Abstract (en)
[origin: WO8301799A1] A device for depolluting a water sheet comprises a hull having a central portion (10) protruding with respect to two side portions (11) which delimit with the central portion delivery pipes to separators. The central portion has a wing (17) for generating swirls of which the orientation reduces the divergence of the surface flow. Each pipe (16) has a floor with a drifting profile with a protruding leading edge for slowing down the flow and for thickening the polluting layer. A vertical partitioning wall separates each pipe (16) into two subchannels of which one communicates downstream with the separator and the other one opens, at the rear portion of the device, into a pump (53).
