WebThis process principle comes from the Chudoba works (1973) aimed at controlling filament bulking and at enhancing the sludge’s sedimentation capacity. The principle consists in creating an area with a high concentration of soluble assimilable substrate that stimulates the substrate’s uptake rates and storage capacity for non-filament type germs. WebThe results of this work demonstrated that the proposed models developed as an update of existing models based on conventional activated sludges, can be explicitly used in activated sludge plants to predict the impact of Al 3+ dosing concentrations on the settleability of activated sludge.

As ... WebThe content and volume of sludge recycled directly impacts the system’s performance. Thus, sludge handling processes may have to be modified to achieve optimal TN and TP removal efficiencies. For example, some polymers in sludge dewatering could inhibit nitrification when recycled.
