초록

본 연구에서는 초순수 생산을 위한 개별공정들의 특성을 고려하여 공정조합 최적화 방안을 결정하는 기법을 연구하였다. 산업 활동에 사용하는 공업용수 중 고도의 기술집합 산업에서 요구되는 고순도 용수인 초순수를 생산하는 공정은 여과, 이온교환, 역삼투, 탈기, 자외선 산화 등 이 있다. 초순수 공정은 다양한 15~20개 정도의 수처리 단위 공정이 조합을 이루고 있다. 본 연구에서는 초순수 생산 모형플랜트를 운영하여 다양한 처리 공정의 조합을 통해 수질 및 경제성을 고려하여 평가하였다. 평가된 19종류의 공정조합 중 11개 공정조합이 목표로 하는 최종 수질을 만족했다. 이러한 11종의 공정조합에 대해 안정성과 경제성을 평가하였다.

In this paper, the technique that determines efficient process combinations for the ultrapure water production was studied. The ultrapure water is one of the industrial water used in industrial activity and required in the advanced technology integrated industry. It is produced by combined process including filtration, ion exchange processes, the reverse osmosis (RO) process, degassing (DG) process and UV-oxidation (UVox) process. An ultrapure water production process consists of 15-20 different water treatment unit process. In this study, a pilot plant was built and operated to research the design parameters for the individual process. Through the pilot plant operation, 19 effective combinations were optimized among various processes. And then, 11 of them satisfied the final quality of the ultrapure water. The stability and economic feasibility were evaluated about the final 11 process combinations.
