Abstract

The sludge in passive treatment systems must be dewatered for final disposal because it contains a high content of water. Ton bags have been used for dewatering sludge and have a drawback to require a long time of work. This study summarizes a geotextile tube technology that overcomes a shortcoming. Geotextile tubes are being used to dewater the sludge from water treatment as well as slurry from mineral process. The larger particles flocculated by addition of polymers to sludge are left in a geotextile tube and the water is rapidly filtered. This geotextile tube technology is determined to reduce the time needed to decrease duration time of the traditional ton bag method.

자연정화 처리장에서 발생하는 슬러지는 함수율이 높아서 최종 처분을 위해서는 탈수를 해야 한다. 기존의 탈수법인 톤 백을 이용하는 방식은 탈수가 오래 걸리는 단점이 있다. 이러한 단점을 극복하는 지오텍스타일 튜브 (geotextile tube) 탈수 기술을 요약하였다. 광산배수 처리 슬러지는 물론 광물처리 슬러리의 탈수를 위해서 지오텍스타일 튜브가 사용되고 있다. 폴리머를 사용해서 미세 입자를 크게 만들어 지오텍스타일 튜브내에 슬러지를 남게 하고 물은 신속히 탈수 시킨다. 본 기술이 종래 톤 백(ton bag) 방식보다 탈수 기간을 단축 하는 기술로 판단된다.
