Activated sludge reactor model

This model considers the biological step only, i.e. the activated sludge reactor and the secondary settling. The model allows calculation of the concentration of LAS in the treated effluent, as a function of key plant operating parameters, Henry s Law constant, the partitioning coefficient solids/MLSS and kinetics of biodegradation of LAS. 

The activated sludge process for meat processing wastewater treatment was reported by Annachhatre and Bhamidimarri.37 When a model reactor was operated at an HRT of 5-15 h, a COD removal of more than 85% was achieved. The COD loading for the above performance was 3.2kg COD/(m3d). An SRT of 13 d resulted in almost complete nitrification. El-Gohary et al.30 reported that the activated sludge process reduced the BOD and COD of a potato-chips factory wastewater by 86% and 84%, respectively. The organic loading rate and HRT were reported as 8.9 kg BOD/ (m3d) and 6h, respectively.
