Abstract
The present invention is an aquifer storage and recovery system using a natural coagulant, in which in purifying raw water through aquifer storage and recovery, assimilable organic carbon (AOC) included in the raw water is effectively removed using a natural coagulant produced in the aquifer storage and recovery process, thereby reducing the time required to purify raw water by aquifer storage and recovery.
