What is tds mean?

TDS stands for Total Dissolved Solids, which is a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular, ionized, or micro-granular suspended form. These substances can include minerals, salts, metals, cations, anions, and other organic matter.

TDS is commonly measured in parts per million (ppm) or milligrams per liter (mg/L) and is an important parameter in determining the quality of water. It is often used as an indicator of water purity and can affect the taste, odor, and overall suitability of water for consumption, irrigation, industrial processes, and other uses.

High levels of TDS in water can indicate contamination or the presence of harmful substances, while low levels may indicate a lack of essential minerals. It is important to regularly monitor and maintain TDS levels in water to ensure it meets safety and quality standards.
