Description

FLOATING BARRIER FOR WATER POLLUTANTS The present invention relates to a floating barrier for arresting, confining and absorbing mineral oils, acids and other liquids suspended in water and having a specific gravity less than that of the water.

The serious damage caused by the pollution of bodies of water is very well known, particularl the damage caused by the continuous discharge into bodies of sea water from tankers of acidic substances, oily products and similar polluting fluids* These pollutants, floating on the surface of the water because of. their lower specific gravity, progressively diffuse on the water to reach, ultimately, harbors, shorelines and beaches.

Therefore, numerous attempts have been made to arrest these polluting substances from damaging water basins, but no proposed solution has solved the threatening problem.

It is the main object of the present invention to provide a floating barrier for arresting, confining and absorbing the above-mentioned pollutants. j|hls barrier is highly resistant to the corroding effect of such substances as sea water, mineral oils, acids, and the like.

It is another object of. the invention to provide a floating barrier entirely constructed of synthetic plastic material, capable of floating on the water without additional supplementary floating or anchoring means.

A further object of the present invention is to provide a barrier of the type mentioned above, which is capable of resisting the impa'cjj of the waves without physical damage to I1g structure.

A still further object of the invention is to provide specific gravity le s than that of the water.

It is another object of the invention to provide a barrier which is considerably inexpensive because it is obtained from staples or waste from synthetic plastic materialsf such as propylene fibers and polystyrene, whioh are otherwise unusable* The above objects and advantages of the invention will become more apparent from the following detailed description thereof and from the accompanying drawings, in whlchi Figure 1 is a cross-sectional view of the barrier of the .Invention} and Figure 2 is a perspective view of the barrier, showing the position in the barrier of the Various components tl$ffeof.

Referring no to the accompanying drawings, the barrier, which may be shaped as illustrated, namely or|p3S-sectionally circular, or in any other shape desired, consists of a central rope 1 of propylene fiber and of a suitable diameter, surrounded by a plurality of rings 2 of polystyrene. These rings may be monolithically built or may consist of granular particles suitably contained in such a manner as to retain a low specific gravity and, therefore, the ability to float. The rope 1 and the rings 2 are, in turn, completely enclosed in& layer of plastic materia 3, composed^ of a mixture of staples or waste poly from fibers of/propylene and granules of polystyrene,, the whole poly mixture bein contained in. a net 4 of/propylene fiber, A further peripheric enclosure 5 completes the barrier of the invention. Enclosure 5t of suitable thickness, consists of stales or waste from stales of/ ro lene fibers and is contained by an outer netting 6 of/ ropylene fiber.

The above-described barrier, which may be of any desired diameter and length, has an over-all, specific gravity such as to allow it to float in the water approximately to the level of the central rope 1, The relationship between immersed and non-immersed portions of the barrier is a direct result of .poly the ratio of polystyrene and/propylene material employed.

The barrier ma be located along the beaches as a protection against pollutants, o it may be located at a greater distance from the shoreline so as to define an area within which to discharge the polluting products from tankers. In any event, the barrier serves to confine the polluting agents and to prevent them from diffusing on the water surface,because of the barrier s high absorptive capacity and of the irreversible process of water-purification.

It is well understood that the dimensions of the barrier, the thickness of the floating layers of material, may vary depending o the requirements of the particular use;

Claims

WHAT IS CLAIME IS;

1. Floating barrier for arresting, confining and absorbing water pollutants in suspension therein comprising . poly (a) a central rope of/propylene fiberf (b) a first layer of polystyrene surrounding said central ropeJ .poly (c) a second layer of a mixture of/propylene and .poly granular polystyrene, said/propylene being selected from the group consisting of staples and fiber waste, said mixture being /Poly contained within a netting of/propylene fiber, said second layer surrounding said first layerj poly ,(d) a third layer of/propylene selected from the group consisting of staples and fiber waste and contained . with ' .poly a netting of/propylene fiber, said third layer surrounding said second layer.

2. ≥. The barrier of Claim 1, wherein said first layer is selected from the group consisting of monolythic blocks of polystyrene and granular polystyrene.

3. The barrier of Claim 1, wherein the elements thereof are so assembled that some elements are pollutan -absorbers, while others are waterproof, the combination of said elements being such that said barrier is submerged only with about one half of its volume. '■ "■ ·■ ' Attorneys for A; licants.
