In chemistry, hydronium is the common name for the aqueous cation H3O+, the type of oxonium ion produced by protonation of water. It is the positive ion present when an Arrhenius acid is dissolved in water, as Arrhenius acid molecules in solution give up a proton (a positive hydrogen ion, H+) to the surrounding water molecules (H2O).

The invention discloses an efficient photochemical catalysis air purifier, which consists of a machine box, a filtering device, a fan and a photochemical reacting room. The photochemical reacting room includes a three-dimensional honey comb ceramic halftone which loads a photocatalyst of nano-composite TiO2 and an ultraviolet radiation light which irradiates towards the honey comb ceramic halftone. The photocatalyst is TiO2 adulterated with little iron, lanthanum or cerium hydronium, and the quantity of the added hydronium is 0. 005 percent to 0.5 percent of the total weight. The three-dimensional honeycomb ceramic net of a photocatalyst carrier is a honeycomb ceramic, which is provided with 100 to 600 holes per square inch. The polluted air follows a wind inlet fan to go through the filtering device which consists of a primary filtering net and an active carbon filtering net, and granular articles are removed and volatile organic matters with peculiar smell are absorbed; the gas after primary purifying goes into the photochemical reacting room which is provided with the ultraviolet radiation light, the photocatalyst of nano-composite TiO2 and the three-dimensional honey comb ceramic net, and under an effect of a strong oxidizer which is produced by the reaction of the ultraviolet radiation and the photocatalyst, various organic pollutants in the air can be effectively decomposed.

Method and device for reducing scale formation and/or corrosion in systems which conduct liquids
InactiveUS7273558B2Reduce foulingReduce corrosionSolid sorbent liquid separationWater/sewage treatment by ion-exchangePhosphatePotassium
The invention relates to a method and a device for reducing scale formation and / or corrosion in systems which conduct liquids or are in contact with liquids. According to the invention, this is achieved without reducing the quantity of hardness constituents contained in the liquid overall, without exchanging the hardness constituents in the liquid for other cations such as e.g. hydronium, sodium or potassium and without adding chemicals such as e.g. phosphates which inhibit scale formation to the liquid. Instead, scale formation is reduced by specifically shifting the molar distribution of the hardness constituents, especially the distribution proportions of the individual hardness constituents magnesium and calcium strontium and barium. According to the inventive method, proportions of the hardness constituents calcium, strontium and barium in the liquid are substituted with the proportions of the hardness constituent magnesium, In addition to efficiently reducing scale formation, the method inhibits corrosion processes in systems which conduct liquids or are in contact with liquids and reduces the extent of these processes.

The present invention relates to a method to wipe off magnesium hydronium and calcium hydronium by the moderate brine of salt field so as to improve sodium chloride output and quality in a sea salt production zone. When the brine of salt field reaches to 10 to 18 degrees Be', the magnesium hydronium is wiped off by electric lime waste residues. The amount ratio of the electric lime to the brine is 1 : 2.5 to 1 : 4. When the concentration of the electric lime reaches to 30 to 60 g / l, the pH value of the brine in the magnesium wiping off process keeps on 11 to 12.5. When the brine approaches to saturation, mirabilite and a few sodium carbonates are added in the brine to wipe off rest calcium hydronium. The invention leads the composition of beach field brine to generate qualitative change and reduces vaporizing impedance. The brine salt producing amount of unit volume and the potassium chloride content in the salt producing mother liquor have been improved greatly.
