No items found.

A method and system for removing phosphorus, organic carbon and nitrogen using aerobic granular biomass and pulsed aeration. The present invention relates to a method and system for enhancing the growth of biopolymer-accumulating organisms in order to remove phosphorus, organic carbon and nitrogen from industrial or urban wastewater using aerobic granular biomass and pulsed aeration. The system and method use a sequential batch reactor (SBR) with anaerobic feed/reaction or with unreacted feed. The pulsed aeration has a frequency of a few seconds.
