Research on Phosphorus (P) removal capacity by blast furnace slags (BFS) has been undertaken in Sweden for the last decade. Both laboratory experiments and field trials have been carried out. While laboratory investigations revealed that BFS has a high Psorption capacity (95100%), P removal in field trials was much lower, ranging from 40 to 53%.

In the slag samples, the Ca concentration also decreased as a function of P addition, suggesting CaP precipitation as the major P removal mechanism for the slag. The Ca and PO 4 speciation data ruled out the formation of amorphous calcium phosphates and/or octacalcium phosphate as the major P removal mechanism.
