Abstract

Oil contained in domestic and industrial wastewater or marine spilled oil gives rise to severe environmental pollution issues such as water pollution and ecosystem destruction. The membrane filtration method as one of representative oil/water separation strategies has technological challenges such as membrane fouling and low separation rate. In this work, we devise a 3D-printed microhydrocyclone for oil/water separation by utilizing a digital lighting processing-based 3D printer. We demonstrate that the 3D-printed microhydrocyclone can effectively separate oil and water phases from oil-in-water emulsion.

생활 폐수나 산업 폐수에 포함된 오일이나 해양 유출유 등은 수질오염 및 생태계 파괴 등의 심각한 환경오염 문제를 야기하고 있다. 대표적인 유수분리기술인 필터(또는 멤브레인)를 사용하는 경우에 분리막의 파울링, 낮은 처리용량 등의 기술적 제약이 있다. 본 연구에서는 원심력을 이용하여 유체내의 입자상 물질이나 밀도가 다른 액체-액체 혼합물을 분리하는 장치인 하이드로사이클론의 장점을 활용하며, 동시에 분리 효율을 증대시키 위하여 고해상도의 3D 프린팅 기술을 도입하여 스케일 다운된 마이크로하이드로사이클론을 제작하였다. 본 연구에서 개발한 마이크로하이드로사이클론을 통해 탈이온수와 올리브유로 이루어져 있는 수중유상 에멀젼을 효과적으로 분리할 수 있음을 증명하였다.
