本研究的主要目的包括:更好地理解 NOM污染的化学（如天然有机物[NOM]类型）和物理（如渗透通量）方面；评估NOM污垢的水力可逆性；并且，探索潜在的方法 污垢控制。为了解释这些目标，自然水域被预先确定为 以具有代表性的NOM为主，对几种商用低压中空纤维进行了挑战 （LPHF）膜在良好控制的实验条件下。讨论的材料和方法包括:天然水样；低压中空纤维膜；小型过滤装置；过滤协议； 尺寸排除色谱仪（SEC）。讨论结果包括:NOM和膜类型对总污染的影响；渗透通量对污垢的影响；NOM类型对水力不可逆污垢的影响；反洗流量对水力不可逆污垢的影响；化学不可逆污垢；以及，SEC对NOM的定性。包括6个参考文献、表格、图表。

The primary objectives of this study included: provide a better understanding of the chemical (e.g., natural organic matter [NOM] types) and physical (e.g., permeate flux) aspects of NOM fouling; evaluate the hydraulic reversibility of NOM fouling; and, explore the potential methods of fouling control. In order to interpret these objectives, natural waters predetermined to be dominated by representative types of NOM were employed to challenge several commercial low pressure hollow fiber (LPHF) membranes under well-controlled experimental conditions. The materials and methods discussion includes: natural water samples; low pressure, hollow fiber membranes; bench scale filtration unit; filtration protocol; and, size exclusion chromatograph (SEC). The results discussion included: effects of NOM and membrane type on total fouling; effects of permeate flux on fouling; effect of NOM type on hydraulically irreversible fouling; effects of backwashing flux on hydraulically irreversible fouling; chemically irreversible fouling; and, SEC characterization of NOM. Includes 6 references, tables, figures.
