In order to control oil accidents and to prevent the oil film drifting on the water from spreading, an oil adsorber 1 is provided, in particular shaped as a barrier 2. This barrier 2 is designed in two parts. Both cells 9, 10 are completely filled with glass fiber material or with corresponding fiber mats 11, 12. The glass fibers 28, 30 of the top cell 9 are waterproofed, by an appropriate coating, whereas the fibers of the bottom cell 10 are not treated, so that they absorb water 6. In both cases epoxy resin or a synthetic resin having the same or similar properties are used, so that a long service life is achieved with optimum solidity and design possibilities. The oil adsorbers 1 thus obtained may be used both as barriers 2 and as flat suction elements, for example to clear bilge waters from ships 3. It is also conceivable to use the flat or funnel-shaped elements for collecting components of an aqueous solution, for example.
A barrier for containing spills comprising an elongated fiber strand having at least two portions forming first and second portions along a length of the strand, the first portion comprising plural hydrophobic mats and the second portion comprising plural hydrophilic mats.
A containment barrier comprising first and second sections running adjacently along longitudinal axes of the sections to form the barrier, the first section comprising plural cells forming storage cells, the second section comprising a wedge-shaped cell forming a guide cell, and the barrier further comprising spaces between the plural cells, and at least one tow cable provided in a space between the cells.
