Abstract: The sludge production and settleability have been estimated experimentally in a completely mixed biofilm-activated sludge reactor (hybrid reactor). A steady-state hybrid reactor was run at different stages of suspended ...

Abstract: A steady state mathematical model is developed for describing the completely mixed biofilm–activated sludge reactor (hybrid reactor). The model is derived by simultaneously considering Monod kinetics expressions and Fickian’s ...

Abstract: A direct and simple method is presented for the determination of sewer geometry of circular and noncircular shapes for partly full‐flowing conditions with the known variables being discharge, bed slope, and Mannings roughness ...
