This standard BS EN 14701-2:2013 Characterisation of sludges. Filtration properties is classified in these ICS categories:
13.030.20 Liquid wastes. Sludge
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.
