Bibliography
This European Standard specifies a method for the determination of drainability of flocculated sludges. It is applicable to sludge and sludge suspensions from: a)storm water handling;b)urban wastewater collecting systems;c)urban wastewater treatment plants;d)treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271/EEC);e)water supply treatment plants.This method is also applicable to sludge suspensions from other origin.
