Abstract: A natural water circulation apparatus reduces the evaporation rate of a body of water by lowering the surface temperature and improves the quality of the water. The apparatus includes a collector which extends above the normal surface level of the water to capture surface waves. The captured water is conveyed from the epilimnion of the body of water to the hypolimnion of the body of water through a lower opening in the collector.

Abstract: An atmospheric bioremediation system and method uses preformed gel-like agar sheets or equivalent biological growth medium, composed to selectively enhance the growth of microalgae in defined environmental conditions. Agar is heated and liquefied and soluble iron is added to the agar in predetermined proportions. The agar solution is also modified for salinity concentration and ph in order to conform to the levels found in the marine environment to which the agar sheets are to be introduced. This is done in order to provide a slow-time release of the iron to prevent premature precipitation. Also, the osmotic variance needs to be equalized by salinity concentration and ph adjustment to prevent premature osmotic migration of the iron molecules when in gel form. Once formed, the gel sheets are transported to defined bodies of water, e.g.

A vessel includes a water intake system, a reverse osmosis system, a concentrate discharge system, a permeate transfer system, a power source, and a control system. The concentrate discharge system includes a plurality of concentrate discharge ports. A water intake system installed on a sea-going vessel positioned on the surface of a body of water includes an apparatus for taking up seawater from the body of seawater. The apparatus includes a water intake member, a water intake positioned on the water intake member, and an impingement, entrainment, and entrapment mitigation device at least partially surrounding the water intake and including a plurality of apertures sized to prevent entry of marine organisms into the water intake.

Abstract: A vessel travels over a surface of a body of water or a waterway to collect waste on and/or close to the surface. A retainer that traps and retains the waste is activated by creating a water flow channel that is connected to a water inlet and a water outlet on the vessel. The retainer is on at least one trajectory of said channel. Waste is collected without using a specific pumping or gathering device.

Abstract: A portable filtration device filters water from a body of water within which the device can be buoyantly supported. The device generally comprises an inflatable floatation chamber arranged to support the device to float on the body of water and a filtration housing arranged to be suspended from the floating chamber in the body of water. The filtration housing has an inlet, an outlet, and a filtration medium arranged to filter water passing therethrough from the inlet to the outlet. The inlet is arranged for communication with the body of water and the outlet is arranged for communication with a filtered water reservoir for providing potable water to the reservoir.

Abstract: A vacuum skimmer for ponds, swimming pools or similar bodies of water has housing with an intake opening and a dirt collecting container arranged downstream for collecting coarse materials. The water to be purified is sucked in through the dirt collecting container by a pump arranged downstream. The intake opening is provided on one housing side. The vacuum skimmer is movable in such a way that the intake opening upon operation of the vacuum skimmer can orient itself in different directions. The vacuum skimmer has an aeration device by means of which air can be blown into the water.

Abstract: A system for removing dissolved contaminants, particulate contaminants, and oil contaminants from industrial waste water, the system including a gas floatation and primary oil contaminant removal subsystem including a tank for receiving a flow of the industrial waste water and a flow of gaseous microspheres, wherein the gaseous microspheres combine with oil droplets in the waste water to form flocs which float to the surface and are removed to provide processed waste water with the majority of the oil contaminants removed, and a contaminant removal subsystem for removing dissolved contaminants, particulate contaminants, and any remaining oil contaminants from the processed waste water.

Abstract: Circulation systems for ponds, lakes, or other bodies of water. In one set of embodiments, water is drawn up from the depths of the body for exposure to the atmosphere and to generate an overall, high flow circulation pattern throughout the entire body. In other embodiments, the circulation in the body of water is primarily limited to an upper aerobic zone with only small and controlled volumes from a lower anaerobic zone being brought up. Each system preferably includes a flotation platform, dish, impeller, and draft tube with specific modifications to the various systems to adapt them for use in a variety of environments.

Abstract: A cruising aeration apparatus and a method are described. The cruising aeration apparatus comprises an aeration device for circulating the water in an aquatic pool, at least one conducting element connected to the aeration device for conducting the aeration device along a traveling route, and a controller. The at least one conducting element can be a rope or a float loop used as a separation line of a swimming pool. The pool water is drawn and pressurized by the aeration device and then ejected from nozzles of the aeration device. The nozzles on the front side and the rear side of the traveling route of the aeration device produce different counterforce. The aeration device is driven along the traveling route by the difference between the counterforce of the front side and the rear side of the traveling route. At least one switch is installed to control the opening and the closing of the nozzles, and is located on the side of the aeration device providing larger counterforce.

Abstract: Circulation systems for ponds, lakes, or other bodies of water using a flotation platform, dish, and impeller. One embodiment has a connecting arrangement between the drive motor and the impeller that permits the two to be easily and quickly coupled and uncoupled. The connecting arrangement also is designed to accommodate slight misalignments between the shafts. An arrangement to adjust and calibrate the depth of the inlet to the draft tube is disclosed. The system further includes solar panels that can be pivotally swung outwardly to open positions, angularly adjusted about a horizontal axis, and mounted to face toward the central axis of the flotation platform rather than away from it. Arrangements are further provided to monitor and control the components of the system including remotely from shore.

Abstract: Floating wetland structures of the invention are generally formed from one or more floatation panels made of a plurality of polymeric foam particles arranged in a piled laminate structure. The foam particles are arranged within the piled laminate structure so as to define void pathways between at least a portion of said foam particles. The void pathways within the piled laminate structure are of sufficient size and quantity to allow rainwater to flow through and of such an orientation to allow for the roots of vegetation to easily penetrate the structure.

Abstract: An apparatus, system and method for removing and treating contaminated materials on a bottom of a body of water and introducing growth packets to revitalize the treated bottom of the body of water. The structure may comprise a vessel with an open face. The vessel may be lowered down to the bottom of the body of water with the face facing down. As a result, the vessel and the bottom form an isolated space. The structure may comprise at least one agitating device(s) for stirring up the materials inside the vessel so as to form a mixture containing the sediment materials which in turn contain the contaminants. Multiple at least one pipe(s) may be coupled to the vessel for transporting the mixture out of the vessel for processing (filtering, treating with chemicals, etc.) so as to neutralize or eliminate the contaminants in the mixture. Then, the treated mixture can be returned to the inside of the vessel via the at least one pipe(s).
