A space is formed between the walls of the device and bottom of the tank. The device includes a filtering belt (12) arranged on the bottom of the tank for filtering the liquid contained in the tank before reaching the evacuation cavity. The belt is permeable to water, and includes a retaining unit for retaining hydrocarbons in the liquid. |
