Abstract:
A portable water conditioning system is provided that includes an incoming water inlet; a reverse osmosis stage in fluid communication with the incoming water inlet, the reverse osmosis stage having a permeate outlet and a concentrate outlet; a diversion device having a diversion valve, the diversion valve placing the concentrate outlet in fluid communication with a waste water outlet; a deionizing stage in fluid communication with a pure water outlet; a bypass valve configured to selectively place the permeate outlet in fluid communication with one or more of the waste water outlet, the deionizing stage, and the pure water outlet; and a controller configured to control the diversion device and the bypass valve to provide water at the pure water outlet of a desired condition.
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:
A mobile marine barrier (1) comprising a base (2) and a hood (8) located at a distal end thereof is described. The hood (6) comprises a funnel (15) and a distal surface (18) located therein which allows the hood (6) to morph its shape, size and strength so as to give adaptable coastal protection against naturally occurring events. This is achieved by incorporating a telescopic funnel such that the length of the hood (6) and thus the area of its open end can be altered so as to vary the quantity of water directed towards the distal surface (18). The hood (16) may also comprise a mobile face (17) that forms part of variable volume chamber (26) located within the hood (8) which can be filled and emptied with fluids.
Abstract:
A mobile HEB and TEP mitigation device includes a mobile body capable of movement within or upon a body of water. Located within the mobile body is a hydrodynamic separation system which includes a water inlet, a hydrodynamic separation unit and a collection tank. The hydrodynamic separation unit includes two outputs, one for a clean stream output line containing clean water and arranged to re-circulate the clean water, and another for a concentrate stream output line, the concentrate stream output line configured to place concentrated water containing potentially harmful bio-organic materials into the collection tank. Also included on the mobile body is a power source and an engine/steering unit, wherein the steering portion of the engine/steering unit provides a capacity to move the mobile body in an intended direction. The mitigation device may also be used as an embedded part of an on-shore arrangement.
Abstract:
Acoustic pressure shock waves are applied to a membrane in a fluid to prevent attachment of or dislodge biological or solid matter for membrane cleaning or desalination with a membrane.
Abstract:
A method of desalinating water through application of acoustic pressure shock waves to a slush to separate ice crystals from brine and recovering desalinated water from the separated ice crystals.
Abstract:
A floatable, portable and readily deployable apparatus used in a surface water body for the collection, mixing, separation, containment and removal of total solids from fluid in surface water by settling, sorption, floatation or filtration of total solids from fluid entering or pumped into the apparatus. Separation of total solids from fluid can include the use and recycling of commercially available or proprietary biologic, chemical and/or physical substances and processes to increase the rate and percentage of total solids removed from fluid in the apparatus.
Abstract:
A method of operating a wastewater vaporization system includes providing wastewater to a flow head at a regulated rate, and operating the flow head to atomize the wastewater into droplets of a calculated size. The calculated size is based on measured environmental conditions.
Abstract:
Embodiments described herein generally relate to humidification-dehumidification desalination systems, including apparatuses that include a vessel comprising a humidification region (e.g., a bubble column humidification region) and a dehumidification region (e.g., a bubble column dehumidification region), mobile humidification-dehumidification (HDH) desalination systems (e.g., systems having a relatively low height and/or a relatively small footprint), and associated systems and methods. Certain embodiments generally relate to methods of operating, controlling, and/or cleaning desalination systems comprising a plurality of desalination units (e.g., HDH desalination units).
Abstract:
Provided is an apparatus for separating and collecting oil spilled in an ocean, which is capable of easily removing the oil spilled in rivers, reservoirs, or oceans using a density difference between water and oil. The apparatus for separating and collecting oil spilled in the ocean according to the present invention includes a separator body having a separation space therein formed to receive mixed water in which water and oil are mixed, and a mixed water introducing part formed at one side thereof to introduce the mixed water, a drainage member which is installed in the separation space, and in which an end thereof is connected and in communication with the separator body to be located lower than a level of the water, such that the water separated from the oil due to a density difference is discharged to an outer side of the separator body, and a length adjusting part configured to move a height of an upper end of the drainage member exposed to the outer side of the separator body vertically to control the level of the water in the separator body.
