WTP‟s Limiting Component
First thing this water system can do to increase Component

(i.e., Production generally > Treatment during Pk.-hr conditions,
and Water level in Clearwell is typically dropping)
Pk.-hr of
Treatment
Pk.-hr
Production
CT = residual disinfectant Concentration x effective contact Time
T is based on pk.-hr of treatment and corresponding clearwell level
