    摘要： A method for a cation-exchange resin wherein a strongly acidic cation-exchange resin is contacted with an aqueous eluting solution and the polystyrenesulfonic acid being eluted from this resin is measured, which comprises setting a plurality of molecular weight ranges in the molecular weight distribution of the polystyrenesulfonic acid eluted, and evaluating the performance capability of the cation-exchange resin based on the correspondence relationship of each molecular weight range with the amount eluted in said each molecular weight range. The evaluation method allows on-target and precise evaluation of the performance capability of a cation-exchange resin being independent of the structure of a base resin and the circumstance under which it is used, which leads to the determination of the optimum time for the exchange of a resin in a water treatment system using a cation-exchange resin, and thus to the extension of exchange of a resin and the reduction of an operation cost for the system.

    摘要： A specific monocarboxylic acid with even-numbered carbon atoms, sebacic acid, or a salt thereof is used as a corrosion inhibitor. Alternatively, a specific aliphatic monocarboxylic acid, sebacic acid, or a salt thereof is blended with a specific aliphatic oxycarboxylic acid, a specific polycarboxylic acid, or a salt thereof to prepare a corrosion inhibitor. These corrosion inhibitors can be used in a cooling water system using low-hardness water and in water systems wherein a water flow velocity above a given level cannot always be secured, whereby a high corrosion control performance can be exhibited without imposing unfriendly loads on the environment.

    摘要： Selenium-containing wastewater is sequentially treated through use of biological treatment means (6), chemical treatment means (12), and filtration means (14). In the biological treatment means (6), raw waste water (16) is subjected to anaerobic biological treatment so as to reduce selenate ions and/or selenite ions (soluble selenium) present in the raw waste water (16) to simple selenium, which is insoluble, to thereby remove the selenate ions and/or the selenite ions in the form of insoluble simple selenium. In the chemical treatment means (12), for example, a metal salt that reacts with soluble selenium to form an insoluble selenium compound is added to water treated by the biological treatment means (6), to thereby remove residual soluble selenium in the form of the insoluble selenium compound. In the filtration means (14), an insoluble substance remaining in water treated by the chemical treatment means (12) is removed through filtration. Thus, soluble selenium can be removed from the selenium-containing wastewater to a great extent without using a large amount of chemicals and without generating a large amount of sludge. Accordingly, a wastewater regulation limit of not greater than 0.1 mg Se/L can be cleared, and running cost and waste treatment cost can be reduced.
