TASC

The TASC type is conceived for the biological aeration treatment of sewages. It consists of an electric motor, a gearbox of optimum quality, selected among the best in commerce, a coupling, a shaft and a turbine. The electric motor, by means of the parallel and/or planetary gearbox, controls the shaft on which the turbine is keyed. It is provided with a number of blades variable from twenty to twenty-four, stiffly anchored according to a specific welding process. The connection is generally carried out by means of a bolted flange. The advantage of the TASC turbine consists in the high potential in recycling the sludge which is submitted to a diffused and homogeneous aeration of the whole mass.
It is also possible to request the TASCG type which equipment is fitted on a metal floating structure consisting of three cylindrical tanks and suitable support and centering elements. This type of turbine is particularly recommended for the aeration of lagoons or basins whose liquid level is variable.
The standard construction is in carbon steel. On request it is possible the use of stainless steel.

Strenghts

• OPTIMUM RATIO: OXYGEN TRANSFER RATE/INSTALLED POWER.
• HIGH SEWAGE RECYCLE CAPACITY.
• DIFFUSED OR HOMOGENEOUS AERATION ON THE WHOLE TANK MASS.
• OPERATION WITHOUT ANY VIBRATIONS THANKS TO THE BLADE ARRANGEMENT.
• POSSIBILITY OF INSTALLATION ON VARIABLE-LEVEL BASINS (TASCG).
