Wastewater treatment plant operators know that accurate measurement of suspended solids is critical to maintaining the proper level of activated sludge within an aeration basin. Adjustments to the return and removal rates of the activated sludge can help the efficiency of the basin in reducing the COD and BOD of the mixed liquor. Monitoring suspended solids in the biosolids processing stages of industrial wastewater treatment plants may improve dewatering performance, thus saving money through accurate polymer addition and reduction of time-consuming laboratory analysis. Suspended solids sensors designed for tough industrial applications can help plants with their most cost-intensive processes, including sludge wasting, thickening, dewatering and DAF applications.
