포말분리 장치를 이용한 해수 중의 단백질 제거 특성을 조사한 결과, 단백질 농도가 높을 수록 또한 폭기량이 높을수록 단백질의 제거속도는 증가하는 것으로 나타났다. 이러한 각각의 제거특성을 통계학적으로 비선형 회귀분석하여 각각의 인자의 변화에 따른 단백질 농도의 변화를 다음의 식으로 나타낼 수 있었다. $$f;(Co,;u)=1.5712 imes10^{-7} imesCo^{3.061} imesu^{1.258}$$ 위 식을 이용하여 유한차분법으로 시뮬레이션을 수행한 결과 실제 포말분리 운전에서 나타난 결과와 상관성이 아주 높은 결과를 얻을 수 있었다.
Experiments were conducted to evaluate a experimental model developed for the protein removal by foam separation. The foam separator was operated in well-mixed tank which would be considered as a completely mixed condition. The feasibility of foam separation to remove protein from sea water was investigated. Protein removal characteristics of the foam separator were obtained by batch experiments. To find the effect of the operating parameter to protein removal rate, the foam separation was carried with variation of initial protein concentration and superficial air velocity. The result indicated that the protein removal efficiency was increased with increasing protein concentration and superficial air velocity. The relationship between operation parameters and protein removal rate were evaluated by non-linear regression as the form of exponential function, Using both relationships, the simplified model was determined. The simplified foam separator operation model was verified by the batch operation. The simulation results showed a good relationship with the experimental data.
