmbH improve wastewater quality worldwide?

Difficult access to clean drinking water is a major problem in many parts of the world. One consequence is the increasing spread of diseases. A lack of wastewater technology and the resulting poor wastewater quality make for difficult living conditions and pollution of the environment. PPU Umwelttechnik GmbH produces and develops wastewater treatment plants that are specially adapted to local requirements. It exports easy-to-operate plants, some of which operate without electrical power, to numerous countries.

PPU Umwelttechnik GmbH addresses each type of wastewater individually to find a suitable solution for each customer. The Research & Development department of PPU Umwelttechnik GmbH takes care of the constant further development of the systems in wastewater technology.

Final theses in the field of environmental technology enrich students

In recent years, some students have written their research or final theses together with PPU Umwelttechnik GmbH. This gives them direct insights into industrial wastewater treatment. Detailed analyses of specific projects prove helpful in enabling the optimal adaptation of each plant.

Use of small wastewater treatment plants for pre-treatment of surplus water from biogas plants

Biogas plants are a practical tool for utilising biomass and generating energy from it. Unfortunately, there is always some risk to the environment. Untreated wastewater can contaminate the groundwater, either through precipitation or leaking parts of the plant. This makes adequate wastewater treatment more important, which Stefan Decker investigated in his work. He was able to show that model plants remove some impurities and that the required bacteria can grow better.

Growth behaviour of biofilms on plastic bodies for wastewater treatment and their influence by common household cleaning agents

Henrike Stockel’s work investigated how well a biofilm can grow on different types of plastic. She found that the material does not have much effect on the growth of the microorganisms. Another point of the work was the effect of cleaning agents in wastewater. From the analyses, it was found that the cleaning agents do not have a harmful effect on the biofilms. However, alkaline detergents pose a problem. They change the pH value, which affects the microorganisms and thus impairs the wastewater quality.

Micro sewage treatment plants for decentralised use in the subtropical climate zone

Every country in the world has different living conditions and standards. But the need for wastewater treatment exists everywhere. In his final thesis, Thomas Rampf looked at the situation in the West African country Benin and investigated how sanitation can be improved there. Due to the unsecured power supply, a non-electric sewage treatment plant is often the best solution.

PPU Umwelttechnik GmbH is available to help any student writing a thesis in the field of environmental technology. We welcome committed young people who want to learn more about the treatment of wastewater. You can also complete internships with us. Contact us so that we can support you in the best possible way.
