Your visitors trust that they will stay healthy and safe while swimming. But how can you guarantee that the water will stay clear and that it is treated appropriately without countless side effects? This requires ample technical knowledge and expertise on site, such as employees who can properly measure pool water quality and accurately interpret monitoring results. With a view to the new rules for pool water, this knowledge and these skills have become indispensable.

Scientist and Hellebrekers employee Maarten Keuten noticed clear room for improvement in pool water monitoring skills in Dutch swimming pools. He decided to do something about it: based on Maarten’s theoretical knowledge and practical experience at Hellebrekers he developed the Pool water filtration and Pool water chemistry masterclasses. We organise these masterclasses several times a year, and they are part of the licensing scheme of the National Swimming Safety Council. They have proven to be very instructive for participants, providing extremely valuable insights that can be used in daily practice.
