Excessive sewage sludge in terms of contained phosphorus speciation forms has been characterized. The analysis allowed identification of mobile forms of phosphorus in sewage sludge. Quantification of mobile forms of phosphorus is very important for its recovery directly from sewage sludge or for its application for natural purposes. Various phosphorus speciation methods have been presented. The results of the sewage sludge speciation conducted by means of two types of wastewater treatment (EvU-Perl technology and activated sludge) have been compared. The analysis covered the effect of such physiochemical factors as oxygenation, use of ultrasound and precipitation with iron chloride(III). It was concluded that changes in physiochemical conditions lead to alterations in the content of phosphorus speciation forms in sewage sludge.
