Wastewater treatment plants - Part 13: Chemical treatment - Treatment of wastewater by precipitation/flocculation
This document specifies the requirements for chemical treatment of wastewater by precipitation/flocculation for removal of phosphorus and suspended solids.
The application of polymers is not described in this document.
Differences in wastewater treatment throughout Europe have led to a variety of practices being developed. This document gives fundamental information about the practices; this standard has not attempted to specify all available practices.
NOTE Chemical treatment can be performed in combination with primary and more commonly with secondary treatment, but it can also be performed as separate tertiary treatment, usually in combination with filtration (see EN 12255-16). Chemical treatment can provide a potential contribution to the circular economy through the recovery of materials, such as phosphorus, from wastewater or sludge.
Kläranlagen - Teil 13: Chemische Behandlung - Abwasserbehandlung durch Fällung/Flockung
Dieses Dokument legt Anforderungen an die chemische Abwasserbehandlung durch Fällung/Flockung zur Phosphorelimination und zur Abscheidung abfiltrierbarer Stoffe fest.
Die Anwendung von Polyelektrolyten wird in diesem Dokument nicht beschrieben.
Die Unterschiede bei der Abwasserbehandlung in Europa haben zu einer Vielzahl von Verfahrensweisen geführt. Dieses Dokument enthält grundsätzliche Angaben zu den Verfahrensweisen; es legt jedoch nicht alle Einzelheiten jeder Verfahrensweise.
ANMERKUNG Die chemische Behandlung kann in der Vorklärung oder üblicher im zweiten Reinigungsteil erfolgen. Sie kann aber auch als getrennter dritter Reinigungsteil gemeinsam mit der Filtration durchgeführt werden (siehe EN 12255-16). Durch die Rückgewinnung von Stoffen, wie z. B. Phosphor, aus dem Abwasser oder dem Schlamm, kann die chemische Behandlung entscheidend zur Kreislaufwirtschaft beitragen.
Stations d'épuration - Partie 13: Traitement chimique - Traitement des eaux usées par précipitation/floculation
Le présent document 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 le présent document.
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. Le présent document donne des informations de base sur ces pratiques ; il n’est pas destiné à spécifier toutes les pratiques disponibles.
NOTE Un traitement chimique peut être effectué en association avec le traitement primaire et plus généralement avec le traitement secondaire, mais il peut également être réalisé en tant que traitement tertiaire séparé, généralement en association avec la filtration (voir EN 12255-16). Le traitement chimique peut contribuer à l’économie circulaire grâce à la récupération de matériaux, comme le phosphore, des eaux usées ou des boues.
Čistilne naprave za odpadno vodo - 13. del: Kemijsko čiščenje odpadnih vod z obarjanjem/kosmičenjem
Ta dokument določa zahteve za kemijsko čiščenje odpadnih voda z obarjanjem/kosmičenjem, ki je namenjeno odstranjevanju trdnega fosforja ali neraztopljenih trdnih snovi.
Uporaba polimerov v tem dokumentu ni opisana.
Zaradi različnih postopkov čiščenja odpadnih voda v Evropi so se razvile različne prakse. Ta standard podaja osnovne informacije o teh praksah; namen standarda ni, da se določijo vse razpoložljive prakse.
OPOMBA: Kemijsko čiščenje je mogoče izvesti v kombinaciji s primarnim ali sekundarnim čiščenjem, kar je pogostejša praksa, pa tudi kot ločeno terciarno čiščenje, običajno skupaj s filtracijo (glej standard EN 12255-16). S kemičnim čiščenjem je mogoče prispevati h krožnemu gospodarstvu, in sicer s predelavo materialov, kot je fosfor, pridobljen iz odpadne vode ali blata.
