What are conductivity tests used to measure?

Conductivity tests are specifically designed to measure the ability of water to conduct an electrical current, which is closely related to the concentration of dissolved solids present in the water. When various salts and minerals dissolve in water, they break into ions, allowing the water to conduct electricity. Therefore, a higher conductivity reading typically indicates a higher concentration of these dissolved solids, such as salts or metals.

The relationship between conductivity and dissolved solids is important in wastewater management as it helps operators assess water quality and the effectiveness of treatment processes. For example, monitoring conductivity can indicate changes in pollution levels and can help in managing discharge limits and ensuring compliance with environmental regulations. Understanding conductivity can also assist in determining the efficiency of various treatment stages and the overall stability of the wastewater system.
