TDS stands for Total Dissolved Solids. It is a measure of the concentration of inorganic and organic
substances that are present in a liquid solution, typically water. TDS includes a wide range of dissolved
substances such as minerals, salts, metals, and other organic compounds. TDS is typically measured in
parts per million (ppm) or milligrams per liter (mg/L) and can be determined using a variety of methods such as gravimetry, conductivity, or refractometry. High levels of TDS in drinking water can affect the taste, odor, and overall quality of the water. TDS can also impact the suitability of groundwater for certain microbiological degradation processes.
