Water Classification

 

" Water Classifications , Based on Salinity (Total Dissolved Solids - TDS - parts per million ( ppm ) or
mgms / lit )"
-----------------------------------------------------------

Fresh water  --  Less than 1,000 ppm.
mild saline water -
  From 1,000 ppm to 3,000 ppm.
Moderately saline water -
   3,000 ppm to 10,000 ppm
Highly saline water -
  10,000 ppm to 35,000 ppm
SEA water contains -->  35,000 ppm
TDS, which is called SALINITY.
