A barrage with a function of collecting floating garbage on a water surface is provided. It includes a first dam body as a main body of the barrage provided with multiple built-in low water level drainage channels and high water level drainage channels, a second dam body provided with multiple notches for converging floating garbage on the water surface, a garbage collecting and storing equipment arranged between the first dam body and the second dam body and a solar power generating equipment. The garbage collecting and storing equipment maintains running of the garbage conveyor belt by utilizing electric energy provided by the solar power generating equipment, thereby collecting garbage in a garbage pool beside the barrage. It not only has conventional functions of the barrage, but also greatly saves cost of manually salvaging garbage and avoids water pollution caused by accumulation of garbage on the river surface.

Disclosed herein is an apparatus (10) for remediation of a site contaminated by an oil spill. The apparatus (10) comprises a porous capsule (12) encapsulating material (14) for sorbing oil. The material (14) comprises granules of an at least semi-open cell polymeric foam, the granules being less than 10cm3 in size. Ingredients from which the polymeric foam is formed comprise acrylonitrile butadiene rubber as a major constituent thereof by weight.

A natural zeolite block for improving water quality that is capable of being built in rivers, streams, and reservoirs having point and non-point pollutant sources to purify the water polluted by pollutants, to remove the eutrophication in the water to prevent the occurrence of green and red tides, and to consistently purify heavy metals and all kinds of harmful substances flowing into the water and to a method for manufacturing the same.

A universal chemical processor (UCP) including a reactor vessel having a central longitudinal axis and main chamber comprises a first inlet port for a main feedstock, a second inlet port for a fluidizing medium and a third inlet port for one or more reactants. The UCP also includes a reactive radioactive chemical processor (R.sup.2CP) that contains a radioactive element positioned extending along the longitudinal axis in the main chamber. In operation, a fluidized bed can be supported in the main chamber when a fluidizing medium and feedstock are supplied to the main chamber through the first and second inlet ports and the radioactive element of the R.sup.2CP emits ionizing radiation that is capable of ionizing feedstock and reactants, inducing chemical reactions, and sterilizing and decomposing any organic materials within a radiation zone.

An ocean alkalinity enhancement (OAE) system that reduces atmospheric CO.sub.2 and mitigates ocean acidification by electrochemically processing feedstock solution (e.g., seawater or brine) to generate an alkalinity product that is then supplied to the ocean. The OAE system includes a base-generating device and a control circuit disposed within a modular system housing deployed near a salt feedstock. The base-generating device (e.g., a bipolar electrodialysis (BPED) system) generates a base substance that is then tested and processed (e.g., mixed/diluted with processed feedstock solution, seawater or another saltwater solution and/or reacted with CO.sub.2) to generate the ocean alkalinity product. The control circuit controls the base-generating device such that the alkalinity product is supplied to the ocean only when supplying the alkalinity product will not endanger sea life. Modified BPED systems include features that facilitate autonomous system operations including enhanced maintenance cycle operations and a reduced reliance on external fresh water sources.

The invention provides an integrated water treatment system suitable for use in the treatment of contaminated water, wastewater, potable water, aquaculture, industrial water and polluted water bodies. An integrated water treatment system according to at least one embodiment of the invention comprises a plurality of modules adapted to float in a body of water integrating a plurality of different attached growth biofilm media types positioned within a plurality of water flow paths and circulations. The conditions provided by a multiple of media types and plurality of flow paths creates a multiplier effect increasing the number of treatment zones and an increased diversity of interconnected treatment process zone types. Embodiments of the invention provide a diversity of conditions and biological habitats establishing a poly-culture of producers, consumers and higher organisms in an ecosystem of biological treatment processes, with complex metabolic pathways and food chains increasing treatment efficiency and the range of pollutants which may be effectively treated. Modules comprised in the system are adjustable in operational rate, series, and timing, and are movable in configuration and/or proximity providing a new type of adaptable, re-configurable and adjustable multi-zone, integrated ecological biofilm water treatment system.

Provided herein are compositions and methods that can remove, metabolize, or degrade a hydrocarbon in an area that is contaminated by hydrocarbons. Methods for bioremediation of an area such as an area of land, a body of water, or a shoreline that are contaminated by a hydrocarbon, such as from a crude oil spill are also described. The compositions and methods described herein can be used on natural flora and fauna as well as manmade materials that are contaminated by a hydrocarbon.

A solar boat for easy collection of spilled oil and garbage of the present disclosure includes a cabin unit, a boat body consisting of a pair of ship bottoms having a structure that is symmetrical left and right and spaced apart below the cabin unit, a solar panel unit provided above the cabin unit and configured to convert solar energy into electrical energy, a collection and transfer unit provided between the pair of ship bottoms, driven by the electric energy supplied from the solar panel unit, and configured to collect spilled oil and garbage into the inside of the boat body, a garbage storage unit, and a spilled oil storage unit, wherein the collection and transfer unit comprises a rotating conveyor belt, and an oil adsorption member and a collection member that are attached to and detached from the conveyor belt, and the solar boat for easy collection of spilled oil and garbage of the present disclosure has an effect of having excellent work efficiency by simultaneously including an oil adsorption member and a collection member that are attached to and detached from a conveyor belt and simultaneously proceeding with collection of spilled oil and collection of garbage on the water, and an effect of being able to separate the spilled oil from the oil adsorption member, the collection member, and the garbage and easily move the spilled oil to the spilled oil storage unit by including a steam spray nozzle configured to spray hot steam at the end of the conveyor belt.

This disclosure relates generally to waste collection, storage, and retrieval from water. Aspects of this disclosure relate to submersible cleaning vehicles, filter systems, ships, communication systems, autonomous navigation, and computer systems. The submersible cleaning vehicle can navigate underwater to capture waste in filters. Abase station can support the submersible cleaning vehicle.

A method for producing clean water from a contaminated water source, the method comprising the steps of: a) locating a clean water generating device in fluid communication with the contaminated water source, the clean water generating device including a reaction chamber containing an ionic solution; b) transferring contaminated water from the contaminated water source into the reaction chamber through an inlet in the clean water generating device; c) generating an electrolysis reaction within the reaction chamber; d) removing gas generated by the electrolysis reaction from the reaction chamber through an outlet of the reaction chamber; e) combusting the gas generated by the electrolysis reaction; and f) collecting clean water generated by the combustion of the gas.
