膜蒸馏（MD）是一种相对较新的工艺，作为蒸馏和反渗透（RO）等分离工艺的低成本、节能替代品正在进行研究。MD非常适合去除挥发性有机化合物（VOCs），可能是生产饮用水的相对经济和环境友好的工具。在MD工艺中，加热的给水溶液与疏水微孔膜接触。膜的疏水性防止水溶液渗透到孔隙中，从而形成液体- 每个孔入口的蒸汽界面和蒸汽到膜渗透侧的对流通量。可采用多种方法在膜上施加蒸汽压差，并驱动膜上的传质。其中，真空膜蒸馏（VMD）被认为是从水溶液中去除和分离挥发性有机物和溶解气体的合适配置。本研究调查了在饲料溶液中存在有机物的情况下，使用VMD去除消毒副产物的混合物。与之前的研究不同，该研究使用的是超纯水和单一VOC的二元溶液，该研究使用的是自然产生的消毒副产物及其前体，其浓度与传统地表水处理设施中的典型浓度相同。 包括9个参考文献、图表。

Membrane distillation (MD) is a relatively new process that is being investigatedas a low cost, energy saving alternative to separation processes such as distillation and reverse osmosis (RO). MD is well suited for the removal of volatile organic compounds (VOCs) and may be a relatively economic and environmentally friendly tool to produce potable drinking water. In the MD process, a heated aqueous feed solution is brought into contact with a hydrophobic microporous membrane. The hydrophobic natureof the membrane prevents penetration of the aqueous solution into the pores, resulting in a liquid-vapor interface at each pore entrance and convective flux of vapors to the permeate side of the membrane. A variety of methods may be employed to impose a vapor pressure difference across the membrane and drive mass transfer across the membrane. One of these, vacuum membrane distillation (VMD) is considered a suitable configuration for the removal and separation of VOCs and dissolved gases from aqueous solutions. This study investigated the use of VMD to remove a mixture of disinfection byproducts in the presence of organic matter in the feed solution. Unlike previous investigations, which used binary solutions ofultrapure water and a single VOC, this research used naturally occurring disinfection byproducts and their precursors at concentrations typical of those found in a conventional surface water treatment facility.
