응집·침전 공정에서 PAC를 이용한 낙동강 원수의 DOC 제거 및 분자량 분포 특성
Characteristics of Apparent Molecular Weight Distribution and Removal of DOC by Coagulation and Sedimentation Process with Polyaluminum Chloride in Nakdong River Water
초록
The objective of present work is to evaluate the optimum coagulation conditions in order to decrease dissolved organic carbon(DOC) and turbidity at different polyaluminum chloride dosage and pH from Nakdong River water. This studies were carried out to examine distribution on apparent molecular weight(AMW) of DOC in the Nakdong River water and its coagulation-sedimentation water. On the basis of jar tests, at the optimum coagulation pH in order to decrease DOC and turbidity were pH 5.0~6.0 and optimum dosage of polyaluminum chloride were 10~15mg
