축전식 탈염기술은 에너지 절감형 탈염기술로 최근 연구결과물이 급증하는 추세에 있다. 초기에는 전극 소재개발이 주관심 분야였으나 소규모 제품화 단계에서 적층기술, 이온교환막 응용기술, 스택화 기술을 주로 개발해 왔다. 현재는 소규모 연수기나 정수기 규모로 개발하고 있으나 10,000 ㎥/일 규모의 공정수나 50,000 ㎥/일 규모 이상의 기수 담수화 적용을 위해서는 모듈의 대용량화, 대용량 전력 공급장치개발, 운전 기술 및 제어기술의 확보가 필요한 실정이다. 발전용수 등에서 요구되는 초순수 수질은 전기전도도로써 0.1~0.2 μS/cm 수준이다.

The dyeing wastewater contains considerable amounts of hardly biodegradable substances such as volatile organic compounds, surfactants, dyes, sizing agents. This work was carried out to investigate the feasibility and effectiveness of the MBR(Membrane Bio Reactor) process for treatment of dyeing wastewater. Ceramic membrane with pore size of 0.l ㎛ was selected due to the convenience of backwashing and higher flux. For 90 days operation of MBR, MLSS concentration in the bioreactor was increased from 4000㎎/L to 19,500㎎/L. At the beginning the permeation flux was about 45L/㎡-hr and reduced to 5.7L/㎡-hr after 90 days of operation. The permeation flux was recovered by backwashing at the beginning of operation, but, after long-term operation, permeate flux was not favorably recovered by backwashing only. Some elements such as Al, Si, Na, Cl, Fe, Sn and Cr which were mostly originated from influent might contribute membrane fouling. The removal efficiencies of SCOD_(cr) and color of MBR were 78.6% and 34.4% respectively. Despite of the increased MLSS concentration, removal efficiency of organic matters and color density was not significantly improved because microorganism which could utilize the organic matters did not fully developed. Thus in order to enhance the removal efficiency of MBR process, MLSS concentration in bioreactor is to be maintained in the range of 4000∼6000㎎/L and PACAS(Powdered Activated Carbon Activated Sludge) process is recommended.
