DIN EN 14742
Characterization of sludges - Laboratory chemical conditioning procedure; German version EN 14742:2015

Title (German)

Charakterisierung von Schlämmen - Laborverfahren zur chemischen Konditionierung; Deutsche Fassung EN 14742:2015

Overview

This method gives a standardized procedure for the conditioning operation when selecting a conditioning product at laboratory scale and also for the production of flocculated thickened sludge for subsequent dewatering tests. These tests may also provide details regarding energy requirements, provided information on stirring power is available. The laboratory 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 this European Standard applies 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.
