Intracellular Polymer Dynamics in Enhanced Biological Phosphorus Removal Processes with Varying Organic Carbon Concentrations

Fabrizio Barnard

Enhanced biological phosphorus removal may degrade or fail during periods of low organic carbon influx. In normal cycles, anaerobic circumstances with excess organic carbons, and endogenous respiration Polyphosphateaccumulating organisms in EBPR were acclimated to both high and low organic carbon conditions, and then the dynamics of polymers conditions were investigated. After long-term acclimation, it was discovered that organic loading rates had no effect on PAO yield, and that the low organic carbon concentrations used were beneficial for PAO enrichment.

A low concentration of organic carbon in the influent produced a large synthesis of extracellular glucose. PAOs began to use polyphosphate considerably during both anaerobic and aerobic endogenous respiration when glycogen fell to approximately 80 10 mg C per gramme of volatile suspended solids. When the first-order reaction model was applied, glycogen had the highest degradation rate, followed by polyphosphate, while biomass decay had the lowest.
