Reaction models for bio-oxidation using a sheet flow reactor with a fixed biological film similar to that used in plastic media trickling filtration are developed. The models utilize plug flow hydraulics and accept various descriptions of BOD removal kinetics including zero order, first order, retardant and concentration dependent mechanisms. Hydraulics, kinetics and film geometry are individually incorporated. System model equations are arranged into linear expressions which allow graphical determination of model applicability and rate constants from plots of experimental data. The design and operating characteristics of laboratory simulation equipment are presented. Simulation equipment consists of continuously fed inclined planes with effluent sedimentation and recirculation. Effluents can be fed from and returned to coldroom storage. Heating tapes control temperature above ambient levels. System location in a cold-room provides temperature control at below ambient levels.
