Abstract

A critical review of the different hydrodynamic mathematical models available for nonideal flow configurations of both low-rate and high-rate anaerobic reactors is presented, including upflow anaerobic sludge blanket reactors, anaerobic fluidized bed reactors, anaerobic biofilters, wet and dry digesters. The review highlights the role of mathematical modeling on design and operational optimization of organic waste and wastewater treatment plants. For each reactor configuration the following approaches, proposed by various authors, are presented and compared: (a) plug flow model, (b) tank in series model, (c) dispersion model, and (d) computational fluid dynamic model. The review gives a general overview on mathematical modeling of anaerobic nonideal plug-flow reactors and compares different models indicating the advantages and disadvantages to apply them for different reactor type.
