Where is water directed after being processed in the OWS?

Water processed in an Oily Water Separator (OWS) is specifically designed to remove oil and other contaminants from bilge water before it is discharged into the sea. The primary function of the OWS is to ensure that the water meets environmental regulations regarding oil content, typically allowing for a discharge that contains a very low concentration of oil. When the processed water is deemed to be clean enough, it is directed overboard, which means it is discharged into the ocean or adjacent water body. This process helps in maintaining compliance with international maritime pollution regulations and protects marine environments.

Other options refer to potential alternative disposal methods but do not reflect the intended operation of an OWS. A holding tank or a wastewater treatment facility would imply a further treatment process rather than direct disposal, while a filtration system suggests additional processing before discharge, which is not the primary function of an OWS.
