Oil and fuel collector

Abstract

There is disclosed a collector for machine fluids, comprising a mat having a perimeter wall upstanding therefrom, the mat and/or the wall comprising oleophilic material and the wall being water-permeable, so that water falling into the collector within the perimeter wall can escape therefrom, while the machine fluids are retained by said oleophilic material and wherein the collector comprises at least one composite component for machine fluid retention comprising at least three layers wherein at least one layer comprises activated carbon and wherein this layer is secured within the composite between two layers of porous material mechanically bonded to each other, preferably via needle punching, through the activated carbon layer. The collector has high efficiency in removing PAHs and other aromatics from oil/fuel contaminated water.
