(Main)Wastewater treatment plants - Part 3: Preliminary treatment
Wastewater treatment plants - Part 3: Preliminary treatment
This document specifies design principles and performance requirements for preliminary wastewater treatment using screens with a mesh size above 50 microns, at plants serving more than 50 PT.
NOTE 1 For micro-screens with a mesh size below 50 microns see EN 12255-16.
NOTE 2 The primary application of this document is for wastewater treatment plants designed for the treatment of domestic and municipal wastewater. However, it contains information that may also be useful for commercial and industrial wastewater pretreatment and for combined sewer overflows (CSO).
This document applies in combination with EN 12255-1 and EN 12255-10.
Kläranlagen - Teil 3: Abwasservorreinigung
Dieses Dokument legt Planungsgrundsätze und Leistungsanforderungen für die Vorreinigung von Abwasser mithilfe von Feinrechen oder sieben mit einer Maschenweite über 50 Mikrometer in Kläranlagen mit einem EW über 50 fest.
ANMERKUNG 1 Für Mikrosiebe mit einer Maschenweite unter 50 Mikrometer siehe EN 12255-16.
ANMERKUNG 2 Vorrangig gilt dieses Dokument für Kläranlagen, die zur Behandlung von häuslichem und kommunalem Abwasser ausgelegt sind. Es enthält jedoch auch Informationen, die für die Vorreinigung von gewerblichem und industriellem Abwasser und für Mischwasserüberläufe (en: combined sewer overflows, CSO) von Nutzen sein können.
Dieses Dokument gilt gemeinsam mit EN 12255-1 und EN 12255-10.
Stations d’épuration - Partie 3 : Prétraitements
Le présent document spécifie les principes de conception et les prescriptions de performance pour le traitement préliminaire des eaux usées au moyen de dégrilleurs ayant une taille de dégrillage supérieure à 50 microns, au niveau de stations desservant plus de 50 EH.
NOTE 1 Pour les micro dégrilleurs de taille de dégrillage inférieure à 50 microns, voir EN 12255-16.
NOTE 2 Le présent document s’applique principalement aux stations d’épuration conçues pour le traitement des eaux usées domestiques et municipales. Toutefois, il contient des informations qui peuvent également être utiles pour le prétraitement des eaux résiduaires industrielles et commerciales et pour les déversoirs d’orage.
Le présent document s’applique conjointement à l’EN 12255-1 et à l’EN 12255-10.
Čistilne naprave za odpadno vodo - 3. del: Predhodna obdelava
Ta dokument določa načela načrtovanja in zahteve za predhodno obdelavo odpadne vode s siti z velikostjo mreže več kot 50 mikronov v čistilnih napravah za odpadno vodo za več kot 50 populacijskih ekvivalentov.
OPOMBA 1: Za mikro sita z velikostjo mreže, manjšo od 50 mikronov, glej standard EN 12255-16.
OPOMBA 2: Ta dokument se v prvi vrsti uporablja za čistilne naprave za odpadne vode, ki so zasnovane za čiščenje gospodinjske in komunalne odpadne vode. Vseeno pa vsebuje informacije, ki so lahko prav tako uporabne za predhodno obdelavo komercialne in industrijske odpadne vode in za zadrževalnike odpadne vode (CSO).
Ta dokument se uporablja v kombinaciji s standardom EN 12255-1 in standardom EN 12255-10.
