A barrier member for an oil spill barrier configured for retaining one or more weights when assembled or combined with a second barrier member to form a barrier unit. A first barrier member has a first side for facing away from the second barrier member and a second side opposite the first side for facing towards the second barrier member in the barrier unit, the second side includes a substantially planar area for abutment to the second barrier member. The second side has at least one recessed region for receiving the one or more weights, the recessed region being recessed from the second side in a direction towards the first side relative to a plane of the substantially planar area. The second side has first and second elongate half-channels disposed to opposing sides of the at least one recessed region.

A submersible sieve apparatus provided with an exoskeletal frame enveloping a filter element and a detached post-filter backing; positioned to strain a lotic stream of entrained sediment prior to or upon being deposited. The frame can positioned and manipulated for greater efficiency. The filter and backing will take the shape of the frame and the backing may or may not be attached.

A resiliently deformable containment structure having an open bottom end and a raised center portion. A central hub, situated centrally in a textile containment sheet, is provided. A plurality of elongate inflatable beam members are arranged circumferentially around the central hub, each extending radially outwardly and in a downwardly-extending manner therefrom and each underlying or overlying the textile containment sheet to support, when inflated, the textile containment sheet in a downwardly-extending shape to form an enclosure having an open bottom end. Distal ends of the inflatable beam members are tethered to one or more anchor members situated below the open bottom end of the dome structure. The structure is suited for placement above and over a compromised sub-sea structure for collecting and recovering to surface fluids which may be leaking therefrom. A method for containing and recovering such fluids from a compromised sub-sea structure is further disclosed.

An oil-collecting apparatus includes: a body including an inlet through which a liquid is introduced, a first outlet through which purified water generated from the liquid introduced through the inlet is discharged, and a second outlet through which materials collected from the liquid are discharged; and a filter arranged at the first outlet of the body and generating the purified water by collecting the materials included in the liquid by allowing the liquid introduced through the inlet to pass therethrough.

The present disclosure relates to a fence having a hydrophilic material, and according to an embodiment of the present disclosure, there is an effect in collecting oil or hazardous & noxious substances quickly and efficiently while minimizing the pressure caused by water, by forming the fence from a material that allows water to penetrate while disallowing oil to penetrate.

Additionally, there is an effect in preventing oil spill phenomena caused by damage or unbalance of the fence by reducing the water pressure applied to the fence due to water penetration even when a strong water pressure acts on the fence, for example, strong tidal currents occur and the fence is towed at high speeds to collect oil.

A floatable, portable and readily deployable apparatus used in a surface water body for the collection, mixing, separation, containment and removal of total solids from fluid in surface water by settling, sorption, floatation or filtration of total solids from fluid entering or induced to flow into the apparatus. Separation of total solids from fluid can include the use and recycling of commercially available or proprietary biologic, chemical and/or physical substances and processes to increase the rate and percentage of total solids removed from fluid in the apparatus.

An oil containment system aboard a vessel includes a pneumatic system to provide power to a winch and reel assembly containing boom whereby the pneumatic supply is capable of simultaneously powering the winch-reel assembly for boom deployment through inflatable gas fed to a pneumatic motor while also inflating the boom. The inflation of the boom is accomplished by diverting, all or any portion thereof, the inflatable gas from a pneumatic supply through a hose that runs concurrently on the outside of the boom. The pneumatic supply originates from a single pneumatic system powering both the winch and reel assembly as well as associated brake and feeding inflatable gas pressure to the inflation hose running concurrently with the boom. The system can be utilized to confine a discharge of a floating material such as hydrocarbons floating on the surface from a vessel or structure.

A floating turbidity barrier includes a first barrier section and a second barrier section. Velcro is affixed to a portion of the first barrier and to a portion of the second barrier. The Velcro of the first barrier section and the Velcro of the second barrier section are connected together.

A method, apparatus, and system are provided, utilize a floating treatment wetland designed specifically for the sequestration of microplastic debris (i.e., plastic particles under 5 mm) from active water systems. This process can be achieved through the careful selection of a root structure combined with the development of a robust housing for the wetland pad, so that it may operate effectively in fast current conditions. Existing phytoremediation wetlands are typically deployed in static aquatic environments like reservoirs or lakes, and cannot remain stable in currents beyond speeds of 2 m/s. This currently limits their application in most rivers that typically reach speeds beyond 6 m/s, especially during storm surges. To overcome this, disclosed is a hydrodynamic fiberglass frame to encase and stabilize the floating treatment wetland during storm surges. The design of this frame may be adapted to encourage optimal flow to the underside of the wetland, in order to maximize the amount of water exposed to the wetland's biofilm filter.

Automatic remove equipment for disaster blooming marine organisms of sea water intake channel belongs to the field of marine environmental engineering and equipment. The equipment comprises a cod-end of collecting net, a saw blade at the end of net, a fixation and support system, a submersible spiral pump, a transport pipe system, a separating system on coast and floats. The equipment collects the disaster blooming marine organisms in the sea water channel into the bottom of a cod-end of collecting net, and cuts and decomposes the collected disaster blooming marine organisms by using a saw blade at the end of net under the combined action of the water flow power and the suction pressure of a submersible spiral pump. Fragments after cutting are sucked by the submersible spiral pump and delivered to a coast, and are subjected to solid-liquid separation by a separating system on coast and then are centrally disposed. The equipment is sturdy and durable and can resist corrosion of the sea water environment; and the equipment can efficiently collect and remove the disaster blooming marine organisms in the industrial sea water intake channel automatically, thereby saving labor cost, ensuring normal operation of the industrial system and increasing production benefits.
