Title
(EN) FLUID TREATMENT REACTOR
(FR) RÉACTEUR DE TRAITEMENT DE FLUIDE
Abstract
(EN)
A fluid treatment reactor is provided. Separate input ports for influent and recycled effluent serve to eliminate the need for pH adjustment or carbonate stripping of the influent and recycled effluent flows.
(FR)
L'invention porte sur un réacteur de traitement de fluide. Des orifices d'entrée séparés pour un influent et un effluent recyclé servent à éliminer le besoin d'un ajustement du pH ou un stripage de carbonate des écoulements d'influent et d'effluent recyclé.
