WWS Wasserkraft - Rake Systems and Trash Rake Cleaning Machines

The fine rake field is installed in front of the turbine inlet or the inlet to the penstock in order to filter floating debris. This trash rake field can be made from simple flat steel, however, WWS relies on flow-optimized profiles to reduce losses.

The trash rake cleaning system is responsible for cleaning the trash rake fields from the accumulated debris (branches, leaves, garbage, etc.). The debris from the vertical rake cleaning system is transported into the flushing channel where it is removed with the help of the flushing pump.

At the horizontal trash rake cleaning system, the floating material is laterally fed back into the underwater. As a result, the microorganisms remain in the river and the ecological balance is maintained.
