Electric agitator with submerged turbine for denitrification

The electric agitator with submerged turbine ETSD type is installed in civil or industrial water treatment, mainly for the denitrification or soft mixing. It consists of an electric motor, a gearbox, a lantern, a shaft and a turbine impeller. The impeller is made of steel metal sheet adequately shaped according to the treatment to be carried out. It is complete with blade, generally six, connected by bolted or welded unions. With regard to the shafts with a length exceeding five meters, the impeller is driven and supported at the base by a self-lubricating support. The electric agitator ensures the continuous maintenance in suspension of the biomass or other materials, keeping the whole liquid mass in motion and avoiding any whirls or little turbulences. On request, it is possible to install a variable speed drive (ETSDV) in order to optimize the rotation speed. The standard construction is in carbon steel. On request it is possible the construction in stainless steel or with particular protections.
