Abstract:
1. A process comprising: adding an aqueous waste stream comprising metabolizable components to a growth vessel containing at least one bacterial culture, at a first flow rate; allowing the bacteria of the at least one bacterial culture to grow in the growth vessel by metabolizing at least a portion of the metabolizable components of the aqueous waste stream, thereby forming a bacterial suspension in an aqueous bulk liquid, wherein the aqueous bulk liquid is depleted of metabolizable components relative to the aqueous waste stream; separating a portion of the bacterial suspension from the aqueous bulk liquid, thereby forming a bacterial mass; removing the bacterial mass at a second flow rate; removing a portion of the aqueous bulk liquid at a third flow rate, wherein the aqueous bulk liquid is substantially free of total suspended solids; adjusting the second flow rate to provide a MCRT of the bacteria of no more than about 8 days; and drying the removed bacterial mass within a time period whereby MWRT−MCRT≦about 2 days.
