Abstract:
This infiltration intake system for a revetment wall includes a structural body, set on an outer wall surface of a revetment wall, including a filter storage portion, a filter stored in the filter storage portion of the structural body, and a water guide portion guiding treated water passing through the filter toward the side of an inner wall surface of the revetment wall.
Abstract:
A water directing and distribution system (WDDS) that functions in combination with a natural or man-made water source. The WDDS includes a main pipe with an intake and a termination point. The main pipe is placed into or adjacent to the water source, at a depth below the water source's surface. Water from the water source enters the pipe at the intake and flows through the pipe by force of gravity. The water is maintained within the pipe and directed through the pipe at a lower level than the water source's origination point. Water from the pipe can be accessed via taps placed along the pipe. The water can also be directed to a water storage structure(s) and can be purified for human or animal consumption.

Abstract:
A potable water producing system for disposition at a salt water body and methods of producing potable water are provided. The system includes a wave energy conversion system (AWECS) and a portable filtration system. The AWECS forms a floating articulated barge having an onboard desalination system including reverse osmosis membranes. The filtration system is a sand filter residing on a damping plate submerged in the salt water body and filters the adjacent salt water for providing filtered salt water to the onboard desalination system. Wave action on the articulated barge provides energy to pump and pressurize the filtered salt water from the sand filter to the reverse osmosis membranes to produce potable water. The wave action on the articulated barge effects shaking of the reverse osmosis membranes, thereby rendering them self-cleaning. The potable water can be used for various applications, e.g., bottling, replenishing aquifers, ground and/or aquifer remediation, irrigation, etc.
Abstract:
Methods and systems for recovering, and processing ice obtained from an ice source, i.e., a glacier, ice sheet, ice cap, etc., are described herein. In particular, the ice obtained from the ice source holds unique properties and is processed as a beverage for consumption having unique properties. Further, the resulting product is produced with minimal human alteration and reduced energy input as compared to conventional methods for packaging water.
Abstract:
Apparatus for discharging effluent from a sea-based vessel (10) comprises a branched pipeline (22) which is disposed on the seabed (18). The vessel (10) carries a large-scale desalination plant (12), and the effluent, which is in the form of concentrated brine, is pumped through the branched pipeline (22) to a plurality of discharge locations on the seabed. The branched pipeline (22) includes a number of flexible discharge pipes (26a d) which fan out from a common location (30) towards open ends (28a-d). The open ends (28a d) are remote from each other, and the effluent is discharged simultaneously through the open ends (28a d) causing it to be dispersed effectively without harming surrounding eco-systems. In an alternative arrangement, a vessel-based water purification plant (10) is connected to a freshwater pipeline (16) and to a discharge pipeline (22), each of which is disposed on the seabed (18). Purified water is pumped to shore from the vessel (10) through the freshwater pipeline (16), and effluent is pumped from the vessel (10) into the sea (14) through the discharge pipeline (22).
Abstract:
A device for recovering drinking water from condensate consists of a self-supporting moulded part 11 consisting of a transparent synthetic resin such as PET or PC, which is resistant to UV radiation. The moulded part 11 presents an open bottom area 16 with a collecting channel 15 on the edge side, with the collecting channel 15 presenting an inner wall 18 oriented towards the circumferential surface 12 and serving, at the same time, as floating aid, and with the moulded part 11 being provided with a pouring opening in its upper section 13. For the manufacture of this device, a vacuum is created in a special deep-drawing tool not only in the region of the circumferential surface to be produced but also in the region of the collecting channel to be formed, and the moulded part is separated from a separated deep-drawing tool element outside the zone of the collecting channel.
Abstract:
A siphon jet is attached to a dry hydrant which is in communication with a body of water to increase the flow of fluid to the dry hydrant and assist in overcoming the effects of atmospheric pressure and gravity in drawing the water. A pressurized fluid source can add fluid to the siphon assembly and this forces water from the body up the hydrant pipe. Also, the fluid from the pressurized fluid source can be added forward of a valve to fill the hydrant pipe which thus minimizes the duration of priming operations.
Abstract:
A method and apparatus for eliminating zebra mussel colonizations from fresh water intake pipes for facilities, such as power plants and water treatment plants, are disclosed. One or more small diameter alternate intake pipes are disposed within a main intake pipe, and the pipes are connected by means of individually controllable valves to a pump for supplying water to the facility. Zebra mussel build up along the interior walls of any of the pipes is eliminated by shutting off flow in any mussel infested pipes with the valves, which causes starvation of the mussels due to suffocation. When water flow is resumed, the dead mussels are easily washed out of the pipes. The alternate intake pipes can be made of inexpensive flexible material, such as rubber, since they are not exposed to the environment external to the main intake pipe. In addition, a non-stick coating, such as silicone, can be disposed on the interior walls of the alternate pipes to further prevent mussel build up. A number of techniques for installing the one or more alternate pipes within an existing pipe are also disclosed.
Abstract:
A floating liquid intake for a liquid suction removal system, the liquid intake comprising housing defining an internal cavity. The housing has a hollow and buoyant annular body, an upper cover and a lower cover. The internal cavity is formed between the upper and lower covers. A substantially annular inlet is formed in the annular body for ingress of liquid into the cavity. The annular body has a buoyancy sufficient for the liquid intake to float in a liquid with the annular inlet submerged below the surface of the liquid in which the liquid intake is floating. A pipe extends into the cavity and the pipe includes an inlet that in use is open below the surface of the liquid within the cavity. The pipe extends outside of the cavity for connection to a liquid suction removal system.
