The liquids and solids, which are, will be, due to the different sediment velocities to be gained, separated and sediment in the centrifuge and gravity force fields thus to reach the purpose of separation. The liquid phase and solid phase, which interactive indissoluble and with different densities in the turbid liquid will be gained different sediment velocities, so as to be divided into layers, which can be separated from each other. The separations that occur in the gravity field are called gravity separation and sedimentation in the centrifuge field called centrifugal separation and sedimentation.
Gravity Separation When the turbid liquid is in the sediment pool, the solids with bigger density sediments slowly in the gravitational fields by the gravity, finely the turbid liquid will become clearer and clearer. The liquid with smaller density will float on the top. For gravitational separation, it will take long time and more floor space occupied, especially, for the of the liquid with solid and liquid small differ and big stickiness, gravitational separation of it is difficult to be realized.
Centrifuge Separation The indissoluble liquids and solids with different densities will be separated while they are rotated at a high speed in the bowl, where the particles with heavier density move to the inside wall of bowl body, the lighter liquid toward the center of the bowl. Because the centrifugal force generated in the centrifuge fields in much larger than the gravity force, it takes only very short time for the centrifuge separation to achieve the same separation efficiency in the gravity fields. Especially when the gravity separation cannot be available, the application of best method is by centrifuge separation.
