Abstract
기포포말에 의한 미립자 분리시 입자의 분리기구를 충돌영역과 확산영역으로 나누어 각 영역에서의 모델식을 제시하고, 이들을 실험치와 비교하였으며, 두 영역에 함께 속하는 입자들의 혼합 영역에 대하여서도 각 모델식을 동시에 적용하여 모델식의 적응성을 검토하였다.
본 연구에서의 입자는 평균입도가 5.0μm, 0.9μm, 0.3μm의 α-Al2O3를, 계면활성제는 Cetylethyldimethyl Ammonium Bromide를 각각 사용하였고, 이들에 적용할 수 있는 실험식을 각각 구하였다.

A theoretical model was proposed for the removal of fine particles by dispersed air flotation.
This model was divided into collision and diffusion region.
The results from the model were compared with those from experiments. Experiments were carried out using Cetylethyldemethyl Ammonium Bromide and suspension of α-Al2O3 in the batch system.
A mixed system composed of both region particles was well expressed by the model combining the collision and diffusion model.
