SOLID BOWL CENTRIFUGE TECHNOLOGY

Modern centrifuges are used in technical processes for the mechanical separation of mixtures of solids and liquids. Sedimentation and filtration are mechanical separation processes, in contrast to distillation, incineration and thermal drying, which are thermal separation processes. In many processes, the mechanical separation has a decisive influence on product quality, production efficiency and environmental impacts. Mechanical separation processes are found in practically all industrial sectors, including but not limited to food, chemical, pharmaceutical, biotech, mineral, and environmental processing.

Advantages of modern centrifuges

Modern centrifuges have many advantages in comparison to other separation processes such as filtration and static settling:
• Compact designs
• Sealed construction to control odor emissions and avoid contamination of the product
• Ease of operation with continuous or automatic control systems
• Limited consumables such as filter media or filter aids

BASIC PROCESS OPERATIONS

To obtain optimum results, solid bowl decanter centrifuges must be custom designed to suit specific separation processes.
Flottweg meets the needs of the vast range of applications by offering a variety of basic designs, such as the decanter, Tricanter®, Sedicanter® and Sorticanter®. Solid bowl centrifuges are used in most areas of mechanical liquid-solid separation.

The following basic process operations are possible using solid bowl decanter centrifuges:

• Clarification of liquids
• Dewatering of sludges and suspensions
• Thickening of sludges
• Separation of three-phase mixtures, i.e. two immiscible liquid phases and a solid phase
• Classification of solids in a suspension according to particle size (wet classification)
• Sorting of solids by density
