Optimization of Two-Stage and Single-Stage Anaerobic Reactors Treating Cheese Whey

Abstract

The objective of this research is to compare and evaluate the methane production from cheese whey in single-stage and two-stage anaerobic treatment processes. Single stage-reactor was operated in a pilot-scale batch reactor while two-stage reactor was operated in batch-dilution and semi-continuously. Reactors were loaded with cheese whey with an chemical oxygen demand (COD) of about 38.61 g/L. Single stage system was operated at 35°C with a hydraulic retention time (HRT) of 15, 10, 7 and 4 days; respectively. The maximum methane production in the single-stage reactor was obtained at 3.86 gCOD/L.d organic loading rate (OLR) with 10 days HRT being about 0.39 L CH₄ /L_reactor/g COD_deg.d; respectively. The results indicated that the use of a two-stage process for anaerobic treatment of cheese whey resulted in 4 fold higher methane yield compared to single-stage reactor system allowing better control of the acidogenic and methanogenic phases.
