회분식과 연속식의 액막법에 의해 폐수중의 페놀제거에 관하여 실험 조사하였다. 실험 변수로서 교반 속도, 폐수중의 페놀 농도, 수산화나트륨 농도, 계면활성제의 농도, 계면활성제 용액과 수산화나트륨 용액의 용적비, 페놀 폐수와 w/o 에멀젼의 용적비 등의 영향을 회분식 실험에 의해 관찰하였다.
2-단의 교반조와 분리조를 이용한 연속 실험에서 1 wt%와 0.5 wt%의 수산화 나트륨 용액을 이용하여 1,000 ppm의 페놀 폐수를 환경 허용 기준치인 5 ppm 이하로 제거할 수 있었다. 용매 추출법이나 미생물에 의한 처리와 같은 종래의 페놀 제거 방법에 대한 액막법의 장점에 관하여 조사하였다.

Experimental investigation has been made on the removal of phenol from waste water by liquid membrane technique employing both batch and continuous operations. The effects of system variables, such as mixing intensity, phenol concenuration in the feed, concentration in the feed, concentration of sodium hydroxide, surfactant concentration, volume ration of surfactant solution to sodium hydroxide solution and volume ratio of feed to w/o emlsion, were analyzed systematically with batch opdration. For the continuous operation with a two-stage mixer-and-settler, the level of phenol concentration can be lowered by using 1 wt. percent and 0.5 wt. percent sodium hydroxide solution from 1,000 ppm. to below 5 ppm. which is the upper limit in the environmental protection act. Some advantages of liquid membrane technique over conventional removal methods such as solvent extraction and bioligical treatment were observed in the experiment.
