Characterisation of sludges - Filtration properties - Part 2: Determination of the specific resistance to filtration; German version :2013
N EN 14701-2
Annotation
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.

Характеристика грязей - качества фильтрации - часть 2: Определение специфического сопротивления фильтрации
Этот европейский стандарт указывает метод для определения удельного сопротивления фильтрации обусловленных и необусловленных отстоев, при условии, что никакое осаждение не происходит во время фильтрации (т.е. единственная приостановка фазы с частицами во взвешенном состоянии).
