Overview
The Alfa Laval BTPX-205 is a self-cleaning centrifuge of the disc-stack type. Its design allows it to separate the liquid from liquid and solids (purifier) or liquid from solids (clarifier).
The BTPX-205 features a 'partial solids' ejection feature that allows the centrifuge to purge only the solids. This feature reduces fluid losses associated with sludge ejection.
The sludge ejection cycle can be timer-triggered or based on the volume processed.
The centrifuge separates suspended solids such as organic cells in a broth or fine chemicals as a clarifier. When set up as a purifier, it separates solids and intermixed and immiscible liquid phases.
The solids content in the process fluid can be up to 10% by volume.

Applications
The BTPX-205 is applicable for removing suspended solids with a particle size of 0.5 t0 500 µm. The liquid centrate has a lower density than the solids.
The solids content is usually in the range of 0,1 to 10% by volume. The total solids content can be from 0.1% to 10% by volume.
The following are some of the popular applications of the Alfa Laval BTPX-205:
- Biotechnology
- Organic Cell Harvesting
- Cell Growth
- Clarification Fermentation Broth
- Clarification of Cell Debris
- Recovery of Inclusion Body
- Pharmaceutical
- Plasma Fraction Recovery
- Precipitate Recovery
- Vaccines and Serums Production
- Chemical
- Catalyst Separation
- Sub-micron Particle Separation
- Pigments, Dyes and Toners
The maximum process capacity of the machine is 5 Gallon/Minute.
Operation
The bio-culture fluid enters the rotating bowl of the BTPX 205 centrifuge. The bowl exerts a high g-force (12,800 Gs) on the process fluid.
The centrifugal force causes rapid sedimentation of the cells. These separated cells are auto-ejected from the centrifuge.
The liquid phase (broth) moves towards the centers and exits the bowl through a separate outlet.
A detailed explanation of the operation of the BTPX-205 centrifuge follows.
The process fluid enters the rotating bowl of the centrifuge through a stationary inlet pipe (1). The distributor (2) accelerates the fluid before it enters the disc stack (3).
The separation of the solids from the liquid happens in the inter-disc space.
The clear liquid moves towards the center of the bowl. A paring disc (4) pumps out the clear centrate.
The denser solids move towards the bowl periphery. From there, their ejection happens through the centrifuge cyclone.
A hydraulic mechanism located under the bowl separation space causes the sludge ejection. This mechanism forces the sliding piston (5) downward, opening the solids ejection ports (6) at the bowl periphery.
The cyclone reduces the high ejection velocity of the solids.
