New methods for removing algae from drinking water
How to remove algae from drinking water? Since traditional methods, such as coagulation and sedimentation, are usually ineffective, Prof. Dr. Matevž Dular from the Laboratory for Water and Turbine Machines (LVTS) at the Faculty of Mechanical Engineering, together with colleagues from Yangzhou University, sought a solution in the use of ultrasound and advanced carbon-based materials.

Using cavitation to break down invisible water pollutants
Researchers from the Faculty of Mechanical Engineering and the National Institute of Chemistry conducted an experimental study in which they achieved the degradation of a water-soluble synthetic polymer - poly(vinyl alcohol) PVOH - by acoustic and hydrodynamic cavitation. The use of PVOH is rapidly increasing, and as a result, increasing amounts of this material are being released into the environment. PVOH is widely used in the textile and paper industries, as well as in households, for example in the form of detergent pods. It is estimated that thousands of tons of it are washed into the aquatic ecosystem every year.
