Abstract
- This study evaluates the efficacy of titanium tetrachloride (TiCl 4 ) on phosphorus (P) removal in synthetic wastewater. Jar test experiments were performed at various TiCl 4 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 TiCl 4 concentration ([TiCl 4 ])=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 [TiCl 4 ] was low (0.25≤[TiCl 4 ]≤0.27 mM). Key Words : Coagulation, Mixing Intensity, pH, Phosphorus, Titanium Tetrachloride 요약: 본 연구는 TiCl 4 의 농도(0.25-0.59 mM)와 급속교반속도(100-250 rpm), 완속교반속도(30-60 rpm)의 변화가 인 제거효율에 미치는 영향을 알아보고자 하였다. 응집제 농도가 0.25≤[TiCl 4 ]≤0.39 mM 범위에서 인 제거 효율은 TiCl 4 의 농도가 증가할수록 증가하였으며 처리후 인의 농도는 0.2 mg/L 이하였다. 응집제 농도 0.39 mM, 급속교반속도 100 rpm, 완속교반속도 30 rpm에서 인 제거효율이 약 99%로 가장 높았다.
