Homogenisation in 1000 m3 Tank with 80 g/l Solid Concentration
This plant is aimed at the production of biogas from civil organic waste. The plant consists of 3 basins for collection and homogenisation of aerobic digested sludge with 30 to 80 g/l. The tank volume is about 1000 m3, dimension 12 x 10 x 9.4 m (W x L x H), liquid level 8.4 m.
PRO-DO-MIX installed 3 mixers, model GPL.A5350.Q.800.
Due to the high liquid level inside the tank we decided to equip the mixer with a 3PM-0030 high efficiency impeller, diameter 3500 mm, in order to keep the tank bottom clean and to push the sludge upwards, with an high recycle rate but only 10 w/m3 power consumption.
The drive unit is composed of a 15 kW motor and an industrial bevel gearbox, able to support the thrusts of the impeller 8 m distant from the mounting flange.
Due to the agitator’s shaft length, we have adopted a special mechanical construction dividing the shaft into 2 pieces to ease transport and installation operations.
