an ideal F:M balance.
The plant determined that
removal efficiencies were
highly stable when operat-ing
within the site-specific
acceptable range, and TOC
analysis was a more effec-tive
tool to maintain
this balance than typical
oxygen demand testing.
Additionally, the continu-ous
online data resulting
from TOC analysis allowed
the facility to rapidly adjust
streams and use the F:M
ratio for a more effective
process control by actively
ensuring the appropriate

the microbiology. This
allowed the plant to reduce Traditionally, measuring Biochemical Oxygen Demand helped determine whether wastewater treatment was effective.
