WHAT IS TDS?

Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water. TDS, which is based on conductivity, is expressed in parts per million (ppm) or milligrams per liter(mg/L). TDS includes any inorganic element present other than the pure water molecule (H2O) and suspended solids.
TDS affects everything that consumes, lives in or uses water, from fish and plants to plumbing and laboratories.
For people, the lower the TDS level in the water you drink, the more efficiently your body's cells are hydrated. The higher the TDS level in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the
absorption of water.
The U. S.EPA'S Maximum Contaminant Levels of TDS for human consumption is 500ppm.
