Abstract: A hybrid bioreactor, combining an activated sludge process (ASP) and a rotating drum biofilter (RDB), was developed and evaluated for the treatment of volatile organic compounds (VOCs) in waste gas streams. The effects of ...

Abstract: A gravity drainage model was developed that included terms for cake resistance, filter resistance, and initial ponding. Laboratory scale batch drainage tests were performed at sludge volume loadings between 0.013 and 0.006 m

Abstract: An interactive microcomputer program referred to as runway exit design interactive model (REDIM) has been developed to optimally locate and design high‐speed runway exits at airports. The model uses kinematic equations to ...

Abstract: Steady-state models of nitrifying biofilms are developed taking into account the mass transfer of neutral and ionic species, electroneutrality, pH-dependent Monod kinetics, chemical equilibrium, and the presence of a ...

Abstract: The affect of nitrate concentration and reactor backwashing on biofilter performance is evaluated using a dynamic mathematical model of the biodegradation process of volatile organic compounds in a trickle bed biofilter ...
