centrifugal clarification, a process that runs in hydrocyclones and sedimentation centrifuges. Centrifugal clarification is highly effective as it speeds up the sedimentation of impurities by a factor of 3 to 30 [2]. Hydrocyclones are different from centrifuges or centrifugal separators in the sense that they lack moving or rotary parts.
