Total Suspended Solids (TSS) testing is required for both National Pollutant Discharge Elimination System (NPDES) permit compliance and for many different wastewater treatment process control tests. Many wastewater operators perform this test either through in-house laboratories or in the field for process control. Further, the test is now being used for stormwater monitoring as well. However, the procedure is often performed incorrectly with steps omitted and a lack of quality control / quality assurance resulting in poor quality data. Many small wastewater plants are still using the centrifuge spin analysis method, which is inaccurate at best. However, instrumentation exists, both hand-held and in-basin probes for TSS measurements, and is being utilized by large and small wastewater plants alike.
This webcast will discuss the importance of TSS testing, instrumentation, and technique and application of data. During the webcast, speakers will provide a comprehensive review of the broad range of analysis methods (gravimetric, centrifuge spin, and meters), along with the advantages and disadvantages of each method. Process control decisions are only as good as the data they are based upon.
