Abstract

The present study explores the use of capacitance-voltage measurements to detect and estimate the number of total dissolved solids (TDS) in water suspensions. With the application of the electric field, the suspended solids get polarized. The generated polarization enables their electrical traits and affects the electrical field uniformity. This has been translated into a change in the suspension effective capacitance value. It has been observed that the effective-capacitance suspension increases with higher TDS concentrations. To electrically estimate the count of TDS in water suspensions, a calibration curve has been generated with the use of deionized water to de-embed the effect of the suspended media. The curve correlates the TDS count with the change in capacitance and has been used to construct a closed formula. The proposed approach has been validated using conventional meters. The estimated and measured concentrations corroborated well with each other. The capacitance-voltage method can detect and quantify lower and higher ranges than those of conductivity base meters.
