Steady-State Anaerobic Co-Digestion of Aqueous Condensate From Municipal Sludge Pyrolysis.

ABSTRACT: Anaerobic digestion (AD) of condensate or aqueous pyrolysis liquid (APL) derived from municipal wastewater solids was successfully achieved both as a sole substrate and as a co-digestate with synthetic sludge, overcoming toxicity challenges previously associated with APL degradation. Key strategies that enhanced APL conversion to methane included optimizing the solids retention time (SRT) and organic loading rate (OLR) to mitigate APL toxicity, using an acclimated inoculum, and employing APL ozonation prior to digestion. Gas chromatography-mass spectrometry analysis confirmed APL constituents were removed in the process. Inoculum biomass from an industrial waste digester (IB) exhibited better performance in APL degradation compared to inoculum from a municipal digester (MB). APL ozonation
