The need of fresh waters in Indonesia particularly in urban area is dramatically increasing without accompanied by the supports of water resources. Therefore, water treatment facilities are needed to fulfill the prerequisites of fresh waters. This process generally separates solid/ sediment parts from water prior to biological and chemical treatments. Water treatments in light of separating solids and liquids which in its process using filters need regular maintenances and renewal of filter parts in case of its functions are beginning to decease. The purpose of this study is to developed a model of the sediment particle motions in rotating fluids and comparing with the laboratory experiments. The Research shown that, it\'s expected to identify the rate of solid/ sediment settling in rotating flows. Rotating flows with centripetal force was considered in order to separate solid and liquid, and done in a circular tube with rotating fluids. In this study, it was tried to prove that the prevailing centripetal force on sediment particle generally accelerated the settling of cohesive sediments when parts of sediment particles reached the edge of the tube leading to the accumulation of body force which in turn lead the sediments to deposit. This physical separation made water in the upper part of tube was clearer; therefore water sampling in this point can be continued to another treatment. <br /> <br />
