Bibliography

This part of the European Standard specifies a method for determining the flowability, as defined in CEN/TR 15463, of sludge by means of the extrusion tube apparatus.This part of this European Standard is applicable to sludge and sludge suspensions from:—storm water handling;—urban wastewater collecting systems;—urban wastewater treatment plants;—plants treating industrial wastewater similar 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.
