Abstract

Confectionary effluents are typical examples of strong wastes of biodegradable nature, quite suitable for respirometric analysis. Three different confectionary effluents have been subjected to a treatablity-oriented characterization, mainly by means of respirometric methods, yielding meaningful results on COD fractionation and significant kinetic coefficients. Experimental values have been tested by a multi-component mathematical model using the endogenous decay approach and hydrolysis rate constants corresponding to the slowly biodegradable COD fractions have been evaluated using curve fitting.
