Internship: Nitrogen recovery

Internship: Nitrogen recovery

Future-proof water treatment: develop next-generation nitrogen recovery technologies

Currently, nitrification-denitrification is the most common technique for the removal of nitrogen from municipal wastewater. In the future, municipal wastewater plants should become energy and carbon neutral. It is hardly possible to achieve these requirements with the nitrification-denitrification process in combination with more stringent discharge limits. Therefore, different treatment technologies are required. With ion-exchange the more stringent discharge limits can easily be reached. However, ion-exchange produces a concentrated brine, which should be treated and partially reused.

Your goal

The goal of this internship project is to optimize a process which separates the ion-exchange brine into a valuable nitrogen fertilizer, as well as a clean brine suitable for reuse in the process.

What will you be doing? We have listed it for you:

During this internship you will investigate nitrogen recovery by

• Performing lab experiments
• Performing theoretical calculations
• Investigating the optimal nitrogen recovery using the theoretical calculations and the results of the experiments.

Internship available from January 2025 onwards. 

Who are you?

• Enrolled in a BSc or MSc Chemical, (Bio)Process, Civil or Environmental Engineering.
• Flexibility and indepence.
• Curious and analytical.
• Professional command of the English language in words and writing. Command of the Dutch language is desirable, but not required.
• Minimum 4 months internship.

Working for us means

• An internship allowance of €350,- per month based on full-time employment.
• Possibility of a contract after your graduation.
• A buddy who will show you around in our organization.
• Reimbursement of travel expenses of €0.23 cents per km up to a maximum of 75 km if you live further than 10 km from our office and do not have an Ov-card.
• Learn from knowledgeable and dedicated people.
• Create impact and contribute to critical water challenges.
• Become part of an inclusive and collaborative culture.
• Contribute to sustainability.

As an intern from the Technology & Innovation department, you will take on challenging and important projects along with Process Design Engineers and R&D engineers. You will run a project with your supervisor and a larger team located in Doetinchem and/or other locations (if applicable).
