(a) Time profile showing the incremental increase of influent phosphate (—) and influent acetate (- - - - ) during the startup period for the SBR using synthetic wastewater. The levels of phosphate contained in the effluent (○) are also given. (b) Time profile showing the incremental increase of influent phosphate (—) and influent acetate (- - - - ) during the startup period for the SBR using clarified effluent from a non-EBPR activated sludge plant. The levels of phosphate contained in the effluent (○) are also given. d, days.
