Learn non perforated basket centrifuge principle, working, construction, uses, advantages and disadvantages. This centrifuge doesn’t contain the porous medium.
What is Non perforated basket centrifuge?
This centrifuge follows sedimentation mechanism without the help of porous medium.
Centrifugation follows the order of different densities between the solid and liquid phases.
Non perforated basket centrifuge principle
This centrifuge doesn’t contain any porous medium. The bowl contains a non-perforated side wall. During centrifugation, liquid phase reach at top of the bowl and then collected. But the solid phase retains on the side of bowl.
At the last minute of operation liquid phase is removed by skimming tube.
Construction
- It consists of basket, which made of steel or other suitable materials.
- The basket is in vertical shaped, which is driven by a motor by using suitable power.
- A feed pipe is adjusted to the basket.
- A skimming tube is used to collect the liquid from the top of basket.
- Scraper or sharp materials is used to collect the solid cakes from the side of perforated wall.
Working
- Particles or suspension is introduced to basket by help of feed pipe.
- Start the motor by using suitable power system.
- Rotate the basket in maximum speed for specific period of time.
- Make sure the liquid phase float on the top of basket, while the solid phase retains on the wall of basket. Then stop the motor.
- Collect the liquid by using the skimming tube.
- And collect the solid phase by using a scrapper or blade by hand.
Uses
- Chemical industry: Separating solids and liquids.
- Pharmaceutical industry: Purifying active ingredients.
- Food and beverage industry: Clarifying beverages and separating solids.
- Wastewater treatment: Reducing sludge volume and material recovery.
- Mining industry: Dewatering and clarifying mineral mixtures.
- Biotechnology industry: Biomolecule separation and concentration.
Advantages of Non perforated basket centrifuge
- Increased solids recovery.
