Role of Biogas Recirculation in Enhancing Petrochemical Wastewater Treatment Efficiency of Continuous Stirred Tank Reactor

Although the co-digestion of petrochemical wastewater (PWW) with activated manure (AM) is providing an improved production of bio-methane, still several researches are going on how the bio-methane generation and COD removal efficiency can be maximized? Therefore, a question strikes our research moti...
