Applications
The solids-ejecting centrifuge BTPX710SGD-34CDP disc separator with self-cleaning bowl in clarifier execution. It is equipped with a double axial spindle seal and timer-triggered solids discharge. It is used for removing suspended solids with particle sizes from approximately 0.5 to 500 μm from a liquid having a lower specific gravity than the solids. The solids content in the feed is normally in the range of 0.1-10 % by volume.
The main applications are bacteria, rDNA products, enzymes, growth factors, cell cultures and vaccines.

4) valid for water at throughput capacity 5 m3/h.
Operating principles
The feed is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe, and is accelerated in a distributor before entering the disc stack. Lt is between the discs that the separation takes place. The liquid phase moves towards the centre of the bowl, from where it is pumped out under pressure by means of a built-in paring disc. The heavier solids phase is collected at the bowl periphery, from where it is discharged intermittently via the centrifuge cyclone. The solids discharge is achieved by a hydraulic system below the separation space in the bowl, which at certain intervals forces the sliding bowl bottom to drop down, thus opening the solids ports at the bowl periphery. The bowl is mounted on a vertical spindle driven by a horizontally mounted motor via a worm gear in the BTPX710SGD-34CDP disc separator.
