Abstract
A device for preventing sedimentation by regulating the flow of waste water through drain draining-wells, with or without a pump. The device has of a swirl chamber with connected outlet pipe and provided with an air injector. The swirl chamber which is tapered, generates a vortex flow in which the air added by the air injector gives the sludge particles a certain amount of buoyancy, making it easier for them to accompany the water flow without being precipitated.
