Compact-modular water treatment is an effort to fulfill water demands to areas that do not get clean water. Compact-modular water treatment earlier been operated and has researched good efficiency. But there is a disadvantage that a filter clogging caused by the load on the previous processing (sedimentation) units are less efficient (Mahyaningsih, 2013). In this study, sedimentation units earlier using upflow on the PVC tube and use the addition bioball will be replaced by units with horizontal flow sedimentation using a turned incline plate settler. However, to get the ideal conditions and is suitable to be applied in the field, laboratory-scale experiments required in advance and hydrodynamic factors in order to assess the application in the field has been as expected. Therefore, the present study focused on hydrodynamic simulations using CFD to obtain the optimum design and testing in the <br /> <br /> laboratory with create a lab-scale reactor sedimentation units are designed with a flowrate of 1.5 L/min to test the design which has been designed. In addition, the present study aimed to determine the effect of turned are applied to the sedimented floc and efficiency. Obtained from simulations, turned incline plate settler more efficient because it can minimize the deadend <br /> <br /> zone that occurs when compared to the inclined plate settler. The simulation results showed that the hydrodynamic simulated by CFD software has been nearly resembles with the experiment so that the model can be used to the flow contained in the sedimentation unit. <br /> <br /> Performance installation with turned incline plate settlers result in better efficiency with allowance for TSS between 92.839% -94.609%. As for the inclined plate settler produce TSS removal efficiency between 86.441% -91.278%. So, the effects of turned incline plate settler to the sedimentation unit efficiency/performances are exists, it causing the flow changes direction and then the particles has the chances to colliding each other, then the floc sedimented and treated water on this sedimentation unit are better than the ordinary sedimentation unit.
