Abstract
A long sand trap for separating and removing sand from inflow channels, particularly of sewage treatment plants is provided with a settling channel (1) having in particular a trapezoidal cross-section and extending along a straight path. A transporting conveyor device (8) which is acting opposite to the direction of flow is provided in the bottom area (6). A classifying conveyor device (10) discharges the sand delivered from the transporting conveyor device (8) in an upwardly inclined manner. The classifying conveyor device (10) is arranged in the central longitudinal plane (3) of the settling channel (1). It has a discharge chute (17) which can be used selectively left-hand or right-hand.
