The centrifugal force that is generated is capable of separating particulate solids down to around 5 to 10 microns in sie. The smaller the diameter of the cyclone the higher the force and the higher the efficiency of separation of small particles. Long cone designs also exist which claim to give good efficiency with particles of less than 5 microns

Masstransfer measurement. The volumetric masstransfer coefficient is determined by the desorption of dissolved oxygen from water using nitrogen as the gas phase. Calibration of the oxygen probe is achieved at a room temperature of 301 K and an ambient pressure of 1.013 215 10 5 Pa. The oxygen concentration at the inlet is usually 7.98 mgL
