This test reports presents both bench and field-test results of 11 instruments from 6 manufacturers of online chlorine residual analyzer systems utilizing amperometric, colorimetric and polarographic technologies.  Both free and total chlorine analyzers for water and wastewater treatment applications were field-tested at a calibration range of 0-2 mg/L.  

Bench Tests 

Bench tests were conducted in an environmentally controlled chamber in which one parameter at a time was changed to ascertain the individual effect and to evaluate accuracy related measurements and the effects of commonly encountered interferences.  Bench tests included warm-up effects; reagent addition; flow sensitivity; loss of sample; signal noise; calibration; drift; reproducibility; dead band; detection limit; response time; recovery time; ambient temperature effects; sample temperature effects and interference.

 

Field Tests 

Field tests consisted of operating the free chlorine residual analyzers at an operating water treatment plant and the total residual chlorine analyzers at a wastewater treatment plant for a 45-day period. Laboratory conformance measurements were performed twice per day to compare with analyzer output to demonstrate the instrument&##39;s overall accuracy when subjected to many simultaneously changing parameters as experienced in real-time monitoring conditions.  Field test results can can provide information regarding instrument design, operation and maintenance requirements which influence the performance of the instruments in field applications.
