포말부상법을 이용한 카오린 현탁액의 제거 = Removal of Kaolin Suspension by Form Flotation

다국어 초록 (Multilingual Abstract)

In order to remove the turbidity of kaolin suspension, foam separation method was carried out by using casein and gelatin for surface active materials, and alum and FeCl₃ for coagulants.
The optimum condition of retention time, pH, surface active material, and air flow rate were showed as 1.0min, pH 4, 40mg/L, 1.0L/min on case of casein dosing, 3.0min, pH 5, 40mg/L, 1.0L/min on case of gelatin dosing, 2.0min, pH 9, 40mg/L, 0.5L/min on case of alum-casein dosing, 2.5min, pH 6, 60mg/L, 2.0L/min on case of alum-gelatin dosing, 2.0min, pH 9, 40mg/L, 0.5L/min on case of FeCl₃-casein dosing, and 2.5min, pH 7, 50mg/L, 0.4L/min on case of FeCl₃-gelatin dosing.
The turbidity removal efficiency for optimal pH were recorded 60.5% for casein, 37.4% for gelatin, 90.0% for alum-casein, 67.2% for alum-gelatin, 98.5% for FeCl₃-casein and 95.9% for FeCl₃-gelatin.
