Title (EN) WASTEWATER TREATMENT WITH CUSTOMIZED PHOSPHATE CONTROL
(FR) TRAITEMENT DES EAUX USÉES AVEC RÉGULATION DE PHOSPHATE PERSONNALISÉE
Abstract:
(EN) Systems and methods for the treatment of wastewater are provided. By incorporating one or more intermediate phosphate recovery reactors and manipulating the effluent and/or solid streams from those reactors, the systems and methods provide effluent and solid streams having customized phosphate content throughout the wastewater treatment process.
(FR) L’invention concerne des systèmes et des procédés pour le traitement des eaux usées. Par incorporation d'un ou de plusieurs réacteurs de récupération de phosphate intermédiaire et manipulation des flux d'effluents et/ou de solides provenant de ces réacteurs, les systèmes et les procédés fournissent des flux d'effluents et de solides ayant une teneur en phosphate personnalisée tout au long du processus de traitement des eaux usées.
