  • Patent number: 10252187
    Abstract: The ventilation pipe 60 having the openings at both the ceiling side and the bottom side is provided in the area where the rectification boards 50a to 50f are arranged, thereby nitrogen released from water (nitrogen released from water based on that gas dissolved in water is substituted by oxygen) can be moved to the ceiling side of the retainer body through the ventilation pipe 60. Thereby, nitrogen can be effectively exhausted from the exhaust opening 30a, thus it can be restrained that nitrogen is accumulated in the retainer body 10. Accordingly, it can be restrained that oxygen concentration (partial pressure) in the retainer body 10 decreases. Since oxygen quantity dissolved in water is increased, gas dissolved in water can be effectively substituted.

Additionally, the process of the present invention includes mechanisms that allow some of the by products generated by some of the reactions, to adsorb crystallization water and reduce the humidity of the mass without using external energy.

  • Patent number: 7704399
    Abstract: A system and method for the treatment of water for human consumption using a naturally occurring inorganic catalyst working within a pH range between 3 and 13, combining the inorganic catalyst at 3 parts per million to an oxidant, primarily hydrogen peroxide and a metal salt used as a coagulant and a primary catalyst, resulting in an efficient and economical phasic water purification and filtration system and process. The inorganic catalyst is a zeolite a synthetic zeolite or preferably chabazite.

  • Publication number: 20100072144
    Abstract: A method of treating a ballast water for sterilizing bacteria, microorganisms or organisms in the ballast water in a hold or ballast tank of a ship, has the steps of: sterilizing the bacteria, microorganisms or organisms by adjusting a residual chlorine concentration in the ballast water to 1 mass ppm or more and 1000 mass ppm or less with a hypochlorite, and removing the residual chlorine in the ballast water with a sulfite.

  • Patent number: 7611638
    Abstract: In a first treatment step part of at least one difficulty biodegradable or non-biodegradable organic compound is oxidized in polluted water by bringing said polluted water into contact with an ozone containing gas. The effluent is subsequently diluted with an aqueous liquid before a second treatment with ozone is carried out. If the concentration of the organic compound is still not sufficiently low, the treated effluent is diluted again and subjected to a further treatment with ozone. It was found that a more effective ozone treatment was obtained by the dilution or dilutions and that in particular no pH control was needed, so that no formation of additional salts occurred.

  • Patent number: 7582269
    Abstract: A subsurface thermally autogenous reactor and method has downgoing and upgoing flow passages connected at the bottom to form a U-tube and in heat exchange relation to each other. The downgoing and upgoing flow passages each have an upper heat exchange section and a lower reaction section. An air injection system injects air into the downgoing flow passage between the heat exchange and reaction sections. The cross sectional area of the upgoing heat exchange section is greater than the cross sectional area of the downgoing heat exchange section to balance the downgoing and upgoing flow velocities. The downgoing heat exchange section has multiple tubes to increase the heat transfer area.

  • Patent number: 7553424
    Abstract: In controlling a sterile water production device, if pH of sterile water is smaller than a preset pH, an additional aqueous hypochlorite solution is injected into the sterile water to increase the pH back to the preset pH, and a molar quantity of residual alkaline impurities present in such additional aqueous hypochlorite solution is determined. Next, a predetermined amount of further additional aqueous hypochlorite solution is injected into the sterile water, wherein such predetermined amount is an amount required to yield additional content of hypochlorous acid in a resulting sterile water, to such a degree that a molar quantity of that hypochlorous acid is equal to the foregoing determined molar quantity of residual alkaline impurities. After such injection, pH of sterile water yielded is increased, and an acid aqueous solution is then injected into the sterile water to thereby decrease the increased pH back to the preset pH.

  • Patent number: 7540966
    Abstract: The invention relates to a method for purifying water by dissolving one or more soluble metal salts in the water to provide corresponding metal ions, by dissolving hypohalite into the water, and by regulating the residence time, and thus hypohalite concentration in the device using a venturi nozzle disposed between the metal generator and the hypohalite generator.
