## A state-of-the-art laboratory

Our laboratory combines **expertise** and **innovative equipment** for comprehensive wastewater treatment monitoring. In addition to standard analyses of process parameters - which allow us to control the quality of wastewater entering treatment plants, assess the performance of installed treatment units, and monitor effluent quality at discharge - our laboratory has a wide range of **state-of-the-art pilot installations**:

- Physicochemical treatment systems
- Biological treatment units (aerobic, anaerobic): with various configurations (MBBR, UASB, EGSB, etc.)
- Membrane filtration (MF/UF/RO) and primary or tertiary treatment systems (sand filtration, activated carbon filtration)
- Ozone (O3) oxidation tests, Fenton, etc.
- Electrolysis (ED) treatment units
- etc.
