Title (EN) BIO-DAF SYSTEM FOR DOMESTIC AND INDUSTRIAL WASTEWATER TREATMENT
(FR) SYSTÈME BIO-FAD POUR LE TRAITEMENT D'EAUX USÉES DOMESTIQUES ET INDUSTRIELLES
Abstract:
(EN) A system for effectively removing biochemical oxygen demand (BOD), total suspended solids (TSS), ammonia, total nitrogen (TN), and total phosphorus (TP) from wastewater has integrated multiple physiochemical and biological treatment processes into one unit. This system includes a primary DAF unit, anoxic bio-media treatment zone, and a secondary DAF unit. The bio-media treatment zones may be used to remove BOD and TN and may be divided into a number of functional zones. Each functional zone can develop and accumulate optimized bacteria species and microorganisms based on incoming wastewater BOD and nutrient levels.
(FR) Un système permettant d'éliminer efficacement la demande biochimique en oxygène (DBO), le total des solides en suspension (TSS), l'ammoniac, l'azote total (AT) et le phosphore total (PT) des eaux usées présente de multiples processus de traitement physico-chimiques et biologiques intégrés en une seule unité. Ce système comprend une unité FAD primaire, une zone de traitement en milieu biologique anoxique et une unité FAD secondaire. Les zones de traitement en milieu biologique peuvent être utilisées pour éliminer la DBO et l'AT, et peuvent être divisées en un certain nombre de zones fonctionnelles. Chaque zone fonctionnelle peut développer et accumuler des espèces bactériennes optimisées et des micro-organismes à partir de la DBO des eaux usées entrantes et de la teneur en nutriments.
