0123281码头拟议的研究的目的是发展的孔堵塞和溶质置换机制的竞争性吸附微量有机化合物粉末活性炭（PAC）的基本认识。 这些信息将被用来开发这些影响，将被纳入混合吸附膜过程的数学模型方程。 将使用模型化合物或探针以及天然有机物进行吸附研究。 在多孔吸附剂中的竞争效应将被建模为PAC/膜系统使用的探针数据第一。 在使用探针验证模型后，将测试模型的一般形式对NOM/痕量化合物竞争吸附的适用性。 本研究的结果可用于制定建议，为全规模的混合吸附膜工艺去除水中微量有机化合物的优化设计和操作。***

0123281 Marinas The objective of the proposed research is to develop a fundamental understanding of the pore blockage and solute displacement mechanisms of competitive adsorption of trace organic compounds on powdered activated carbon (PAC). This information will be used to develop equations for these effects that will be incorporated into mathematical models of hybrid sorption-membrane processes. Adsorption studies will be conducted using model compounds or probes, as well as with natural organic matter (NOM). The competitive effects in porous adsorbents will be modeled for the PAC/membrane system using the probe data first. After the model has been verified using probes, the general form of the model will be tested for applicability to NOM/trace compound competitive adsorption. The results of this research could be used to develop recommendations for the optimum design and operation of full-scale hybrid sorption-membrane processes for the removal of trace organic compounds from water. ***
