摘要： Die Erfindung betrifft ein Verfahren zur Reduzierung des Sauerstoffgehaltes des Heizungswassers einer Heizungsanlage. Dabei ist es vorgesehen, dass das Heizungswasser im Zirkulationsbetrieb durch einen ein Reduktionsmittel enthaltenden Kationenaustauscher, vorzugsweise einen stark sauren Kationenaustauscher oder ein Gemisch aus einem schwach sauren und einem stark sauren Kationenaustauscher, und/oder durch einen ein Reduktionsmittel enthaltenden Anionenaustauscher, vorzugsweise einen stark basischen Anionenaustauscher, geleitet wird und dass der in dem Heizungswasser enthaltene Sauerstoff beim zirkulierenden Durchfluss des Heizungswassers durch den Kationenaustauscher und/oder den Anionenaustauscher durch Reaktion mit dem Reduktionsmittel zumindest anteilig aus dem Heizungswasser entfernt wird.
Die Erfindung betrifft auch eine Vorrichtung zur Durchführung des Verfahrens.
Das Verfahren und die Vorrichtung ermöglichen die effiziente Entfernung von Sauerstoff aus in einer Heizungsanlage geführtem Heizungswasser.

摘要： To provide a ballast water treatment apparatus that can eliminate the possibility that the sterilizing agent supply device, and the like, may be adversely affected by the reduction reaction heat that is generated in the detoxication of the sterilizing agent residue. The ballast water treatment apparatus includes a sterilizing agent supply device (20) that supplies a chlorine-based sterilizing agent into the inside of a ballast water piping (3) through which ballast water is passed toward a ballast tank (2); a reduction agent supply device (30) that supplies a reduction agent that is reacted with the chlorine-based sterilizing agent into the inside of the ballast water piping (3); a first piping (22) that transfers the chlorine-based sterilizing agent that has remained in the sterilizing agent supply device (20) into the inside of the ballast water piping (3); a second piping (32) that transfers the reduction agent into the inside of the ballast water piping (3); and an injection part (7) that injects the chlorine-based sterilizing agent transferred from the first piping (22) into the inside of the ballast water piping, the second piping (32) being connected to the injection part(7), and the chlorine-based sterilizing agent that has remained in the sterilizing agent supply device (20) being injected into the inside of the ballast water piping (3) together with the reduction agent from an opening part (7a) that is provided for the injection part (7).

摘要： Provided are a water quality purification device, a water purifier and an aquarium that use the water quality purification device. The water quality purification device includes a component filled with a micro-electrolysis catalyst (1) and a biological filtration component (2) that are connected in series. By utilizing a micro-electrolysis technology, pollutants in water are pre-processed and the biodegradability of the water is improved. A water body processed by the micro-electrolysis catalyst (1) enters the biological filtration component (2), which can greatly improve the purification efficiency of the biological filter bed. Working together with an adsorption electrode (4), this structure can effectively stabilize the water quality in the aquarium and greatly reduce the required times of changing water.

摘要： A water injection process plant includes a catalytic deoxygenation unit located subsea that makes use of a reducing agent sent from topsides in liquid form. The catalyst is preferably a palladium catalyst or its equivalent. The reducing agent is an oxygen scavenger such as but not limited to hydrazine, carbohydrazide, sodium erythorbate, methyl ethyl ketoxime (“MEKO”), hydroquinone, diethylhydroxylamine (“DEHA”), formic acid (methanoic acid). A chemical umbilical can be used to deliver the reducing agent to a mixer located upstream of the deoxygenation unit, where the agent is mixed with seawater containing oxygen.

摘要： The invention provides methods and compositions for the protection of a membrane from both biofouling and from damage caused by a biocide. The invention utilizes PAA as both a biocide and as a reducing agent for other oxidizing biocides. This is especially beneficial because without the invention one would be forced to choose between preventing membrane biofouling or preventing membrane damage from oxidizing biocides.

摘要： Methods for reducing and regulating the acidification of water are provided. The method for reducing the acidification of water includes contacting at least one melanin material with the water and catalyzing a reaction between the water, CO2 and/or bicarbonate that produces glucose and increases pH of the water. The acidification of water is regulated by removing the at least one melanin material from the water once a desired pH of the water has been attained. The methods for reducing and regulating the acidification of water are particularly suited for the treatment of seawater that has been acidified by naturally occurring or artificially initiated reactions that increase free hydrogen ions in water, for example absorption of atmospheric carbon dioxide.

摘要： A system for treatment of a polluted effluent, includes an outer chamber configured to treat the polluted effluent in mixture with a purification slurry including particles of one or more catalysts and/or organoclays, or a mixture thereof. The outer chamber includes (i) a stirring unit consisting of an engine and a stirrer, configured to mix the polluted effluent and the purification slurry to prevent the particles from sinking without causing a turbulence, (ii) a membrane located at the top of the outer chamber through which a treated effluent passes, while preventing the particles of one or more catalysts and/or organoclays from exiting the outer chamber together with the treated effluent, (iii) a membrane cleaning system configured to remove and collect the particles of one or more catalysts and/or organoclays accumulated on the membrane, and re-introducing the particles back to the bottom of the outer chamber.
