Separating solids from liquids plays a key role in countless industrial processes. Traditionally, many businesses use a clarifier or settling tank, in which particles, sediment and solids gradually fall to the bottom due to the force of gravity. However, such clarification is an extremely slow process with not so controllable results.
To accelerating the process, decanter centrifuge operation makes use of centrifugal force – the effect can be up to 4000 times greater compared to using gravitational forces. Solid-liquid separation can also be easily controlled by adjusting the speed of rotation..
What happens during solid-liquid separation using our decanter centrifuge? Subject to centrifugal forces, the denser solid particles are pressed outwards against a rotating bowl wall, while the less dense liquid phase forms a concentric inner layer in a decanter centrifuge. Different dam plates are used to vary the depth of the liquid – the so-called pond – as required. The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually “ploughed” out of the pond and up the conical “beach”.
The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl. Baffles within the centrifuge casing direct the separated phases into the correct flow path and prevent any risk of cross-contamination.
The speed of the screw conveyor may be automatically adjusted by use of the variable frequency drive (VFD) in order to adjust to variation in the solids load.
