Ion exchange is an exchange process between two electrolytes. It can be a process of purification, separation and decontamination of aqueous solutions. For this process, mainly ion exchange resins or zeolites are used, which are primarily positively or negatively charged.

Due to requirement of further reducing nitrogen discharge from wastewater treatment plants, new processes are being developed that minimize the formation of N₂O. Suspended Ion Exchange (SIX®) is a process that was developed and tested aiming at DOC removal from surface water. Lately, this process is being investigated for ammonium (NH₄⁺) removal, as an alternative to the conventional nitrification-denitrification process. However, more research is required to identify the feasibility of the process for ammonium removal.

Your goal

The objective is to investigate the NH₄⁺ removal in a SIX® system and optimize its performance.

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

• Conduct laboratory experiments at different operational settings and configurations.
• Perform data analysis of the experimental results.

Who are you?

• Enrolled in a Dutch BSc or MSc Chemical, (Bio)Process 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.
