Title
Effect of H2O2 Addition on Ferric Coagulation for Phosphorus Removal
박성환 Sung Hwan Park , 문병현 Byung Hyun Moon
Abstract
In this study, the effect of H2O2 addition on ferric coagulation for phosphorus removal. The experiments were conducted under H2O2/Fe molar ratio of 0.4∼6.0; rapid mixing intensity with G value of 500 s-1. The effect of H2O2 injection sequence was investigated also. The characteristics of floc growth were measured by flocculation index (FSI) using the PDA. The removal efficiencies of phosphorus were increased as H2O2/Fe molar ratio increased. However, The removal efficiencies of phosphorus were decreased over the H2O2/Fe ratio 4. Higher removal efficiencies of phosphorus and floc size were observed with sequence dose of ferric coagulant and hydrogen peroxide.
