Wastewater Treatment Laboratory

Keeping your wastewater treatment plant running smoothly and meeting discharge standards? From a microscopy on sludge to ecotoxicity tests, from (standard) analyses to a pilot test. Your conceptual studies are validated by our laboratory in the region of Ghent. This way, we can guarantee reliable, sustainable solutions.
(Ecotoxicity) Tests, Analyses & Pilot Studies

Our lab for wastewater treatment: 
more than just a lab for analyses

To meet discharge standards or to keep your treatment plants functioning optimally, you need reliable data. With the results of the right test or analysis, you can easily fine-tune your water treatment.

We offer fast and accurate results, support you in interpreting the data and guide you to a suitable follow-up of your WWTP.

This allows you to consciously choose solutions that are good for your company technically and economically and environmentally friendly.


Tests and analyses on (waste)water
