Total suspended solids (TSS) and ammonia (NH4) on-line meters were evaluated at the San Jose/Santa Clara Water Pollution Control Plant in seven streams. Three TSS meters were tested in five locations. The same TSS meter was recommended to be used for the activated sludge effluent and the subnatant of the dissolved air flotation tanks, in which the meter did not measure precisely TSS under normal operating conditions but was able to capture sudden increase. Only one of the two NH4 meters tested in the mixed liquor was recommended for measuring concentration greater than 2 mgNH4-N/L. An ex-situ analyzer was also evaluated for low NH4 concentration but was found to perform not as well as claimed by the vendor. This study highlights that due to plant-specific parameters, the field evaluation of on-line sensors is a required step prior to permanent installation.
