Decoupling EPS-bound and intracellular phosphorus in waste activated sludge: A low-disturbance strategy for controlled recovery
TSS of phosphorus with only 13.2% cell apoptosis, comparable to alkaline extraction yet with minimal biological disruption. Confocal microscopic analysis confirmed that the released phosphorus predominantly originated from the EPS matrix, indicating that the hybrid treatment effectively targeted EPS-P while preventing intracellular release. These findings establish a non-destructive extraction pathway based on the coupling of physical cavitation and selective chelation, providing mechanistic insight into EPS-mediated P binding and offering a new strategy for controlled, high-efficiency phosphorus recovery from sludge.
