Title (EN) MEMBRANE WASTEWATER TREATMENT OF COMBINED SEWER OVERFLOWS AND SANITARY SEWER OVERFLOWS
(FR) TRAITEMENT PAR MEMBRANE DES EAUX USÉES DE TROP-PLEINS D'ÉGOUT SANITAIRE ET DE TROP-PLEINS D'ÉGOUT UNITAIRE
Abstract:
(EN) A wastewater treatment system includes a biological treatment plant and an auxiliary, non-biological treatment plant. The auxiliary plant receives overflow, which can be sanitary sewer overflow, combined sewer overflow or strictly storm overflow. Treatment is by coagulation and membrane separation, removing most bacteria. Following treatment the outflow can be discharged to streams.
(FR) L'invention concerne un système de traitement des eaux usées comprenant une installation de traitement biologique et une installation de traitement auxiliaire non biologique. L'installation auxiliaire reçoit un trop-plein, qui peut être un trop-plein d'égout sanitaire, un trop-plein d'égout unitaire ou un trop-plein d'orage strictement. Le traitement se fait par coagulation et séparation par membrane, ce qui permet d'éliminer la plupart des bactéries. Après le traitement, le débit sortant peut être évacué vers des cours d'eau.
