膜污染是微咸水淡化和饮用水处理用膜装置高效运行的一个障碍。在原水中的污染物中，天然有机物（NOM）是造成膜污染的主要原因。本文报道了通过NOM系统地研究了钙浓度和流体动力学（由渗透通量和交叉流量控制）在纳滤（NF）膜污染中的作用。结果表明，污垢是由化学和水动力相互作用决定的。包括数字。

Membrane fouling is an obstacle for the efficient operation of membrane plantsused for the desalination of brackish water and drinking water treatment. Amongthe foulants in raw waters, natural organic matter ( NOM ) is a major cause ofmembrane fouling. A systematic bench-scale investigation on the roles of calciumconcentration and hydrodynamics (controlled by permeate flux and cross flow rate)in nanofiltration ( NF) membrane fouling by NOM is reported. It is shown that NOMfouling is determined by an interplay between chemical and hydrodynamicinteractions. Includes figures.
