Abstract
Pollution removal is carried out using particles of felt made of hydrophobic mineral fibers, in which the felts used, which have been preliminarily compressed for storage and transport and after an unbinding operation, undergo pneumatic transport sufficiently forceful to allow them to regain their original density, said pneumatic transport being used simultaneously to spread the particles on the surface of the water to be treated.
