<p>A process and an installation for capturing and recovering polluting substances that generally float on the water surface, in particular petrol products, are described. A plurality of foraminous, floating recipients (12) in gondola form that are connected together by a cable or a chain (11) and contain a solid absorbent (17), preferably a phenolic foam having a low density and a high absorbtion speed and capacity, are pulled in a closed loop over the polluted water and then hauled on board of a boat which holds the driving means for said cable. The gondolas are emptied on board the boat, filled with fresh absorbent, and then released again into the water. The recovered foam is compressed and then stored on board as well as the pollutant expressed from the foam. Preferably, the unit for manufacturing the absorbent foam is also installed on board.</p> |
