NEN-EN 14742 assessment of sludge dewaterability is sensitive to the operating procedure adopted for the conditioning step. No generalized ranking of products in order of effectiveness can be given since the ranking changes with the sludge type, dosage of conditioning agent, degree of shearing and dewatering device. The scope of NEN-EN 14742 for sludges and 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 plants. This method is applicable to sludge and suspensions of other origin.
