Characterisation of sludges - Settling properties - Part 2: Determination of thickenability

This document specifies a method for the determination of the thickenability of sludge suspensions. This document is applicable to sludge suspensions from:
¾   storm water handling;
¾   urban wastewater collecting systems;
¾   urban wastewater treatment plants;
¾   treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271 EEC);
¾   water supply treatment plants.
This method is also applicable to sludge suspensions from other origin.

Charakterisierung von Schlämmen - Absetzeigenschaften - Teil 2: Bestimmung der Eindickbarkeit

Dieses Dokument legt ein Verfahren zur Bestimmung der Eindickbarkeit von Schlammsuspensionen fest. Diese Dokument gilt für Schlammsuspensionen aus folgenden Bereichen:
-   Behandlung von Regenwasser;
-   Kanalisationssysteme für kommunales Abwasser;
-   Anlagen für die Behandlung von kommunalem Abwasser;
-   Behandlung von industriellem Abwasser, die auf ähnliche Weise erfolgt wie die von kommunalem Abwasser (wie in der Richtlinie 91/271/EWG festgelegt);
-   Aufbereitungsanlagen für die Wasserversorgung.
Dieses Verfahren ist auch auf Schlammsuspensionen von anderer Herkunft anwendbar.

Caractérisation des boues - Propriétés de sédimentation - Partie 2: Détermination de l'aptitude à l'épaississement

Le présent document spécifie une méthode de détermination de l’aptitude à l’épaississement de suspensions de boues. Il s’applique aux 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 ;
-   de l’épuration des eaux industrielles semblables aux eaux usées urbaines (comme défini dans la Directive 91/271/CEE) ;
-   des usines de production d’eau potable.
Cette méthode s’applique également aux suspensions de boues ayant une autre origine.
