Given that previous studies have neglected the potential mechanism of the difference in aluminum content affecting the activated sludge system, a research team from Wuhan University of Technology has investigated the morphology distributions of residual aluminum salts (RAS) and their effects on the removal efficiency of activated sludge (AS) under different PAC concentrations, and revealed the internal mechanisms of the effects of the excessive and appropriate concentrations of RAS on the AS system.
