Characterisation of sludges - Settling properties - Part 3: Determination of zone settling velocity (ZSV)

This document specifies a method for determining the zone settling velocity (ZSV) and the Compression point.
This document is applicable to sludge and sludge suspensions from:
-   storm water handling;
-   urban wastewater collecting systems;
-   urban wastewater treatment plants;
-   plants treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271/EEC);
-   water supply treatment plants.
This method is also applicable to sludge and sludge suspensions of other origins.

Charakterisierung von Schlämmen - Absetzeigenschaften - Teil 3: Bestimmung der Zonen-Absetzgeschwindigkeit (ZSV)

Dieses Dokument legt ein Verfahren zur Bestimmung der Zonen Absetzgeschwindigkeit (en: zone settling velocity, ZSV) und des Kompressionspunktes fest.
Dieses Dokument gilt für Schlamm und Schlammsuspensionen aus den folgenden Bereichen:
- Behandlung von Regenwasser;
- Kanalisationssysteme für kommunales Abwasser;
- Anlagen für die Behandlung von kommunalem Abwasser;
- Anlagen für die Behandlung von industriellem Abwasser, die auf ähnliche Weise erfolgt wie die von kommunalem Abwasser (wie in Richtlinie 91/271/EWG festgelegt);
- Aufbereitungsanlagen für die Wasserversorgung.
Dieses Verfahren ist auch auf Schlamm und Schlammsuspensionen anderer Herkunft anwendbar.

Caractérisation des boues - Propriétés de sédimentation - Partie 3 : Détermination de la vitesse du front de sédimentation (ZSV)

Le présent document spécifie une méthode de détermination de la vitesse du front de sédimentation (ZSV) et du point de compression.
Le présent document est applicable aux boues et suspensions de boues provenant :
-   de la collecte des eaux pluviales ;
-   des systèmes de collecte des eaux usées urbaines ;
-   des stations d’épuration des eaux usées urbaines ;
-   des stations d’épuration des eaux industrielles assimilées (telles que définies par la Directive 91/271/CEE) ;
-   des stations de traitement des eaux de distribution.
Cette méthode s’applique également aux boues et aux suspensions de boues d’autres origines.

Karakterizacija blata - Lastnosti usedanja - 3. del: Določevanje hitrosti usedanja po območjih

Ta osnutek evropskega standarda določa metodo za določanje hitrosti namestitve območja (ZSV) in točke kompresije.
Ta osnutek evropskega standarda se uporablja za blato in suspenzije blata iz:
– sistemov za zbiranje deževnice;
– zbiralnih sistemov za mestno odpadno vodo;
– čistilnih naprav za mestno odpadno vodo;
– naprav za čiščenje industrijske odpadne vode na podoben način kot komunalne odpadne vode (kot je opredeljeno v Direktivi 91/271/EGS);
– čistilnih naprav v sistemih oskrbe z vodo.
Ta metoda se uporablja tudi za blato in suspenzije blata drugega izvora.
