  • Patent number: 8476481
    Abstract: A method for treating a radioactive liquid waste containing a sodium salt, which includes: feeding a radioactive liquid waste containing at least one of sodium hydroxide, sodium hydrogencarbonate and sodium carbonate to an anode chamber in an electrolytic cell provided with an anode and a cathode on both sides of a permeable membrane, which is selectively permeable to sodium ions, and electrodialyzing the radioactive liquid waste; separating sodium ions permeated through the permeable membrane as sodium hydroxide from the radioactive liquid waste in a cathode chamber; separating a radioactive substance remaining in the anode chamber as a concentrated radioactive liquid waste; and recovering the separated sodium hydroxide and concentrated radioactive liquid waste, respectively.

  • Publication number: 20120244602
    Abstract: A method for culturing cells or microorganisms by dissolving oxygen or carbon dioxide in a culture solution containing a nutrient including: supplying gas containing oxygen or carbon dioxide into inside of a glass porous body being configured to have cylindrical shape and a large number of uniformly fine pores in the outer surface and being configured to seal the end of the glass porous body; generating bubbles that have a 50% diameter of 200 ?m or less in a volume-based particle size distribution from the outer surface of the porous body by using gas containing oxygen or carbon dioxide that is supplied from an unsealed end of the glass porous body; suppressing aggregation of the bubbles by at least one of a cell-protecting agent for protecting the cells and a protein hydrolysate included in the culture solution; and dissolving oxygen or carbon dioxide in the culture solution.

  • Publication number: 20120022312
    Abstract: A method for treating a radioactive liquid waste containing a sodium salt is described, including: a liquid waste reducing step of partially reducing sodium nitrate contained in a radioactive liquid waste to convert the radioactive liquid waste into a reduced solution containing at least one of sodium hydroxide, sodium hydrogencarbonate, and sodium carbonate; and an electrodialysis step of performing electrodialysis of the reduced solution by supplying the reduced solution to an anode chamber of an electrolytic cell, the electrolytic cell including an anode and a cathode disposed on both sides of a permeable membrane which a sodium ion selectively permeates.
