They are placed outside the channel in order to remove the sand in the inlet water from the system. Waste water entering the system from the inlet line of the “Sand Separator” flows into the clarifier part of the separator where the sedimentation process will take place. After the settling process, the cleaned water is discharged from the outlet line of the separator by sluice. Sand accumulated at the bottom, etc. materials are discharged from the top point of the separator with the auger system. “Sand Separators”; Thanks to its low screw rotation speed, it works with high efficiency for liquid-solid separation.
