Total Dissolved Solids

Total Dissolved Solids




Total Dissolved Solids(TDS) are all inorganic and organic substances contained in water in molecular, ionized, or suspended form. These solids must survive filtration through a sieve with 2 micrometer pores to be considered TDS. If not they are considered Total Suspended Solids. Common components of TDS include calcium, phosphates, nitrates, sodium, potassium and chloride. TDS are an indicator of the presence of a broad array of chemical contaminants.
