What does TDS stand for in the context of water quality?

Total dissolved solids (TDS) is a significant parameter in water quality analysis that refers to the combined concentration of all inorganic and organic substances contained in a liquid. These solids can include salts, minerals, and metals that are dissolved in water. TDS is typically expressed in milligrams per liter (mg/L) and provides insight into the overall quality of water, helping to indicate whether it is suitable for drinking, agriculture, or industrial processes.

Understanding TDS is crucial for steamfitters and professionals working with water systems, as high levels of dissolved solids can impact water's physical and chemical properties, potentially leading to issues such as scaling in pipes, reduced efficiency in heating systems, or adverse effects on equipment and processes. Assessing TDS helps ensure that water used in various applications meets necessary safety and quality standards, thereby helping to maintain the integrity of both the water supply and associated systems.
