已经开发出非常适合工程应用的数学模型来预测集成连续流PAC吸附/淹没膜过滤过程对水中痕量有机物的去除。这些模型是基于单溶质均匀表面扩散模型（HSDM）和连续和初始（批量）PAC给药模式的质量平衡方程。这些模型考虑了膜和表面对吸附动力学的限制。以雌酮为模型有机化合物，通过连续流PAC吸附/膜过滤实验验证了所建立的模型。结果表明，开发的模型提供了合理的表征痕量雌酮去除的过程。
Mathematical models that are well suited to engineering application have been developed to predict the removal of trace organics from water by integrated continuous flow PAC adsorption/submerged membrane filtration processes. These models are based on the single solute homogeneous surface diffusion model (HSDM) and mass balance equations for both continuous and initial (batch) PAC dosing modes. Both film and surface limitation to adsorption kinetics have been considered in these models. The developed models have been verified through continuous flow PAC adsorption/membrane filtration experiments using estrone as the model organic compound. The results indicated that the developed models provide reasonable representations of the trace estrone removal by the processes examined.
