Total dissolved solids (TDS) refer to what?

Total dissolved solids (TDS) refer to all dissolved solids in a water sample, which encompasses a variety of substances, including salts, minerals, and organic matter that are present in water in molecular or ionic form. This measurement is crucial in understanding water quality and its potential impact on aquatic life, human health, and various water treatment processes.

Measuring TDS is important for several reasons: it can influence the physical properties of water, affect the water's taste, and indicate the water's suitability for aquatic organisms or irrigation. High TDS levels can also signal the presence of pollutants, which can be harmful to both the environment and human health. Thus, a comprehensive understanding of TDS is essential in the context of wastewater treatment and ensuring treated water meets regulatory standards for safe discharge or reuse.
