Understanding TDS and Its Importance
What is TDS?
Total Dissolved Solids (TDS) refer to the total concentration of dissolved substances in water, including minerals, salts, and organic matter. TDS levels are typically measured in parts per million (ppm) or milligrams per liter (mg/L).
Why is TDS Important?
Monitoring TDS is crucial for various reasons:
– Health Concerns: High TDS levels can indicate poor water quality, affecting drinking water safety.
– Aquaculture and Hydroponics: Maintaining optimal TDS levels ensures healthy aquatic life and plant growth.
– Industrial Applications: Many industries require specific TDS levels for optimal processes.
