It should be noted that the VSS measured includes other particulate organic matter in addition to biomass. Most wastewaters contain some amount of nonbiodegradable VSS and possibly influent VSS that may be degraded slowly in the biological reactor. These solids are included with biomass in the VSS measurement. Neverthele.. 2024. 1. 16.
