VacaturesInternship: Sustainable Solutions for Process Water Treatment & Reuse

DoetinchemHBOWOStage32-40 uur



In industrial and commercial sites there are multiple water qualities and flows present to enable diverse processes. One example is the use of cooling water to dispose of large amounts of heat that is being generated in production processes and utilities. The cooling water is picking up heat in the condenser and is cooled in a cooling tower by evaporation through intense air-water contact. The water is recirculated as much as possible to maximize water savings and at the same time the water chemistry is changing.

Treating the water from cooling towers requires in-depth knowledge and understanding of the entire process to avoid a water environment that leads to corrosion, scaling or biological activity.

Goal and activities

The goal of this internship or graduation project is to develop a calculation model (digital twin tool) for controlling and optimizing the water chemistry of the recirculation water. Actual data from cooling water will be used to verify the model. The candidate should have a background in water chemistry and interest in mathematical modelling. The developed model will be used in practise on daily basis on many existing installations and new process designs.\
