2. A CSTR (10 L) with Gordonia bacterial cells is being used to treat hazardous waste containing the NONCONSERVATIVE groundwater contaminant RDX. The concentration of RDX going into the reactor is 0.22 mg/L and the RDX decay coefficient with this bacterial strain (K) is 5 min¹. The flow rate of groundwater going into the reactor is the same as the flow rate of the treated water (2.5 L per day) leaving the reactor. Assuming STEADY STATE conditions, determine the RDX concentration (in ng/L to three significant figures) in the bioreactor effluent (solution leaving the reactor).

Transcribed Image Text:2. A CSTR (10 L) with Gordonia bacterial cells is being used to treat hazardous waste containing the
NONCONSERVATIVE groundwater contaminant RDX. The concentration of RDX going into the
reactor is 0.22 mg/L and the RDX decay coefficient with this bacterial strain (K) is 5 min¹. The flow rate
of groundwater going into the reactor is the same as the flow rate of the treated water (2.5 L per day)
leaving the reactor. Assuming STEADY STATE conditions, determine the RDX concentration (in ng/L
