3.2. Phase 2: Validation
During the validation phase (Phase 2), 32% of the applied control actions (Table 2) corresponded to moderate or low reductions in the air scour flow rate (case 1, case 2 with ST ≥ LT, case 3 with ST < LT and case 4), whereas 43% of the control actions corresponded to high reductions in the air scour flow rate (case 3 with ST ≥ LT), and the air scour flow rate was incremented by the control system in 25% of the cases (case 2 with ST < LT).
