What are full retention separators?
Full retention separators are used where there is a risk of regular oil contamination and a foreseeable risk of significant over spills. They are designed to treat the full flow that can be delivered by a drainage system. This is normally generated by rainfall intensity of 65mm per hour, often referred to as ‘torrential’.
- sites with high risk of oil contamination
- fuel storage depots
- refuelling facilities
- vehicle maintenance areas/workshops
- where discharge is to a sensitive environment
How do full retention separators work?
Contaminated water enters the separator where the liquid is retained for a sufficient period to ensure that the pollutants (such as petrol, diesel or oil) separate and rise to the surface of the water.
The decontaminated water then passes though the coalescing filter before it is safely discharged from the separator, with the remaining pollutants being retained inside the separator.
Retained pollutants must be emptied from the separator once the level of oil is reached, or the oil level alarm is activated. This waste should be removed from the separator under the terms of the Waste Management Code of Practice.
All Rewatec full retention separators have an automatic closure device (ACD) fitted as standard. This is compulsory for all compliant full retention separators and prevents accumulated pollutants flowing through the unit when the maximum storage level is reached.
