Abstract

A batch-type study was conducted to investigate the phosphorus release and uptake under anaerobic and aerobic conditions according to organic loading changes. As organic loading increased, anaerobic P release increased but aerobic P uptake decreased. Where organic carbon contents remain high in aerobic conditions, PHB consumption within the microbial cells diminished, therefore it was found that in order to enhance P uptake rate, it should reach the endogenous growth stage where the entire organic loading was consumed.
