Characterization of sludges - Determination of sludge Particle and Floc size cen:proj:34491

Scope

The main problem of parameters and tests adopted for sludge characterisation is that they are generally specific to the method of treatment, but not able to give fundamental information on the sludge in question.
One of the most important parameters yielding basic information is the Particle and Floc size (this determination was also dealt with in the framework of European COST68 and 681). This parameter also strongly affects the performance of several sludge management operations.
Several procedures are available for evaluation of above parameter (e.g. direct examination, fractioning and counting), each showing some pros and cons.
This Technical Report will discuss applicability of all adopted measuring methods in order to propose a procedure to be possibly finalised in a standardised one.
