A centrifuge decanter; consists of a solid cylindirical bowl rotating at high speed, a scroll rotating at the same axis with a slightly different speed, a drive group adjusting the speed difference and the body which carries all the rotating elements.

Liquid and suspended solids are fed along the centre line to a distribution room within the bowl and then accelerated into the bowl by centrifugal force through the feeding point. This centrifugal force then causes the suspended solids to settle and accumulate at the bowl wall.

Sludge cake is discharged by scroll from the conical part meanwhile clarified liquid flows back along the bowl and is discharged through the cylindirical end of the bowl by plates which can adjust the level of clarified liquid.

Centrifuge decanters are applied for separation of liquid mixtures, separation of solid-liquid mixtures, dewatering, thickening, classification of solid-liquid mixtures and extraction of components.

Constant Speed Drive System
This system has low investment costs due to very simple design. This drive system is used when the solids amount is constant, the solids can be conveyed easily and the amount of moisture in the solids is not critical, which means it is not necessary to adjust the differential speed.
Dual Drive System
Dual Drive provides differential speed to be adjusted in a wide range. Second motor drives the gearbox input shaft and makes the differential speed as a function of bowl speed and gearbox rate. Required speed is adjusted when the solids amount is variable noticeably, it is hard to convey the solids and it is important to minimize the amount of water hold in the solids without any human interference. Differential speed is adjusted automatically and very precisely as a function of scroll torque. The system is supported by the software developed by HAUS.
Semi – Driver System with Hydraulic Motor
Instead of a mechanical gear, a rotating hydraulic drive is assembled and this motor is supported with hydraulic regulation. Automatic regulation can be done with no problem because the differential speed is directly proportional with the amount of the oil transmitted. Driver system with hydraulic motor is used when the solids amount is variable, it is hard to convey the solids and it is important to minimize the amount of water left in the solids.

2-Phase Decanter

This technology is developed for applications requiring solid-liquid separation. Separating two liquids in a single equipment has simplified many processes.

3-Phase Decanter

This technology is developed for applications requiring solid-liquid-liquid separation.
