Characterisation of sludges - Filtration properties - Part 2: Determination of the specific resistance to filtration
|Publication Date:||1 June 2013|
|ICS Code (Liquid wastes. Sludge):||13.030.20|
This European Standard specifies a method for determining the specific resistance to filtration of conditioned and non-conditioned sludges, provided that no sedimentation occurs during filtration (i.e. single phase suspension with particles in suspension).
This European Standard is applicable to sludges and sludge suspensions from:
- storm water handling;
- urban wastewater collecting systems;
- urban wastewater treatment plants;
- industrial wastewater that has been treated similarly 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.
