Aeration tank at a refinery


The installation of 12 six-path ejectors was completed during the course of converting the waste water treatment plant of the Rheinland Raffinerie Godorf Works belonging to Shell Deutschland Oil GmbH to an intermittent gassing with pure oxygen. Respectively 3 ejectors each are connected with a pipeline and fed mutually from a submersible motor-driven pump. The pump is mounted on the pipeline by means of an underwater coupling and can be retrieved any time via guide tubes.
