“…A recent study reports an improved methane yield and COD removal efficiency when supplementation with micronutrients such as Fe, Co, Cu, and Ni is carried out. As noted, the addition of 2 ppm of Co, Cu, and Ni and 50 ppm of Fe resulted in a 42.3% increase in the specific methane yield compared to the control [124]. (1) -as L-CH 4 /g-COD removed ; (2) -as total COD; (3) -as settled COD; (4) -m 3 -CH 4 /kg-COD applied ; Nd-no data.…”

Brewery (BW) and dairy (DW) wastewater are two types of agro-industrial wastewater that are generated in large amounts and, therefore, should be treated effectively and in an environmentally beneficial manner. Both these wastewater types are characterized by a high COD, BOD5, and nutrient content, and conventional wastewater treatment methods such as an activated sludge process may prove to be inefficient due to the possibility of foaming, large biomass production, low activity at low temperatures, and risk of overloading the reactor with a load of organic pollutants. In the context of the described difficulties, anaerobic processes seem to be the best alternative. An interesting research area is the co-digestion of these wastewaters. However, this research direction, so far, has not been frequently reported. Given the gap in the current knowledge, this literature review aims to assess the possibility of BW and DW digestion in anaerobic reactors and provide up-to-date data on the post-treatment methods of effluent generated after the anaerobic digestion process. Despite numerous advantages, anaerobic treatment often requires post-effluent treatment to complete the treatment cycle.
