Waste Water mixer

Submersible Mixers

are used in waste water treatment, namely in nitrification, denitrification, activated sludge treatment and disinfection tanks. These mixers are also applied in industrial mixing, chlorination tanks and digesters of biogas plants used to homogenize, destratify and prevent formation of surface hardpans.

The slow rotation of blades, obtained by application of a reduction gear, makes flowmakers ideal to mix and recirculate, produce currents and distribute efficiently the oxygen provided by aeration system
