Decanter is a device, which employs a high rotational speed to separate components of different densities it's a typical horizontal centrifuge. It is a sedimentation centrifuge for separation of suspended solids from one or two liquids. Decanters are used in wide wide range of application where the ability of achieve both good clarity and low moisture in the discharge solid is appreciated. They are very versatile as they can handle both large and small particles as well as a wide variety oif solids concentration and therefore play an important role in wastewater treatment, chemical, oil and food processing industries.
Decanter has a conical bowl and internal rotating scroll conveyor to propel solids or bleach them along the inclined wall to then be discharged.
Solids and liquids are discharged continuously in decanter. Decanter cab process coarse particle that would blind the discharge system and disc of bowl centrifuge.
In simple words decanter has a high capacity but efficiency is less when compared to disk stack centrifuge (Separator)
