E: End-of-pipe measures contribute to the elimination of substances from wastewater. Whether the the end-of-pipe-measures applied at the WWTP you release to are suitable for the eleminiation of a not readily biodegradable and at the same time mobile substance is examined at this point of the interactive scheme. From the multitude of possible processes in a WWTP the following measures are listed as examples. In the analyses it is irrelevant whether it is your own WWTP or a third-party facility.
Not exhaustive list:
• Does the substance form an emulsion? Could the emulsion be dissipated completely, e.g. by using a fat separator?
• Is the substance liquid and forms layers in waste water?
• Does the substance float due to density lower than water? Could the substance be removed from water surface by devices already installed?
• Could the substance be degassed from water, e.g. by changing temperature and/ or air pressure?
• Could the substance be precipitated or flocculated?
• Could the substance be removed from water with additional devices e.g. active charcoal filter?
