Abstract : The various anaerobic processes have specific advantages and disadvantages associated with each. It is instructive to compare typical organic loading ranges of anaerobic processes with respect to conventional aerobic treatment to gain a perspective on these applications. Typical loadings of several common biological processes are compared in Table 9, where all systems are designed for 70 to 95 percent removal of biodegradable organics. When properly applied, all anaerobic processes have the potential to be net producers of energy, as opposed to alternative stabilization processes, which are essentially all net consumers of energy. Table 10 summarizes the preferred application of the anaerobic processes discussed. For all practical purposes, the energy consumption of all these processes, except the expanded SMAR, is a function of the volume of flow treated. However,for the expanded bed SMAR, energy consumption is a function of organic loadings. Anaerobic contact and conventional anaerobic processes are favorable for high-strength wastes.
