膜技术现在被广泛使用;特别是在家庭，海水淡化厂，制药应用等各种类型的过滤或反渗透，面对水污染，它们也被应用于消除水中出现的污染物。不完全的知识将膜的组成导向越来越致密的材料，这些材料与多孔成分相比具有更高的选择性。本文评估了众所周知的膜材料的优点和缺点，分离的颗粒大小的基础上，通常暴露于大量的水，与密集的疏水膜与目标运输新兴的污染物通过选择性屏障。此外，作者还介绍了几种采用第二类膜的膜工艺。
Membrane technologies are nowadays widely used; especially various types of filtration or reverse osmosis in households, desalination plants, pharmaceutical applications etc. Facing water pollution, they are also applied to eliminate emerging contaminants from water. Incomplete knowledge directs the composition of membranes towards more and more dense materials known for their higher selectivity compared to porous constituents. This paper evaluates advantages and disadvantages of well-known membrane materials that separate on the basis of particle size, usually exposed to a large amount of water, versus dense hydrophobic membranes with target transport of emerging contaminants through a selective barrier. In addition, the authors present several membrane processes employing the second type of membrane.
