The United Kingdom has seen a renewed interest in anaerobic digestion and in particular Advanced Digestion systems. The benefits claimed for these systems are many including increased biogas production, high pathogen kill to Treated and Enhanced Treated standards and better dewaterability of digested sludge to name a few.
This paper reviews performance of three Enzymic Hydrolysis plants operating in the UK and compares their relative performance to conventional digestion. Important parameters are identified to provide the designer of future plants with a basis for evaluating the expected performance compared with others systems on the market.
Performance of these plants in terms of biogas production, net power generation, pathogen reduction and sludge dewaterability improvement are reported.
