A waste management system for plastic or other material floating on the surface and in the subsurface of a body of water. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is frozen to a temperature at or below minus fifty degrees Fahrenheit, using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon may be recycled or used as fuel by the ship. Water may be used by the ship or returned to the ocean.

A portable water conditioning system is provided that includes a water conditioner, a first sensor, a second sensor, and a controller. The water conditioner has a plurality of conditioning stages that condition water. The plurality of conditioning stages include, in a direction of flow of the water through the water conditioner, a reverse osmosis stage and a deionizing stage. The first sensor detects a first condition of the water before the reverse osmosis stage. The second sensor detects a second condition of the water after the reverse osmosis stage. The controller is in communication with the first and second sensors and determines a health status of the reverse osmosis stage based the first and second conditions. The first and second conditions each include a level of total dissolved solids of the water.

Systems, apparatus and methods useful for collecting debris from a body of water on a vessel having at least one cargo compartment and at least a first pump fluidly coupled to at least one cargo compartment and configured to concurrently draw water and debris from the body of water into, and remove water from, the cargo compartment(s) include at least a second pump, distinct from the first pump and configured to remove debris from at least one cargo compartment.

A method of providing a dispense purified water stream from a water purification apparatus involving passing a water inlet stream through a first water purification station to provide a first internal purified water stream, passing the first internal purified water stream to an internal reservoir, and providing a second internal purified water stream from the reservoir, passing the second internal purified water stream into a recirculation loop, measuring the conductivity of the second internal purified water stream; passing the second internal purified water stream to a second water purification station to provide a third internal purified water stream passing the recirculated water return stream into the internal reservoir; calculating the purity of the first internal purified water stream using the measurement of the conductivity of the second internal purified water stream.

Methods and systems including processing dredge spoils to reclaim soil therefrom. The techniques may include a feed system for receiving dredge spoils, a dewatering system for removing water from the dredge spoils, and a grinder/mixer for grinding the dredge spoils from the dewatering system while mixing the dredge spoils with one or more additional materials.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex, with surrounding entertainment, educational, sports, and commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

A modular support system includes a central core and operation modules arranged radially around the central core. A first operation module is configured to receive water to be treated. A second operation module is disposed under the first operation module and is configured to receive the water and to perform a first type of water treatment. A third operation module is disposed under the second operation module and is configured to receive the water and to perform a second type of water treatment that is different from the first type of water treatment. A fourth operation module is disposed under the third operation module and is configured to receive and store the water for usage.

An apparatus for removing a layer of sediment which has settled on the bottom of a large water body that includes a structural frame configured to contain a bottom water flow and avoid a re-suspension of sediment outside the vicinity of the structural frame. The structural frame has a control zone configured for containing liquid and suspended particles dispersed during removal of bottom sediment in a suctioning area that is at least about 3 square feet. A sediment removing vacuum unit is operably associated with the structural frame to conduct a suctioned bottom water flow.

The invention relates to a device for services related to providing hot water, to water treatment, to the cleaning of any fixed or mobile surfaces like lines for proving potable water or food liquid, remarkable in that it is mobile, comprises an internal chassis housing in the lower part a tank for recovering possible fluids and a subassembly for producing hot water with at least one condensing boiler associated with at least one module for supplying gas formed by a plurality of gas cylinders of the carburation type storing in their internal volume the gas in the liquid state in the lower part and in the gaseous state in the upper part, said gas cylinders being disposed in the internal chassis substantially horizontally and with the opening orifice oriented upwards so that the end of the pipe for passage of the gas opens onto a larger elongated gaseous part.

A system for desalinating water is disclosed. The system comprises a subsea reverse osmosis unit located beneath the surface of a body of water, a first liquid column comprising seawater, a second liquid column comprising desalinated water with a salinity less than seawater, and a brine discharge outlet. Due to the difference in density between the seawater and the desalinated water, the gravitational hydrostatic pressure of the first liquid column may be greater than the gravitational hydrostatic pressure of the second liquid column. At least a portion of the pressure difference for reverse osmosis desalination may be provided by the difference in gravitational hydrostatic pressure between the first liquid column and the second liquid column. A significant reduction in desalination energy consumption may be enabled by discharging the brine at an elevation lower than the maximum elevation of the first liquid column or the second liquid column.
