Biomass retention
WebMar 27, 2024 · During calcination, temperature and biomass retention time play a critical role in the formation of the resulting carbon material morphology and structure. WebAug 8, 2003 · There are two significant retention times in an anaerobic digester. These are solids retention time (SRT) and hydraulic retention time (HRT). The SRT is the average time that bacteria (solids) are in the anaerobic digester. The HRT is the time that the wastewater or sludge is in the anaerobic digester.
