Features a hyperbolic impeller positioned near the bottom of the tank/lagoon, which, through its rotating motion, imposes a downward flow on the liquid from the surface to the bottom with complete mixing, without “dead zones,” ensuring homogeneous and efficient mixing at all liquid levels. It can be installed on a fixed tower-type structure resting on the bottom of the tank/lagoon, on a walkway supported on its edges, or with a floating structure.
