Corrigendum to “Start-Up Characteristics of a Granule-Based Anammox UASB Reactor Seeded with Anaerobic Granular Sludge”

In the article titled “Start-Up Characteristics of a Granule-Based Anammox UASB Reactor Seeded with Anaerobic Granular Sludge” [1], there were two errors in Figure 2, where NH₃⁺ in the legend of Figure 2(a) should be changed to NH₄⁺ and the x-axis in Figure 2(e) should be changed from “pH” to “Ratio.” The corrected figure is as follows.

Figure 2.
