ABSTRACT

This study evaluates the efficacy of titanium tetrachloride (TiCl₄) on phosphorus (P) removal in synthetic wastewater. Jar test experiments were performed at various TiCl₄ concentration (0.25-0.59 mM), and intensities of slow (30-60 rpm) and rapid (100-250 rpm) mixings to determine the conditions at which P removal was most efficient. The P-removal efficiency was highest (about 99%) at TiCl₄ concentration ([TiCl₄])=0.39 mM with rapid-mixing intensity=100 rpm and slow-mixing intensity=30 rpm. The slow-mixing intensity was more sensitive than the rapid-mixing intensity to the P removal efficiency when [TiCl₄] was low (0.25≤[TiCl₄]≤0.27 mM).
