Comparison of the Fundamental Properties and Water Purification Function between Clinker Ash and Carbonized Materials

Abstract

A comparison of the fundamental properties and water purification functions of clinker ash and carbonized materials were examined in this study. Because both of the EC values of clinker ash before and after washing were smaller than those of charcoals, the electrolyte elution from clinker ash was assumed to be small in water immersion. Next, the original powder and an average 0.5mm fraction of clinker ash were functioned well as a filter material for mud suspension, and remarkable reductions in the turbidity and COD value were recognized. In addition, from the measured results of inorganic nitrogen and phosphorus concentrations, the water purification ability of clinker ash was assumed to be almost the same as those of charcoals. In this case, the liquation of phosphorus was not observed in clinker ash unlike the charcoals.
