对膜分离过程进行建模并很好地预测过程变量可以减少中试规模实验中通常消耗的测试量、成本和时间。对于这些目的，数值模拟是非常方便的，因为它结合了快速，低成本和相对容易的实施。目前的工作包括开发一个预测的数值模型，从反渗透到纳滤的应用。该模型不使用经验关联式或实验传递系数：它只取决于溶液的物理性质，膜特性和操作条件。通过与科学出版物中的结果进行比较进行验证。
Modelling membrane separation processes and well predicting process variables can reduce the amount of tests, the costs and time usually consumed in pilot scale experiments. For these purposes, numerical simulation is very convenient as it combines rapidity, low cost and relatively easy implementation. The current work consists on developing a predictive numerical model for applications ranging from reverse osmosis to nanofiltration. The model does not use empirical correlations or experimental transfer coefficients: it depends only on solution physical properties, membrane characteristics and operating conditions. Validation is made by comparison to results found in scientific publications.
