Abstract:
A petroleum from oil/water mixtures extraction method for use as an adjunct to current stationary active second containment methods for industrial oil spill accidents, and as an adjunct to currently used equipment for residual oil removal in clean-out measures for, among others: canal barges, hazmat trucks, oil storage tanks, oil tankers, oil transportation railroad cars, river barges, as an on-board separation system for petroleum based bilge, and in coastal and inland waterways clean-up from oil spill accidents.
Abstract:
A water distribution system including a water storage tank, a water treatment unit, a diverter valve, and interconnecting water conduits arranged so that the same water treatment unit can be used to treat water supplied from a fill port to the storage tank during a fill operation, as well as water leaving the storage tank for supply to one or more points of water use during a supply operation. A diverter valve is provided which is movable between a fill position wherein the water treatment unit is in fluid communication with the fill port and not the point of water use device, and a supply position wherein the water treatment unit is in fluid communication with the at least one point of water use device and not the fill port. When the diverter valve is in the fill position, water supplied to the fill port can thus flow through the diverter valve and to the water treatment unit for treatment then to the storage tank for storage. When the diverter valve is in the supply position, the water from the storage tank can be delivered using means for pressurizing water to the same treatment unit for treatment, then through the diverter valve and to the at least one point of water use device.
Abstract:
A working pontoon raft has frame that supports a plurality of high speed evaporator fans. An on board pump draws wastewater from under the raft and feeds it to the fans. Large amounts of wastewater from industrial reservoirs, such as oil drilling reservoirs, are evaporated into the air in an environmentally friendly manner. Power is supplied to the raft via hydraulic lines. A land base generator supplies the hydraulic power. The entire system fits on a custom trailer.
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:
The invention relates to a method for oxidative treatment of aqueous liquids by means of oxidants. In this method, the aqueous liquid is passed through an electrolysis reactor, in which highly aggressive oxidants (OH—, O3, H2 O2) are produced in the electrochemical decomposition of the water. Black and/or grey water is used as the aqueous liquid, which is liberated from coarse particles and mechanically broken up thereafter, before it is passed into the electrolysis reactor. Gaseous portions are released and inorganic residual components are filtered out. The remaining residual liquid, which consists substantially of water, can be introduced into a fresh, wash- and/or rinse water system.(only FIGURE)
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. 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. A method of desalinating water on a sea-going vessel positioned on the surface of a body of seawater includes the steps of intaking seawater from the body of seawater into the vessel through a first screen including a plurality of apertures sized to prevent entry of marine organisms into the water intake, and removing salt from the seawater taken into the vessel to yield desalinated water and a concentrate.
Abstract:
The invention described herein contains two aspects, usable together or separately, that address the needs in the art described above, namely a first aspect that relates to the provision of a transportable water purification system that can be contained on a passenger transport vehicle, and that can use, but does not require, continuous, real-time monitoring, and a second aspect that relates to the use of UV purification of the water as it is uploaded to the passenger transport vehicle after a single pass through the UV chamber.
Abstract:
Water-treatment systems and techniques are addressed. These systems and techniques contemplate monitoring water-quality-related information and creating residual disinfectant in recirculating water loops. Such circulating residuals also may help control biofilm otherwise likely to be present in the conduits and other equipment through which the water passes. Heaters may be employed as parts of the systems, and pressure differentials may be exploited to control water flow. Principally for use on-board aircraft operable at substantial altitude, the systems and methods may nevertheless be utilized in other vehicles or vessels or otherwise as appropriate or desired.
Abstract:
Water, preferably fresh potable water, is electrochemically, e.g. electrolytically, treated to achieve disinfectant properties. The electrochemically treated water is sprayed onto the toilet seat and directed into the toilet bowl for each flush cycle of an aircraft toilet system, so as to clean and disinfect the toilet seat and the toilet bowl. The electrochemically treated water has a direct germ-killing effect on the seat and bowl, and also disinfects the arising wastewater that is conveyed to and stored in a storage tank. For flushing the toilet bowl, the electrochemically treated water may further be mixed with reused graywater, which is thereby disinfected.
Abstract:
Offshore facilities, systems, and methods for treating wastewater have been developed. An offshore wastewater treatment facility include wastewater treatment components (for preliminary treatment, primary treatment, secondary treatment, and/or advanced treatment); a means for moving wastewater from a land-based site to the facility; a means for removing treated wastewater from the facility; and a means for removing sludge from the facility. A method of treating wastewater includes: transporting wastewater from a site on land to a wastewater treatment facility located offshore in a body of water, and subjecting the wastewater to preliminary treatment, primary treatment, secondary treatment, and/or advanced treatment.
