摘要
In this study, the phosphorous removal efficiency of partitionable-space enhanced coagulation (PEC) technology has been investigated. A series of continuous experiments was conducted to find out the influence of operating parameters. With increase in the elapsed treatment time, the phosphorus removal rates improved progressively during 1.5-3 h and the reactor reached a steady state after 4 h. This improved performance is mainly attributed to the partitionable-space and flocculation filter in the PEC reactor which enhanced the coagulation process. The flocs formed exhibited excellent settling characteristics by quickly settling out within the first 15 min.
