This concept perfectly applied to an oil skimmer. The oil skimmer can act without much supervision and can remove the oil that builds up in the oil separator. The removed oil would then be discharged into a provided IBC.
To test whether skimming the floating phase with an oil skimmer using an oil collector tube is possible, and whether it provides the desired results, an oil skimmer model 1S mounted on a frame was used on the oil separator. The oil skimmer operated continuously, removing oil and grease that had entered the wastewater stream.
After a short period of time, it was clear that the oil skimmer was removing considerable amounts of oil and grease. This was shown by the steadily rising level of oil in the IBC. Occurrences of exceeding contamination limits at the downstream gauging station also decreased.
