The invention relates to a separation device for removing objects from a water flow, comprising a separation screen and a channel which forms an inlet and an outlet for the separation screen, wherein, during operation, a head water having a head water level can be provided in the inlet upstream of the separation screen and a tail water having a tail water level can be provided in the outlet downstream of the separation screen, wherein the outlet comprises an outlet cross-section for the water flow. The separation device is characterised by a damming body, which can be adjusted via an actuator, for immersion into the outlet, said damming body being able to be adjusted at least between a first position and a second position, wherein the outlet cross-section is smaller in the first position and the outlet cross-section is larger in the second position, and comprising a control device, wherein the control device includes a first operating mode, in which the flow rate in the area of the separation screen is increased by bringing the damming body from the first position to the second position, wherein the control device includes a second operating mode, in which the flow rate in the area of the separation screen is changed by bringing the damming body from the second position to a third position, wherein the outlet cross-section in the third position is smaller or larger than in the second position, and wherein the control device is configured to automatically activate the first and/or the second operating mode. The invention also relates to a method for operating such a separation device.
A separation device for removing objects from a water flow having a flow velocity, comprising a separation screen and an open channel which forms an inlet and an outlet for the separation screen, wherein, during operation, an upstream water level can be provided in the inlet upstream of the separation screen and a downstream water level can be provided in the outlet downstream of the separation screen, wherein the outlet comprises an outlet cross-section for the water flow, a damming body, which can be adjusted via an actuator, for immersion into the outlet, the damming body adjustable at least between a first position and a second position, wherein the outlet cross-section is smaller in the first position and the outlet cross-section is larger in the second position, a first sensor configured to detect a first characteristic of the water flow in the open channel, and a control device in communication with the first sensor, wherein the control device has a first operating mode in which the flow velocity of the water flow in an area of the separation screen is increased by bringing the damming body from the first position to the second position and a second operating mode in which the flow velocity of the water flow in the area of the separation screen is changed by bringing the damming body from the second position to a third position, wherein the outlet cross-section in the third position is smaller or larger than the outlet cross-section in the second position, and wherein the control device is configured to automatically activate the first and/or the second operating mode based upon a first sensor signal sent to the control device by the first sensor wherein the first sensor signal relates to the first characteristic of the water flow.
