Impact of THP on digestion
• THP makes organic matter more readily available for the anaerobic digestion
• Better VSR
• Higher Biogas yield
• Lower viscosity – usually digesters are therefore operated at higher DS concentration to increase capacity
Impact of THP on digestion
• This also means more gas is produced per digester volume – the gas has less time to escape from the sludge
