Total Dissolved Solids (TDS) Measurement
Courtesy of IC Controls Ltd.
Definition
Total Dissolved Solids (TDS) is a measure of the sum of all inorganic and organic substances in a liquid in molecular, ionized or micro-granular colloidal suspended form. The solids must be small enough to survive filtration through a sieve the size of two micrometer. TDS solids are normally found in all freshwater systems. Major applications of TDS are: at low levels the study of water quality for streams, rivers, lakes, potable water taste, and at high levels the control of scale in recirculating water systems. It is a quality indicator for drinking water and is a general measure of the presence of chemicals. In seawater RO desalination, TDS provides a way of comparing the feed with the permeate quality that is relevant to drinking water taste standards.
