Title (EN) TREATMENT OF SEA DISCHARGED SEWAGE
(FR) TRAITEMENT D"EAUX D"EGOUTS POUR LEUR DECHARGE EN MER
Abstract: front page image
(EN)Method and apparatus for treating sewage destined for discharge into the sea. The fluid treatment process comprises conducting the sewage through bar racks, and degritters (3) to remove large scale particles, extracting intermediate size particulate material in a rotary drum screen (5), introducing a chemical composition into the fluid to promote coagulation of particles having an average particle size of less than about 1 micron, filtering the fluid containing said coagulated particles through a deep bed multimedia filter (9), adjusting the quantity of dissolved oxygen in the filtrate to a predetermined level and discharging the oxygenated fluid to the sea some distance offshore to permit dispersal of any remaining contaminants by action of wind and currents.
(FR)Procede et appareillage pour le traitement d"eaux d"egouts pour leur decharge en mer. Le procede de traitement fluide comprend la conduite des eaux a travers des grilles a barreaux et des epierreurs (3) pour enlever les particules de grandes tailles, l"extraction du materiel particulaire de taille intermediaire dans un tamis a tambour rotatif (5), l"introduction d"une composition chimique dans le fluide pour promouvoir la coagulation des particules ayant une taille moyenne inferieure a environ 1 micron, la filtration du fluide contenant ces particules coagulees a travers une filtre profond a elements multiples (9), l"ajustement de la quantite d"oxygene dissoute a un niveau predetermine et la decharge du liquide oxygene en mer a quelque distance au large afin de permettre la dispersion des contaminants residuels par le vent et les courants.
