Phosphate Removal From Wastewaters Using Fly-Ash Adsorption

Y�?¼cel Adig�?¼zel, Nuhi Demircioglu

In this research, removal of phosphorus in aqueous stream was investigated by using fly-ash obtained from Afsin-Elbistan thermal power plant station. The parameters such as initial phosphate concentration, adsorbent (fly ash) concentration, stirring speed and initial pH, temperature and electrolyte concentration were investigated. It was seen that phosphorus removal rate increased, increasing fly-ash concentration and stirring speed additionally it was observed that increasing the stirring speed shortened equilibrium time of adsorption process. An increase in the pH didn’t affect the adsorption yield. Finally, it was found that fly-ash could be used as a suitable adsorbent for the removal of phosphate from aqueous streams.
