反渗透应用的盈利能力已经通过使用基于实验数据的众所周知的经济模型进行了评估，其中额外的运营成本被认为是更现实的估计。包括一个计算模板，以提供对特定膜装置的初步经济评估的简单访问。该模型的响应与一个真实的反渗透应用程序进行了检查，因为这是从乳品超高温工厂的冷凝液回收。进行了灵敏度分析，以显示模型的行为时，受到一些工艺参数波动。基本情况下，它认为设计流量为20立方米/小时，产生了3.3年的投资回收期，是一个具有成本效益的设施摊销期研究。回收率被证明是一个相关的参数的影响，在经济可行性的过程中，增加20%的净现值估计产生了48.6%的改善。
The profitability of a reverse osmosis application has been evaluated by using a well-known economic model based on experimental data, where additional operating costs were considered to represent a more realistic estimation. A calculation template was included to provide an easy-access to a preliminary economic evaluation of a specific membrane installation. The response of the model was checked with a real reverse osmosis application as this is the condensate recovery from a dairy ultra-high-temperature plant. A sensitivity analysis was performed to show the model behaviour when subjected to some process parameter fluctuations. The base case, which considers a design flow of 20 m3/h, produced a payback period of 3.3 years, being a cost-effective facility for the amortization period studied. The recovery rate proved to be a relevant parameter of influence in the economic viability of the process, as an increase of 20% produced an improvement of 48.6% in the net present value estimated.
