Description
この複合半透膜を、M. タニグチ（Ｍ．Ｔａｎｉｇｕｃｈｉ）らによるジャーナル・オブ・メンブレン・サイエンス（Ｊｏｕｒｎａｌ ｏｆ Ｍｅｍｂｒａｎｅ Ｓｃｉｅｎｃｅ），第１８３巻，２０００年，ｐ２５９−２６７に示される平膜セルを用いて、供給圧力５．５ＭＰａ、２５℃、ｐＨ７．０、全溶質濃度３．５重量％の模擬海水（ホウ素濃度５．０ｍｇ／ｌ）を用いて流量３．５ｌ／分で評価したところ、膜透過流束は０．６７ｍ３／ｍ２・日、透過水ＴＤＳ濃度は６３ｐｐｍ、透過水ホウ素濃度は０．２８ｍｇ／ｌであった。この複合半透膜の純水透過係数Ｌｐ＝３．６９×１０−１２ｍ３／ｍ２・Ｐａ・ｓ、ホウ素透過係数Ｐｂ＝３６８×１０−９ｍ／ｓであり、純水透過係数が大きく、ホウ素透過係数が小さい海水淡水化に適した半透膜となった（この膜をＵＴＣ−Ａという）。 This composite semipermeable membrane is formed using a flat membrane cell shown in Journal of Membrane Science, Vol. 183, 2000, p259-267 by M. Taniguchi et al. Evaluation was made at a flow rate of 3.5 l / min using simulated seawater (boron concentration 5.0 mg / l) having a supply pressure of 5.5 MPa, 25 ° C., pH 7.0, and a total solute concentration of 3.5% by weight. The permeation flux was 0.67 m 3 / m 2 · day, the permeate TDS concentration was 63 ppm, and the permeate boron concentration was 0.28 mg / l. The composite semipermeable membrane has a pure water permeability coefficient Lp = 3.69 × 10 −12 m 3 / m 2 · Pa · s, a boron permeability coefficient Pb = 368 × 10 −9 m / s, and the pure water permeability coefficient is It became a semipermeable membrane suitable for seawater desalination having a large boron permeability coefficient (this membrane is referred to as UTC-A).
また、東レ（株）製ＳＵ−８１０膜エレメントに使用されている平膜を同様に評価した。この複合半透膜の純水透過係数Ｌｐ＝４．０２×１０−１２ｍ３／ｍ２・Ｐａ・ｓ、ホウ素透過係数Ｐｂ＝５４３×１０−９ｍ／ｓとなり、ＵＴＣ−Ａに比べて、純水透過係数、ホウ素透過係数ともに大きな値を得た。 Moreover, the flat membrane used for Toray Co., Ltd. product SU-810 membrane element was evaluated similarly . This composite semipermeable membrane has a pure water permeability coefficient Lp = 4.02 × 10 −12 m 3 / m 2 · Pa · s and a boron permeability coefficient Pb = 543 × 10 −9 m / s, which is higher than that of UTC-A. In addition, large values were obtained for both the pure water permeability coefficient and the boron permeability coefficient.
