Explain TDS (hard and soft water)

Question

Accepted Answer

TDS stands for Total Dissolved Solids, which measures the combined content of all inorganic and organic substances in water.

TDS is a measure of the total amount of dissolved solids in water, including minerals, salts, and organic matter.
Hard water has a high TDS level due to the presence of minerals like calcium and magnesium, while soft water has a lower TDS level.
TDS is typically measured in parts per million (ppm) or milligrams per liter (mg/L).
High TDS levels can affect the taste and quality of water, as well as impact the performance of water treatment systems.
Examples of TDS sources include natural mineral deposits, agricultural runoff, and industrial wastewater.
