Wastewater treatment plants - Part 13: Chemical treatment - Treatment of wastewater by precipitation/flocculation

This European Standard gives the application, procedure and specifies the requirements for chemical treatment of wastewater for removal of phosphorous and suspended solids. Differences in wastewaste treatment throughout Europe have led to a variety of practices being developed. This Standard gives fundamental informations about the practices; this Standard has not attempted to specify all available practices.

Kläranlagen - Teil 13: Chemische Behandlung - Abwasserbehandlung durch Fällung/Flockung

Diese Europäische Norm zeigt das Einsatzgebiet und das Verfahren der chemischen Behandlung von Abwasser zur Phosphatelimination und zur Abscheidung suspendierter Stoffe auf und legt die Anforderungen an dieses Verfahren fest. Die Unterschiede in Planung und Bau von Kläranlagen in Europa haben zu einer Vielzahl von Verfahrensweisen geführt. Diese Norm enthält grundsätzliche Angaben zu den Verfahrensweisen; sie beschreibt jedoch nicht alle Einzelheiten jeder Verfahrensweise.

Stations d'épuration - Partie 13: Traitement chimique - Traitement des eaux usées par précipitation/floculation

La présente Norme européenne définit les exigences relatives au traitement chimique des eaux usées par précipitation/floculation dans le but d'en éliminer le phosphore et les matières solides en suspension.
L'application des polymères n'est pas décrite dans la présente Norme européenne.
Les différences qui existent dans le traitement des eaux usées d'un pays européen à l'autre ont conduit à la mise au point de pratiques variées. La présente norme donne des informations de base sur ces pratiques ; elle n'est pas destinée à spécifier toutes les pratiques disponibles.
Des informations détaillées complémentaires de la présente norme sont disponibles dans la bibliographie.
