Internship: Optimization of the Ceramic Microfiltration Process for Surface Water Treatment
Join PWNT’s R&D team and help optimize ceramic microfiltration for cleaner drinking water. Hands-on lab work, data analysis, and innovation in sustainable water treatment.

PWNT, part of Nijhuis Saur Industries (NSI), offers an exciting internship position within the Research & Development team. During this internship, you will contribute to optimizing the ceramic microfiltration process for surface water treatment, with a special focus on improving pre-treatment operations.
With pioneering technologies such as ion exchange, ceramic membranes, and advanced oxidation, we develop sustainable water treatment solutions that are applied worldwide.
About the Internship
Ceramic microfiltration is one of PWNT’s key technologies for the production of high-quality drinking water. Pre-treatment plays a crucial role in ensuring the efficiency and reliability of the filtration step.
During your internship, you will investigate how different pre-treatment conditions influence the performance of ceramic membranes. You will design and monitor laboratory experiments, analyze the data, and propose optimizations that can be applied at water treatment facilities worldwide
