An apparatus and system for managing the level of dissolved gases in water for aquatic life that provides sufficient water with sufficient oxygen saturation, without introducing excessive amounts of bubbles, and that can adequately degas or strip harmful dissolve gases from the water. The apparatus can generally comprise a storage compartment, a filter compartment, and a pump compartment. The filter compartment can be coupled with the storage compartment and comprise a filter element. The pump compartment can be coupled with the storage compartment and comprise a venturi air intake port, a degassing vent, a pump filter element, and a pump assembly. The pump assembly can comprise a venturi nozzle coupled with the venturi air intake port and a flow pump in fluid communication with a flow pump intake port. The pump filter element can at least partially encircle the flow pump intake port.

A dielectric assembly for generating ozone includes a positive electrode, a negative electrode, a dielectric for generating the ozone, and a knob adapted to extend outside of a housing into which the dielectric assembly is to be placed. A system is also provided for sanitizing and deodorizing water, food, surfaces and air including a microbiological reduction filter device having an input connected to a water supply, a venturi injector disposed within a housing and connected to an output of the microbiological reduction filter device which generates ozone and mixes the generated ozone with the water, and an electrode assembly comprising a plurality of electrodes, a dielectric for generating the ozone, and a knob extending outside of the housing. The dielectric in a first embodiment and the entire dielectric assembly in a second embodiment can be removed from the housing and replaced in its entirety by the knob.

Jet fuels' thermal oxidation characteristics are evaluated via the Standard Test Method for Thermal Stability of Aviation Turbine Fuels. This test method mimics the thermal stress conditions encountered by jet fuel in operation and is often carried out by laboratory devices, known as rigs. The rigs include a test section having a sleeve and a heater tube arranged therein. A pair of bus bars secure the test section to the rig and apply a current to the heater tube. The applied current heats the heater tube and subjects the sample jet fuels that are flowing in the volume between the sleeve and heater tube to high temperatures, which may produce thermal oxidation deposits on the heater tube. Heater tubes are difficult to install, however, and a gauge may be used to ensure accurate placement of the heater tube within the sleeve. In addition, the fuel sample must be prepared via an aeration process, and systems are disclosed for automating the aeration process such that the sample is prepared precisely according to the test standard. Moreover, the rig includes a pump system that moves the fuel sample through the test section, and a pump system is provided in a double syringe arrangement that optimizes fuel flow through the test section without fluctuation. Finally, the rigs include cooling systems for cooling the bus bars and maintaining an appropriate thermal profile within the heater tube, and cooling systems may be provided that independently control the temperature of each bus bar.

The present disclosure illustrates a hydrogen water generator, a micro/nano hydrogen bubble water generator and a micro/nano hydrogen bubble water production method. The hydrogen water generator of the present disclosure receives water and hydrogen gas, and five sections are formed inside the main body of the hydrogen water generator, so as to mix the hydrogen gas and the water to produce hydrogen water, without using a compressor to pressure the hydrogen gas. The water flows to a pressuring section via a liquid input section, and is pressured by a pressuring section and the pressured water further flows to a draining and mixing section to be mixed with the hydrogen gas. The water mixed with hydrogen gas flows to a decompressing section to be decompressed, and then passes a hydrogen water output section to output hydrogen water with micro/nano hydrogen bubbles.
