| | I am looking for expertise on the monitoring of collection system H2S concentrations as they relate to the addition of Calcium Nitrate feeding into the pump stations of a countywide collection system. We currently feed and meter the Calcium Nitrate and check the effectiveness of the odor reduction by monitoring the H2S levels downstream of the injection point using portable air quality meters lowered in the sewer line. Is this the best way to monitor the effectiveness of the Calcium Nitrate or are other air quality parameters or wastewater quality parameters more useful and accurate? |
