Abstract

A phosphorus removal system is operable to remove phosphorus from an influent. The system includes a first section receiving the influent and discharging a first flow. A first coagulant inlet is positioned upstream of the first section and is in fluid communication with the influent to introduce a first coagulant selected to precipitate phosphorus. A second section receives the first flow and discharges a second flow, and a third section receives the second flow and discharges an effluent. A second coagulant inlet is positioned downstream of the first section and upstream of the third section to introduce a second coagulant selected to precipitate phosphorus.
