6.1.3.6. Phosphate removal
Phosphorus is released from bacterial biomass in the anaerobic stage and is assimilated by these bacteria in excess as polyphosphate (Poly P) during the aerobic stage.
In the aquaculture systems, stable ortho phosphate concentrations were found throughout the culture period. Phosphorus immobilization took place in the anoxic treatment stages of the system where it accumulated to up to 19 % of the sludge dry weight.
