Abstract
Description
Claims (2)
- 역삼투막, 나노막, 한외여과막, 정밀여과막 등으로 막 분리하여 산업용수 및 폐수를 처리함에 있어 분리막과 분리막 사이의 투과수 통로에 전도성의 플라스틱 망 또는 금속망을 삽입한 분리막셀을 대치 또는 적층하고 직류방식으로 전류밀도 0.1~80A/d㎡의 범위내에서 양전기(+)와 음전기(-)가 상호작용 하도록 극변환 방식으로 전기를 통하게 하는 막분리 방법.
- 청구 1항 중 분리막과 처리수에 초음파 진동을 주어 처리수의 물질을 균질화하여 농도분극 현상을 막고 분리막의 오염을 방지하는 막 분리 처리 방법.
