PURPOSE: An apparatus for separating, washing, and collecting filtering sand is provided to efficiently recycle filtering sand and the contaminated water is purified and treated to reduce effluents. CONSTITUTION: An apparatus for separating, washing, and collecting filtering sand includes a drawing unit(200), a screw unit, a filtering unit, a separating unit(500), and a collecting bag housing(700). The drawing unit draws filtering sand from a filtering sand tank(100) with water and supplies the filtering sand. The screw unit introduces the filtering sand and water from the drawing unit and rotates to transport the filtering sand. The filtering unit surrounds the screw unit. The filtering sand separation holes are formed at the filtering unit. Separated sand reservoirs(520) are present in the separating unit. Separated filtering sand is divided in each reservoir by particle sizes. A filtering sand collecting bag(720) is installed at the collecting bag housing.
