TDS and Conductivity:TDS and conductivity are important water quality parameters that are often used to assess the suitability of water for different uses. TDS is a measure of the total dissolved solids in water, while conductivity is a measure of the ability of water to conduct an electrical current. Both parameters are affected by the presence of dissolved minerals in water.High TDS and conductivity levels can indicate the presence of pollutants such as heavy metals or organic matter. TDS and conductivity can also be used to monitor the efficiency of water treatment processes.
