Sealing Bag for Hydrogen Gas, and Method for Dissolving Hydrogen Gas

The present invention aims at dissolving hydrogen gas in a liquid and maintaining the solubility of the hydrogen gas in the liquid at a high state.A sealing bag 1 that dissolves hydrogen gas in a liquid by being put into the liquid includes a hydrogen permeable film that can permeate hydrogen gas that is sealed and filled in the sealing bag to outside. By sinking this sealing bag 1 into the liquid in advance, the hydrogen gas that is permeated through the hydrogen permeable film is dissolved in the liquid. Furthermore, since the hydrogen gas is continuously permeated little by little through the hydrogen permeable film, the solubility of the hydrogen in the liquid can be maintained at a high state.

Corrosion control composition for water treatment process

ActiveUS20140360943A1Maximize chain lengthHindering molecular structure stabilityWater treatment compoundsSpecific water treatment objectivesPipingChemistry
The present invention relates to a water treatment composition comprising blended phosphates which exhibit a synergistic effect for corrosion and scale control and as a sequestering chemical treatment of potable water and more particularly to chemistry which lowers the phosphate concentration necessary to achieve effective corrosion prevention. The composition controls corrosion and cleans the water distribution line by removing scale, tuberculation, and biofilm. Sequestration of the heavy metals and soft metals such as iron, manganese, calcium, and magnesium provides complete solubility of the material to be removed from the metal surface. The inclusion of citric acid with the blended phosphate formula improves drinking water quality in 2 ways: 1) a reducing agent reverses the oxidation of metals which would convert metal to metal salts (copper / lead, etc.) and 2) by chelation, it encapsulates transition metal cations, especially Manganese and Iron, found while source water passes through the treatment process and the drinking water distribution piping network.
