Characterisation of sludges - Settling properties - Part 3 : determination of zone settling velocity (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 ; des stations de traitement des eaux de distribution. Cette méthode s'applique également aux boues et aux suspensions de boues d'autres origines.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
