本研究的目的是有效评估中试规模的膜工艺与中试规模的颗粒活性炭（GAC）和全尺寸的膜工艺 通过测定有效孔径分布（PSD）和 上述三个过程的有效分子量截止值（MWCO）。目前，饮用水处理工艺已得到改进 仅根据溶解有机碳（DOC）和紫外线吸收（UVA）对NOM去除进行评估。然而，很难做到这一点 确定通过特定处理过程去除NOM的哪部分（以分子量计）。因此 介绍了NOM去除过程中有效PSD的概念，并将其用于评价膜的效率 工艺，与GAC和凝固工艺相比。研究了膜的有效PSD和MWCO 根据饲料和处理过的样品中NOM的分子量分布，使用分数拒绝率确定 方法和特定MW下的相应斜率（Lee等人，2002）；通过这种方法，即使是GAC和 研究发现，混凝过程具有“有效的PSD和MWCO”，并且可以有效地与 膜过程。采用高效排阻色谱法（HPSEC）和紫外分光光度法测定了饲料和处理液的分子量分布 探测器在这项研究中，中试规模的纳滤/超滤膜和GAC（一种过滤器-吸附器型）工厂被全面建成 位于韩国昌原市的传统水处理厂。包括6个参考文献、表格、图表。

The objective of this study was to effectively evaluate pilot-scale membrane process versus pilot-scale granular activated carbon (GAC) and full-scale coagulation processes with respect to natural organic matter (NOM) removal, by determining an effective pore size distribution (PSD) and an effective molecular weight cutoff (MWCO) of the above-mentioned three processes. Currently, drinking water treatment processes have been evaluated in terms of NOM removal only with respect to dissolved organic carbon (DOC) and ultraviolet absorption (UVA). However, it is difficult to determine which portion of NOM (in terms of molecular weight) is removed by a specific treatment process. Thus, effective PSD concept for NOM removal process was introduced and used to evaluate the efficiency of membrane process, as compared to GAC and coagulation processes. Effective PSD and MWCO of a membrane were determined from MW distributions of NOM included in feed and treated samples, using the fractional rejection method and a corresponding slope at a certain MW, respectively (Lee et al, 2002); from this method, even GAC and coagulation processes were revealed to have "effective PSD and MWCO", and can be effectively compared to membrane processes. MW distributions of feed and treated solutions were measured by high performance size exclusion chromatography (HPSEC) method with UV detector. For this study, pilot-scale nanofiltration/ultrafiltration membrane and GAC (a filter- adsorber type) plants were set up in a full-scale conventional water treatment plant in the City of Changwon, Korea.
