Abstract:
A water distribution apparatus comprises a water user outlet facility and a water re-circulation loop. The water re-circulation loop comprises a water supply, a water pump for establishing and maintaining a flow of water in the loop, a water delivery path extending from the pump to a water user outlet facility, a water return path extending from the water user outlet facility to the water supply, and a thermal disinfection apparatus disposed in the water delivery path for improving the potability of the water within the loop.
Abstract:
Systems, methods, and apparatus for desalinating water are provided. 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.
Abstract:
A wastewater treatment system for use on a marine vessel comprising an aerobic fixed film biological reactor, a tubular flocculator and a dissolved air flotation (DAF) unit. The process units desirably include means for reducing erratic movement of the wastewater due to sea-induced movement of the marine vessel. The DAF unit includes a plurality of inclined baffles arranged to create a plurality of parallel inverted U-shaped flow paths that effect combined co-current and counter-current flotation separation while reducing erratic movement of the wastewater. The selection of process units and operating conditions advantageously reduces the footprint of the wastewater treatment system and reduces cost and complexity associated with the handling of wastewater treatment chemicals.
Abstract:
An anti-fouling system for offshore drilling structures which injects metallic ions into seawater pumping systems. An ion generator may be positioned at various positions including the strainer basket of one or more of the seawater pumps or at various positions in the system. As well, ion generators may be skid mounted and/or otherwise centrally located and connected by controllable valves to various treated water injection points, whereby the flow rates are determined and ion concentrations are maintained at desired levels throughout the system, regardless of different pumping rates.
Abstract:
Wastewater is treated on at least one apparatus positioned at a location on the surface of a body of seawater wherein a wastewater intake system takes in wastewater into the apparatus, the wastewater is treated on the apparatus to yield treated wastewater and sludge, and the treated wastewater and/or sludge is diluted with seawater prior to being discharged into the body of seawater. The wastewater treatment systems and methods can also be combined with desalination and/or power generation. In combination with desalination, the concentrate produced from the desalination process is mixed with treated wastewater or sludge prior to discharge to bring the resulting mixture to a salt concentration closer to the body of seawater than the unmixed concentrate, treated wastewater, or sludge. Combustible gases produced by the wastewater treatment process can be used to fuel a power generation system that can be used to produce electrical power for use by systems on the apparatus or transferred off the apparatus for other uses.

Abstract:
It has been discovered that a mechanical flotation system having only two cells can be nearly as efficient as one having more cells, yet provide an apparatus with a considerably smaller footprint, significantly reduced capital and operating costs, as well as be resistant to floating oil recovery platform wave effects. The dual-cell mechanical flotation system has, in sequential order, an inlet chamber and two gasification chambers or cells, each with at least one gas ingestion and mixing mechanism, and a discharge chamber. A common primary skim collection channel atop the partition dividing the gasification chambers efficiently channels away the bulk of the floating collected matter. At least one baffle depending from the top of the vessel near the primary skim collection channel helps dampen the action of the fluid containing the suspended matter when the vessel is affected by wave motion against the floating oil production platform.
Abstract:
A waste treatment system for use on a vehicle having an exhaust manifold, the waste treatment system comprising a holding tank for receiving waste from a head, a galley, a shower or a bilge tank. At least one macerator is connected to the holding tank such that the macerator grinds the waste from the holding tank and recirculates it, as appropriate. A reducer is connected to the at least one macerator for reducing the size of the output of the at least one macerator. A centrifugal separator separates the relatively large waste particles coming from the reducer from the relatively small waste particles and liquid waste and recirculates the relatively large particles back to the holding tank. The remaining particles are sent to an injector pump that injects the waste, through an injector nozzle, into the exhaust manifold of the vessel. A control module controls the operation of the system based on various parameters, the parameters derived from various sensors.
Abstract:
An on-board treatment device and method for use on watercraft and other mobile vessels are provided. The system includes a treatment tank which is connected to the head and a bioreactor and a feed pump which are connected to the treatment tank. A macerator pump breaks up solids in the wastewater before the wastewater enters the treatment tank. During a treatment cycle, a head valve prevents any further flow of wastewater from the head into the treatment tank. Also during a treatment cycle, a bioreactor 3-way valve will be set so that the feed pump will flow wastewater from the tank, through the bioreactor, and back into the treatment tank. The bioreactor will include microorganisms which are adapted to the treatment of human waste. When the wastewater has been sufficiently treated, the feed pump will be turned off so that solids in the wastewater can settle out. After the solids have settled out, the feed pump is turned on and the bioreactor 3-way valve is set so that the now treated wastewater is discharged overboard. In a preferred embodiment the bioreactor includes an aerator.
