所有样品都出现结垢；因此在这个过程中需要改进。然而，与最初未稀释的样品 C2 和 C4 相比，样品 C1 和 C3 的结垢率较低。在 20 °C 的初始稀释下进行的测试中实现了较低的结垢率。通过膜系统的每个样品的污染系数如表 3 所示。

All of the samples presented occurrences of fouling; therefore improvements are necessary in the process. However, samples C1 and C3 presented lower fouling rates compared with samples C2 and C4, which initially were not diluted. Lower fouling rates were achieved in tests at 20 °C with initial dilution. The fouling coefficient for each sample passed on membrane system are showed in Table 3.<br>
