Non-invasive ILR sensor installation in a wastewater treatment plant

Continuous and efficient polymer dosing control to optimize sludge dewatering is critical in order to enable efficient operation of waste water filter belt presses. Currently, there are no measurement techniques available for in-line rheometry for continuous and efficient polymer dosing control to optimize sludge dewatering. The in-line rheology system was custom designed for a wastewater sludge dewatering application. The instrument is capable of measuring variation in rheological parameters of poly-dosed inflow sludge as a function of process parameters. A unique relationship between process parameters, yield stress in the pipeline just after dosing and the filtrate suspended solids concentration (TSS) was established. This technology can now be used for improving the efficiency of wastewater plants by reducing the amount of chemicals/polymers dosage and thereby reducing operating costs.
