Enhancement of Sludge Dewaterability using a Starfish and the Radiation Technology
전자선과 불가사리 분말을 이용한 하수슬러지 탈수능 향상
- Published : 2004.07.01
This study was focused on the manufacturing method of a dewatering aid, which would reduce the water content of the sludge cake by enhancing the dewaterability of sewage sludge. The pretreatment technology for sludge by using radiation and among diverse discarded resources were starfish selected as the material to manufacture the dewatering aid. Starfish went through the process of washing, drying, and pulverizing. The starfish powder made in this process was applied to the digested sludge generated at the sewage treatment plant of D City, and its effects were investigated. The starfish powder that was 300
