In modern industry, the purpose of solid-liquid system (including suspensions and emulsions) separation is: recovering valuable solid phase and discharging liquid phase; recovering the liquid phase and discharging the solid phase; recovering both solid phase and liquid phase; both the solid and liquid phases are discharged (e.g., sludge dewatering). The main operating methods to achieve solid-liquid separation consist of gravity settling, filtration and centrifugation. The method of achieving solid-liquid separation by centrifugal force is collectively called centrifugal separation. The machine that performs the centrifugal separation operation becomes a centrifuge.
