BS EN 14701-2:2013

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.
