Decanter Centrifuge

Elgin’s decanter centrifuge is the ideal solution for liquid/solids separation and dewatering operations. Whether you are working towards maximizing product recovery or looking to get the most out of your “zero-discharge” closed-loop system, Elgin has the turn-key solution for your operations.  Elgin has installed over 600 centrifuges worldwide and are a field proven solution.

A decanter centrifuge (also known as solid bowl centrifuge) separates continuously solid materials from liquids in various types of slurry material.  Used to separate a mixture that consists of two substances with different densities by using the centrifugal force resulting from continuous rotation. It is normally used to separate solid-liquid, liquid-liquid, and solid-solid mixtures.

As the slurry is passed through a rapidly rotating bowl, centrifugal force moves the heavier particles to the bowl wall, where they are scraped toward the underflow (heavy slurry) discharge ports by a concentric auger, also called a scroll or conveyor. The separation of the heavier particles divides the processed fluid into two streams: the heavy phase, also called the underflow or cake; and the lighter phase, which is called the overflow, light slurry, effluent, or centrate.

Centrifuge applications include industrial wastewater, horizontal directional drilling, geothermal, oil & gas, and microtunneling operations to name a few.
