Horizontal Bowl centrifuges are also known as decanters and are primarily used for separation of liquids from appreciable amounts of solids. Decanters can separate over 50% (v/v) solids from liquids on a continuous basis. Typical applications includecleaning of tank bottoms, waste oil cleaning, waste water treatment, sludge dewatering in industries etc.

Working principle :::

A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity. When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer. Different dam plates are used to vary the depth of the liquid – the so-called pond – as required.
