Abstract

A magnetic fluid separation technology was confirmed to be very effective to remove the suspended solids from contaminated water. We have surveyed on the effects of operating variables on the characteristics of suspended solids(SS) removal investigated through the test runs using magnetic powder. Magnetic flocculation here formed by adsorbing fine magnetites on the surface of suspended solid was observed. The strength of magnet was of significance in determining the SS removal efficiency.

수중에서 인, 질소의 함유농도는 부유고형물의 농도에 비례하여 증가하기 때문에 부유고형물의 제거는 유기물과 함께 질소, 인을 동시에 제거할 수 있다. 부유고형물은 수중에 미분체를 투입하면 투입된 미분체와 부유고형물 사이에는 반데르발스 힘과 같은 인력이 작용하여 응집이 형성되고 이 응집덩어리는 자성을 띠게 된다. 이와 같은 자성응집덩어리를 자력에 의해 형성된 자성 매트릭스에 직접 부착시켜 분리 제거함으로써 오수를 세정할 수 있다. 본 자료는 자성분리기술과 관련하여 오수 내의 부유고형물의 제거특성에 대한 것을 실험적으로 평가하고 부유물의 제거효율에 대하여 규명하고자 한다.
