Calculate Total Solids in Wastewater

Up-to-date and precise knowledge of Total Solids (TS) is a key driver for operational efficiency of wastewater treatment facilities. Total Solids in wastewater reflect the conditions in the tanks, define the optimal dosing of polymer for dewatering and are important for trucking and invoicing of biosolids.

Typical measurement points for Total Solids (rsp. Total Suspended Solids, TSS) in wastewater treatment facilities are primary sludge (1), activated sludge (2), digested sludge (3) and dewatered sludge (4).

The cost of sludge concentration and disposal has one of the largest impacts on wastewater treatment plants. Optimal dosage of polymer and precise adjustment and control of dewatering equipment (e.g. belt press, centrifuge) is crucial for cost efficient operation. The HC103 moisture analyzer can be used to support efficient and fast determination of solids in wastewater.

With the example of dewatered sludge it is demonstrated how easy and fast you get results for your sample. A correlation of the moisture analyzer results versus the drying oven method is done proving that the HC103 moisture analyzers provides good repeatability and results matching the results from the official method drying oven.
