Sludge Thickner
Sludge thickener with central drive:
The sludge thickener with the central drive is installed on medium and large-size treatment plants if a substantial reduction of the percentage of water contained in the organic or inorganic sludge is desired. The thickener consists of a rotation unit with central drive, comprising an electric motor, a multistage reducing unit, baffle cylinder, shaft, and scraping system consisting, in its lower part, of a couple of blade holder arms and, in its higher part, of a set of pickets. The multistage reducing unit is planetary type.
The shaft is suspended in line with the unit. The sludge inlet is in the middle, but the flow is deviated by the baffle to optimize the thickening. The sludge scraper blades, made in standard section, remove the sludge accumulated on the bottom and collect it in a central pit wherefrom, by piping, is conveyed to the outlet.
Blades and pickets are adjustable. The protection against overloads is carried out by an adjustable torque limiting switch, complete with an alarm signal to be displayed on the control panel. The walkway can be made in concrete or metal structure.
The standard construction is in carbon steel. On request, the construction may be in stainless steel.
Sludge thickener with peripheral drive :
The sludge thickener with the peripheral drive is installed on medium and large-size treatment plants if a substantial reduction of the percentage of water contained in the organic or inorganic sludge is desired. This type of thickener consists of a mobile steel girder, a baffle cylinder, a scraping system with two blade holder arms in the the lower part and a set of pickets in the higher part, a double lateral trolley, and two rotation units with peripheral drive, each complete with an electric motor and a gearbox.

STRENGTHS :
- HIGH SLUDGE THICKENING THANKS TO AN ADEQUATE ROTATION SPEED. ADJUSTABLE BLADES AND PICKETS.
- MINIMUM ENERGY CONSUMPTION
