A method of recycling unused gases in a water aeration process includes providing a confined plunging liquid jet reactor system; producing a water jet at an outlet of a nozzle; entraining air in the water jet as the water jet flows from the outlet of the nozzle to obtain an entrained air water jet; entraining oxygen in the entrained air water jet to obtain an entrained oxygen air water jet; flowing the entrained oxygen air water jet into a water in a fluid reservoir thereby forming small water bubbles as the entrained oxygen air water jet penetrates into the water; forming large water bubbles as the small water bubbles ascend toward the surface layer of the water; and recycling unused gases under a hood by flowing the unused gases toward the outlet of the nozzle, thereby entraining the unused gases in the entrained air water jet.

Recycling of gas in confined plunging liquid jet reactor

A Confined Plunging Liquid Jet Reactor (CPLJR) is used for determining the effect of discharge of an effluent into seawater. A tank is provided and a plurality of water injectors supply sample effluents into the tank at multiple locations, using a pump to provide the supplied effluents. A water movement generator is used to simulate environmental movement of water in the tank, and soap bubble measurement meters/sensors are used to measure bubbles in the supplied effluents supplied by at least a subset of the water injectors, with respective ones of the bubble measurement sensors sensing bubbles associated with individual ones of the subset of water injectors. Dye injection and bubble sensors are used to observe and measure flow of injected effluent. A plurality of oxygen sensors are used for measuring oxygenation at different locations or levels in the tank.

Brine dispenser for brine dispensing experiments utilizing multi-plunging liquid jet reactors

A dispenser system includes at least one main tubular element, at least one nozzle, and openings formed on the main tubular element. The at least one nozzle receives and injects a first fluid inside the main tubular element. The openings in conjunction with the nozzle enable fluid circulation between inside and outside of the main tubular element.

The confined plunging liquid jet reactor with energy recovery includes a downcomer having an upper end, an open lower end, and a gas inlet for receiving gas, the downcomer extending into a liquid reservoir in a tank. A nozzle is mounted on the upper end of the downcomer for receiving a pressurized liquid to generate a liquid jet. The liquid jet impinges on liquid contained within the downcomer, creating turbulence and bubbles to entrain gas introduced through the gas inlet into the liquid reservoir as the jet travels downward in the downcomer. A riser is disposed around the downcomer and defines an annular air lift column. Unentrained gas and liquid exiting the downcomer rises in the air lift column with significant energy, the upper end of the riser being connected to a turbine coupled to a generator to recover energy from the air lift column.

The hybrid desalination and energy production system includes a desalination system for separating seawater into purified water and brine, an electrodialysis system for treating the brine and outputting low salinity water, a hypersaline brine solution, and Hgas; an evaporator for treating the hypersaline brine solution and outputting salt and water vapor; a superheater for treating the water vapor and outputting a superheated water vapor; a turbine for receiving the superheated water vapor to generate energy; a gas scrubber for receiving the Hgas from the electrodialysis system and producing dry hydrogen; and a hydrogen cell for receiving the dry hydrogen and outputting energy. A condenser converts the vapor into condensate and low salinity water. A desalinated water collection tank receives the desalinated or low salinity water. A pressure retarded osmosis system receives the brine, the low salinity water, and condensate from the condenser to produce dilute brine.

The apparatus for measuring disentrainment rate of air includes a Confined Plunging Liquid Jet Reactor (CPLJR) having a downcomer column surrounding a liquid jet. The end of the downcomer column is partially immersed in a receiving liquid pool contained in a reservoir. A conical ring is placed in the downcomer column below the liquid jet, the ring bearing against the wall of the downcomer column and forming a seal to define a headspace in the column. A gas supply and first bubble meter are connected to the column above the conical ring to supply gas and measure total entrainment. A second bubble meter connected to the headspace between the ring and the receiving pool measures disentrainment, and a third bubble meter connected to headspace above the receiving pool outside the column measures net entrainment.

Apparatus for measuring disentrainment rate of air

An aqueous solution flows through a desalination system that separates the aqueous solution into purified water and concentrated brine. The concentrated brine is directed into an electrodialysis system that includes an anode and a cathode and at least two monovalent selective ion exchange membranes between the anode and the cathode. At least one of the monovalent selective ion exchange membranes separates at least one diluate channel from at least one concentrate channel in the electrodialysis system, and this membrane selectively allows at least one monovalent ion to pass through the membrane while blocking or inhibiting the transport therethrough of multi-valent ions. The concentrated brine flows through at least the concentrate channel while a voltage is applied to the anode and cathode; and additional aqueous solution flows through the diluate channel.

Concentrating aqueous solutions via hybridizing electrodialysis and other desalination techniques

A water stream is passed between two juxtaposed similar ion exchange membranes (AEMs or CEMs), forming an ion depletion and ion enrichment zones when an electric field is applied. As cations are selectively transferred through the CEMs, for example, anions are relocated in order to achieve electro-neutrality, resulting in the concentration drop (increase) in ion depletion (enrichment) zone. Trifurcation of the output channel allows collection of concentrated, dilute and intermediate streams, with the intermediate stream serving as input to the next stage of a serialized implementation.

Purification of ultra-high saline and contaminated water by multi-stage ion concentration polarization (ICP) desalination

The method of recycling brine from a multi-stage flash desalination plant recycles the high-salinity, high-temperature brine output from a multi-stage flash desalination plant to produce diluted brine suitable for reinjection back into the multi-stage flash desalination plant as a makeup stream. The high-salinity, high-temperature brine output from the multi-stage flash desalination plant is diluted with water extracted from treated wastewater effluent output from a wastewater treatment plant, thus providing further recycling of the treated wastewater effluent. Following osmotic transfer of the diluting water from the treated wastewater effluent to produce the diluted brine, the remaining concentrated treated wastewater effluent passes through a secondary filtration system to yield a solid product and a volume of permeate water. The volume of permeate water may be further mixed with the diluted brine.

The mobile buoyant aerator has a buoyant toroidal capture tray for capturing contaminants and a large diameter tube extending downward through the center of the tray. The aerator may have air or other gas pumped down through a smaller concentric tube to exit at the bottom of the larger tube to entrain and carry contaminated water up the larger tube, capturing contaminants in the capture tray. Alternatively, the aerator may have a compressed gas tank at the bottom of the larger tube to preclude the need for a smaller diameter tube. In another alternative, the aerator has an air pump at the top of the structure to pump air down through the device. In a further alternative, the aerator has a water pump at the top of the structure that draws water from outside the aerator and pumps the water down through the center to entrain contaminated water.

The encapsulated fire extinguishing agents include a sealed outer shell containing at least one fire extinguishing agent therein. The shell is formed of material that melts when exposed to extreme heat, as in a fire. One embodiment has a single outer shell with a single fire retardant agent therein. Other embodiments may have a second shell within the outer shell, each shell defining an interior volume containing a separate fire extinguishing agent. The agents may combine to form a more effective fire extinguishing agent when the two shells melt. The shells may be formed to melt at different temperatures. Another embodiment includes an outer shell filled with a large number of smaller capsules, each of the smaller capsules filled with a fire extinguishing agent. The smaller capsules may each contain identical agents, or two or more different agents from one another.

Encapsulated fire extinguishing agents

The electrical outlet safety device is placed between an electrical plug and the corresponding electrical outlet or receptacle to which the plug is connected. The safety device includes a thin body portion formed of a material adapted to expand rapidly if exposed to a predetermined temperature. A series of thin, electrically and thermally conductive blades extends from the body, with the blades being captured between the prongs of the plug and the internal contacts of the receptacle when installed therewith. If excessively high electrical resistance and correspondingly high temperature are produced in one or more of the electrical connections between the plug and the outlet, the blades of the safety device transmit the excessive temperature to the body, whereupon the body is transformed to an expansive electrically insulating foam that expels the plug from the receptacle. Springs may be included within the body to provide additional expansive force.
