Applications
The MBPX404 separation system is based on the solids ejecting disc separator Disc Separator MBPX404SGP-31C in clarifier execution with fixed partial discharge mechanism for timer triggered discharge of solids. It is used to remove suspended solids with particle sizes of approximately 0.5 to 500 μm from a liquid having lower specific gravity than the solids. The solids content is normally in the range of 0.1-10% by volume. The main applications are bacteria, rDNA products, enzymes, cell cultures and vaccines.
The MBPX404SGP-31C is best suited for small scale fermenters ranging from 50 to 500 liters, and where in situ steam sterilization is not mandatory. Thanks to its compact size and mobility, the module is ideally suited for development applications. The Disc Separator MBPX404SGP-31C offers reliable scale-up possibility for production facility.
Operating principles
The feed is introduced to the rotating centrifuge bowl of Disc Separator MBPX404SGP-31C from the top via a stationary inlet pipe, and is accelerated by the disc inlet in a distributor before entering the disc stack. Separation of solids particles takes place in between the conical discs. 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 type centripetal pump. The heavier solids phase is collected at the bowl periphery from where it is discharged intermittently in the sediment space and decelerated in the cyclone of Disc Separator MBPX404SGP-31C. 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 vertically mounted motor, via a belt drive.
