Title (EN) IMPROVED PHOSPHORUS REMOVAL SYSTEM AND PROCESS
(FR) SYSTEME ET PROCEDE AMELIORES D'ELIMINATION DU PHOSPHORE
Abstract:
(EN) 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.
(FR) L'invention concerne un système d'élimination du phosphore servant à éliminer le phosphore dans un influent. Ce système comprend une première section recevant l'influent et évacuant un premier flux. Une première entrée de coagulant est placée en amont de la première section et se trouve en communication fluidique avec l'influent pour introduire un premier coagulant choisi pour précipiter le phosphore. Une deuxième section reçoit le premier flux et évacue un deuxième flux et une troisième section reçoit ce deuxième flux et évacue un effluent. Une deuxième entrée de coagulant est placée en aval de la première section et en amont de la troisième section pour introduire un deuxième coagulant choisi pour précipiter le phosphore.
