DIN EN 14701-2:2013-07

This document 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 document 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.
