Abstract

Two commercial nanofiltration membranes, NTR7410 (low salt rejection) and NTR7250 (medium salt rejection) were used for a basic experiment on the rejection of endocrine disrupters such as 17<i>β</i> estradiol, <i>p</i>-nonylphenol, bisphenol A and their complex solution. A nanofiltration membrane experiment was carried out under the operating condition of low transmembrane pressure of 0.5MPa. For the two nanofiltration membranes used, the rejection factor was high in the case, where pH adjustment of each feed solution was not performed. The <i>p</i>-nonylphenol rejection efficiency of NTR7410 was higher than that of NTR7250. On the basis of the former nanofiltration membrane experimental result, four commercial nanofiltration membranes, NTR7410, NTR7450 (medium salt rejection), NTR7250 and NTR729 (high salt rejection) were used for the rejection of endocrine disrupters contained in biologically treated sewage. The biologically treated sewage concentration of 0.039-0.055<i>μ</i>g·<i>l</i><sup>-1</sup> as 17<i>β</i> estradiol equivalent was reduced to the following concentration by each nanofiltration membrane: 0.026<i>μ</i>g·<i>l</i><sup>-1</sup> (NTR7410), 0.026<i>μ</i>g·<i>l</i><sup>-1</sup> (NTR7450), 0.003<i>μ</i>g·<i>l</i><sup>-1</sup> (NTR7250) and 0.009<i>μ</i>g·<i>l</i><sup>-1</sup> (NTR729). Rejection efficiency of endocrine disrupters from the biologically treated sewage increased in the order of NTR7250, NTR729, NTR7450 and NTR7410. Permeate flux of the nanofiltration membranes increased in the order of NTR7410, NTR7250, NTR7450 and NTR729.
