Transcription of TOTAL DISSOLVED SOLIDS MEASUREMENT - IC Controls
{{id}} {{{paragraph}}}
TOTAL DISSOLVED SolidsDefinition: TOTAL DISSOLVED SOLIDS (TDS) is ameasure of the sum of all inorganic and organicsubstances in a liquid in molecular, ionized ormicro-granular colloidal suspended form. Thesolids must be small enough to survive filtrationthrough a sieve the size of two micrometer. TDS SOLIDS are normally found in all freshwatersystems. Major applications of TDS are: at lowlevels the study of water quality for streams, rivers,lakes, potable water taste, and at high levels thecontrol of scale in recirculating water systems. It isa quality indicator for drinking water and is ageneral measure of the presence of chemicals. Inseawater RO desalination , TDS provides a way ofcomparing the feed with the permeate quality thatis relevant to drinking water taste standards.
seawater RO desalination, TDS provides a way of comparing the feed with the permeate quality that is relevant to drinking water taste standards. Where does TDS come from? TDS in surface waters come from the solvent action of water in contact with minerals in the earth, agricultural and residential runoff, leaching
