Drinking water storages play a central role in ensuring a safe water supply. Stagnant water can lead to algae formation, post-germination or concentrations of chemical substances which are hazardous to health. INVENT HYPERMIX is a fluid-mechanically optimised agitator which homogenises water efficiently. It breaks up stratification and continuously mixes the contents of the basin. The vortex ring prevents spiral vortices, thus maximising the efficiency of the machine. A quick installation which does not require any special tools was also taken into consideration during the development process.
