三个咨询团队为三个不同的污水处理厂进行了独立的建模项目，规模从大约113，800 m3/d（30 mgd）到530，000 m3/d（140 mgd），位于世界不同地区（美国和芬兰）。这些植物具有不同的处理目标，从硝化和部分反硝化（硝酸盐加亚硝酸盐<8.7 mg/L）到强化营养物去除（总氮<3 mg/L，总磷<0.3 mg/L）。在案例研究中应用了常用的模型，包括ASM 3（使用GPS-X模拟器）、New General（使用GPS-X）、Dold（使用BioWin）以及Dold模型甲醇降解能力的变体（GPS-X中的NGmeth）。作者比较和对比所采取的建模方法，包括校准和验证方法，敏感性分析，以及将结果应用于全面研究，设计和操作。尽管方法之间存在一些差异，但仍有许多相似之处，根据IWA活性污泥建模统一协议草案进行了讨论。作者还讨论了当前建模的局限性，并提出了改进最新技术水平的建议。
Three consulting teams conducted independent modelling projects for three different wastewater treatment plants ranging in size from approximately 113,800 m(3)/d (30 mgd) to 530,000 m(3)/d (140 mgd), in different parts of the world (USA and Finland). The plants have different treatment objectives ranging from nitrification and partial denitrification (nitrate plus nitrite <8.7 mg/L) to enhanced nutrient removal (total nitrogen <3 mg/L, total phosphorus <0.3 mg/L). Commonly-used models were applied in the case studies, including ASM3 (using the GPS-X simulator), New General (using GPS-X), Dold (using BioWin), and a variation of the Dold model methanol degradation capabilities (NGmeth within GPS-X). The authors compare and contrast the modelling approaches taken, including calibration and validation approaches, sensitivity analyses, and the application of results to full-scale studies, designs and operations. Despite several differences between the approaches, there are many similarities which are discussed in light of the IWA draft uniform protocol for activated sludge modelling. The authors also discuss current modelling limitations and offer suggestions to improve the state of the art.
