The Characteristics of Municipal wastewater Sludge Dewatering Using Oyster Shell Powder
굴껍질을 이용한 하수슬러지의 탈수특성에 관한 기초연구
Abstract
The objective of this study is to examine the subsitiution effect of the waste oyster shell powder as the conditioning agent in municipal wasterwater sludge dewatering process. Beacuse the oyster shells have a large amount(about 38% by weight) of alkaline minerals, such as calcium and magnesium, they are thought to have the potential as a good conditioning agent. In this study, the physico-chemical properties of powdered oyster shells (75
