A marine apparatus for collecting waste, including a vessel frame; at least one float or ballast tank mounted on the vessel frame; a removable frame configured to receive a waste collector; at least one guide mounted on either the vessel frame or the removable frame; and at least one slide mounted on the other of the vessel frame or the removable frame, said at least one slide including a channel closed at one end and open at an opposite end, the open end forming a receiving end for receiving a respective guide.

Disclosed is a hydrophilic material oil fence having a double-porous mesh. The hydrophilic material oil fence having the double-porous mesh includes a floating body floating on a water surface, and a skirt coupled to an upper portion and a lower portion of the floating body and made of a hydrophilic material through which a hydrophilic fluid selectively passes. A mesh hole size of a partial region of the skirt and a mesh hole size of the other region of the skirt are different.

A system, method for forming, and a method of manufacturing a boom for the containment of contaminants, wherein the system includes a cover and an adsorbent material disposed within the cover. The adsorbent material may be formed of at least one sheet of flexible, adsorbent fabric folded upon itself within the elongated cover. Additionally, the adsorbent material disposed within the elongated cover may form a non-cylindrical cross-section, and the flexible, adsorbent fabric forming the adsorbent material may be at least partially a polyester material.

A marine apparatus for collecting waste, including a vessel frame; at least one float or ballast tank mounted on the vessel frame; a removable frame configured to receive a waste collector; at least one guide mounted on either the vessel frame or the removable frame; and at least one slide mounted on the other of the vessel frame or the removable frame, said at least one slide including a channel closed at one end and open at an opposite end, the open end forming a receiving end for receiving a respective guide.

A method for absorbing liquids, such as liquid hydrocarbons, includes applying recycled carpet material to the liquid. The recycled carpet material is prepared by shredding carpet and removing fibers from the shredded carpet to obtain carpet backing material. The carpet backing material may be further treated to remove fibers. The carpet backing material is then applied to the liquid.

The invention relates to a hydrophobed porous oil binder in the form of a nonwoven fabric composed of lignocellulose-containing raw materials having a biologically functionalized surface for removing mineral-oil-based contaminants in seas, rivers, inland waters, and stormwater basins or wastewater treatment plants, wherein the density of the oil binder is 10 to 900 kg/m.sup.3, the oil binder is 1 to 25 mm thick, the broad surface of the oil binder has a dimension of 9 to 200 cm.sup.2, the porosity of the oil binder is 30 to 96%, measured with respect to the total fraction of the oil binder, and the flexural strength of the oil binder is at least 1.5 N/mm.sup.2.

The invention relates to a device for taking up oil from a water surface, comprising a container for receiving the oil and an oil-transporting means, wherein a portion of the oil-transporting means can be brought into fluid communication with the water surface and another portion of the oil-transporting means is disposed within the container, wherein the oil can be transported into the container via the oil-transporting means, wherein the oil-transporting means is formed from a hydrophobic fabric, the surface of which comprises filament-shaped and/or grid-like structures which are designed in such a way that they retain a gas layer on the surface of the hydrophobic fabric under water. The invention further relates to a corresponding method for taking up oil from a water surface.

A sorbent-based oil skimmer is configured to collect oil from an oil layer and passively deposit the oil in an encasing, where the oil can be continuously or periodically removed. The oil skimmer includes an encasing and a sponge that is partially enclosed within the encasing. The sponge has a top sheet in contact with the oil layer and a shell connected to the top sheet, where the shell extends into the encasing. Oil collected by the top sheet is conveyed through the shell, where it is deposited into the encasing under the force of gravity. In some applications, the sponge is manufactured from a silicone-based polymer that has been impregnated with carbonaceous material. The skimmer may optionally include counterweights, ballast tanks, buoyancy adjustment systems and propulsion modules.

The present disclosure provides a scum absorbing device for absorbing scums in water. The scum absorbing device includes a front absorbing body, the front absorbing body includes: a first front layer defining a plurality of first via holes; a second front layer; and a third front layer, connected between the first front layer and the second front layer, the third front layer is capable of absorbing or capturing scums in water.

A floating weir skimmer comprises a collecting box (10), a weir plate (11) and an inner buoy (5). Said collecting box (10) comprises a baffle plate (3) and a trough (1). A guide rail (6) is arranged inside said trough (1). An inner buoy (5) is arranged inside collecting box (10), and a guide pulley (14) is arranged on said inner buoy (5), enabling said inner buoy (5) to slide on said guide rail (6). A supporting member is further arranged on said inner buoy (5). One end of said weir plate (11) is carried by said supporting member, and the other end is in rotation connection with said trough (1).
