The process of simultaneous precipitation of phosphorus from synthetic wastewater in aerobic biological systems with Fe(II) and Al(III) salts has been studied. Respirometric measurements have been applied to rvaluate the influence of heavy metals on activated sludge respiration activity. The factors which influence the evaluation of inhibition or stimulation effect of precipitants on biomass have been studied. The stimulation effect of Fe on heterotrophic biomass respiration activity was observed in typical metal concentrations range applied in the chemical process of phosphorous removal. The influence of precipitants on biokinetic parameter values has been investigated. Not only phosphorus elimination and the increase of activated sludge activity, but also the improvement of sludge settlement characteristics and improved efficiency of organic impurities removal resulted from the work.
