A Full Retention Separator is a tank used in high-risk areas such as a car wash or scrapyard where the risk of pollution is high. They are designed to fully retain 100% of the surface water from the drained area resulting from an intensity of 50mm per hour for a period of time long enough for the water and hydrocarbons to separate.
Full Retention Separators are fitted with a closure device which prevents the flow passing through the separator when the retained oil exceeds storage volume.
We can supply Full Retention Separators ranging from 222m2 area drained to 1111m2 area drained.Larger sizes are available on application. Full Retention Separators are sized by the area drained.
