Modelling of activated sludge for textile wastewaters

A comprehensive evaluation of four different textile wastewaters was carrie d out to set the experimental basis for the modelling of activated sludge p rocess. Experiments involved beside conventional characterization, detailed COD fractionation and assessment of major kinetic and stoichiometric coeff icients by means of respirometric measurements. A multi-component model bas ed on the endogenous decay concept was used for the kinetic interpretation and design of activated sludge. The fate and variation of major process com ponents affecting effluent quality with the sludge age were evaluated by me ans of model simulations. (C) 1998 Published by Elsevier Science Ltd.
