  • Method for producing pure water
    Patent number: 5554295
    Abstract: A method for producing pure water is provided which reduces non-ionic silica in pure or ultrapure water. With the method, non-ionic silica which is contained in water is brought into contact with ozone having a concentration of at least 1 ppm for at least 20 minutes to react therewith and, simultaneously with or after this reaction process, irradiated with ultraviolet rays to undergo ionization and passed through an anion exchange column. The processed water passed through this ion exchange resin column contains practically no non-ionic silica.

  • Apparatus for producing pure water
    Patent number: 5470461
    Abstract: An apparatus for producing pure water is provided which includes means for ionizing non-ionic silica which is contained in water comprising a vessel for allowing the water to pass therethrough and stay therein for predetermined lengths of time; means for dissolving ozone in the water in this vessel; means for irradiating the water in which ozone has been dissolved with ultraviolet rays; means for separating gases from liquids located between the means for dissolving ozone and the means for irradiating water; and means for fixing ionized silica in the water to a solid electrolyte by ion exchange.

  • Aeration apparatus for producing ultrapure water
    Patent number: 5380471
    Abstract: In an aeration apparatus and method for producing ultrapure water, a device for vigorously mixing an aeration gas with untreated water is attached to a water pipe through which the water is fed to a reaction tank. The device vigorously mixes the aeration gas with the untreated water in the water pipe before the water reaches the reaction tank. The reaction tank can be smaller, an aeration system for producing ultrapure water can be simpler, and the efficiency of the aeration system can be improved.

  • Method for concentrating .beta.-lactam antibiotic solution
    Patent number: 4455306
    Abstract: The present invention relates to a method for concentrating a dilute aqueous solution of a .beta.-lactam antibiotic which is readily susceptible to heat, by subjecting a dilute aqueous solution of a .beta.-lactam antibiotic, said solution containing 2 to 20% (v/v) of a lower alcohol, to concentration by means of a permeable membrane made of poly(ether/amide) or polybenzimidazolone.
