3 High-rate anaerobic processes for agro-food wastewater treatment: recent trends and advancements

High-rate anaerobic processes (HRAnPs) appear to be a promising technology for agro-food wastewaters (AFWWs) treatment in terms of chemical oxygen demand and pollutant removal with a potential of energy savings or even energy-positive scenarios. Various configurations of HRAnPs for AFWWs treatment have been used in laboratory-, pilot-, and commercial-scale applications. This chapter discusses the performance of prevalent HRAnPs in the treatment …
