Evaluation of anaerobic sludge digestion in combination with thermal alkaline process as pre- and post-treatment: Impacts on energy, economic, and CO2 footprint balances.

To determine whether wastewater treatment plants (WWTPs) should use the thermal hydrolysis process (THP) or the thermal alkaline process (TAP) as sludge pretreatment or posttreatment methods, this study was conducted on five WWTPs implementing THP/TA…
