The setup of the hydraulic model structure of wastewater treatment plants (WWTPs) is an important step in the calibration of activated sludge models. The hydrodynamics of a full-scale municipal WWTP (Monterrey, Mexico) has been studied by means of the use of tracer tests and of a commercial simulator. A presimulation approach allowed the authors to quantify the appropriate rhodamine mass, set up a sampling plan, and evaluate the anticipated visual effect of the tracer test in the receiving river. The hydraulic behavior of the aeration tank for the first treatment line, a 7-cell plug-flow reactor, was shown to be best represented by 5 virtual mixed-tanks-in-series. The second treatment line, which included a vertical loop reactor (VLR), was best modeled as 3 tanks-in-series. The VLR, alone, was shown to be similar to a continuously stirred tank reactor, and not a circuit of tanks, as generally used to represent oxidation ditch reactors.
污水处理厂（WWTPs）水力模型结构的设置是活性污泥模型校准中的重要一步。通过示踪剂试验和商业模拟器，对一座全尺寸城市污水处理厂（墨西哥蒙特雷）的水动力特性进行了研究。预模拟方法使作者能够量化罗丹明的合适用量、制定采样计划，并评估示踪剂试验在受纳河流中预期的视觉效果。对于第一条处理线的曝气池（一个7格的推流反应器），其水力行为最好用5个虚拟串联混合槽来表示。第二条处理线包括一个垂直环流反应器（VLR），其最佳模型为3个串联槽。单独的VLR被证明类似于连续搅拌槽式反应器，而不是通常用于表示氧化沟反应器的槽式回路。
