scada system scope items include extension of scada communications from the existing influent building rtu to the new lime skid equipment, extension of ph probe cable from the scada panel to the influent stream
, and extension of ph probe cable from the clarifier rtu to the influent channel following the fine screen filters.
Organic loading rate= COD of the influent stream
i](t): excess hydrogen ion concentration in the influent stream
Thermal conditioning reduces solids that require further processing by solubilizing 30 to 40 percent of the volatile solids and COD in the influent stream
ferric chloride has been added to the influent stream
and consequently can be found in the sludge and cleanings.
The concentrate stream, or brine, will contain the large majority of the salts from the influent stream
as well as about 15 percent of the influent water.
Without replacement of the media, the biofilter will not operate correctly, would introduce untreated gasses/odors from the WWTP influent stream
into the atmosphere and increase potential of nearby residential odor complaints.
A standard EPA-accepted or approved chemical oxygen demand (COD) test is required for EPA reporting, but a more rapid and mercury-free method is available for testing influent streams
when reporting is not required.
