According to characteristics of microbial growth, anaerobic treatment processes can be classified in two major groups: fixed-film and suspended growth. In this study, operational conditions for both fixed-film (Downflow Stationary Fixed Film, DSFF and Upflow Anaerobic Filter, UAF) and suspended growth (Thermophilic Anaerobic Contact Reactor, TACR) model anaerobic reactors are presented and chemical oxygen demand (COD) removal efficiencies of these systems are compared.
