Abstract
Sludge produced from water treatment plants contains plenty of aluminum due to addition of coagulants, polyaluminum chloride(PACI) which has been widely used in most of water treatment plants. however. the whole of PACI is imported from other countries. In this research. the effective methods for recycling PACI from sludge of water treatment plants were developed and evaluated. Aluminum chloride hexahydrate(
정수장에서 발생하는 슬러지에는 처리과정에서 주입되는 응집제로 인하여 다량의 알루미늄 성분이 함유되어 있으며, 정수장에서 널리 사용되고 있는 폴리염화알루미늄(PACI) 응집제의 원료는 전량 수입되고 있는 실정이다. 본 연구는 정수 슬러지의 효과적인 재활용을 목적으로 수행되었다. 슬러지내의 알루미늄 성분을 염산(HCI)으로 용출하고 HCI 가스를 주입하여 염화알루미늄수화물(
