Characterization of sludges - Filtration properties - Part 4: Determination of the drainability of flocculated sludges
This European Standard specifies a method for the determination of drainability of flocculated sludges. It is applicable to sludge and sludge suspensions from:
a) storm water handling;
b) urban wastewater collecting systems;
c) urban wastewater treatment plants;
d) treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271/EEC);
e) water supply treatment plants.
This method is also applicable to sludge suspensions from other origin.
Charakterisierung von Schlämmen — Filtrationseigenschaften — Teil 4: Bestimmung der Entwässerbarkeit geflockter Schlämme
Dieses Dokument legt ein Verfahren zur Bestimmung der Entwässerbarkeit geflockter Schlämme fest. Das
Dokument gilt für Schlämme und Schlammsuspensionen aus folgenden Bereichen:
a) Behandlung von Regenwasser;
b) Kanalisationssysteme für kommunales Abwasser;
c) Anlagen für die Behandlung von kommunalem Abwasser;
d) Behandlung von industriellem Abwasser, die auf ähnliche Weise erfolgt wie die von kommunalem
Abwasser (wie in der Richtlinie 91/271/EWG festgelegt);
e) Wasseraufbereitungsanlagen.
Dieses Verfahren ist auch auf Schlammsuspensionen anderer Herkunft anwendbar.
Caractérisation des boues - Propriétés de filtration - Partie 4: Détermination de l'aptitude à l'égouttage des boues floculées
La présente Norme européenne spécifie une méthode de détermination de l'aptitude à l'égouttage des boues
floculées. Elle s'applique aux boues et aux suspensions concentrées issues :
a) de la collecte des eaux pluviales ;
b) de systèmes de collecte des eaux usées urbaines ;
c) de stations d'épuration des eaux usées urbaines ;
d) de l'épuration des eaux usées industrielles semblables aux eaux usées urbaines (définie dans la
Directive 91/271/CEE) ;
e) d'usines de production d'eau potable.
Cette méthode s'applique aussi aux suspensions concentrées d’origines différentes.
Karakterizacija blata - Lastnosti filtriranja - 4. del: Določevanje prepustnosti kosmičenega blata
Ta evropski standard opredeljuje metodo za določevanje prepustnosti kosmičnega blata. Velja za blato in suspenzije blata iz: a) ravnanja z vodo ob neurjih; b) urbanih sistemov zbiranja odpadne vode; c) čistilnih naprav za odpadno vodo; d) obravnavanja industrijske odpadne vode na podoben način kot urbane odpadne vode (kot je opredeljeno v Direktivi 91/271/EGS); čistilnih naprav za sistem oskrbe z vodo. Ta metoda se uporablja tudi za suspenzije blata drugih izvorov.
