In the daily work of water quality testing, the question arises. Is the TDS of water the total hardness of water? Some people even think that TDS is the total hardness of water.

It seems that the public's understanding of TDS and water hardness is still relatively small.

So, what is TDS and what is water hardness?

TDS: (Total Dissolved Solids, referred to as TDS) dissolved as well as the total amount of solid waste, the test unit of work for mg / liter, indicating that 1 liter of water to join how many dissolved industrial solids dissolved through the milligrams. the higher the value of the TDS, indicating that the water contains mainly dissolved matter more. Total dissolved formation of solids refers to the water to carry out all as the total amount of solute, including some inorganic and organic matter to analyze the content of both.

Water hardness:Refers to the content of Ca2+ and Mg2+ ions in water. Used to characterize the content of calcium and magnesium ions in water.

TDS mainly reflects the concentration of Ca2+, Mg2+, Na+, K+ and other ions in water

Water hardness study can mainly reflect is the content of Ca2+, Mg2+ ions

There is a correlation between the two, but a high TDS value does not mean that the water hardness will be high, for example, by adding sodium, potassium, salt, carbonate plasma to the water, the TDS value will increase,geiger counter radiation detector and have no effect on the hardness.

The amount of total dissolved solids is directly related to the taste of drinking water.

Drinking water with a TDS < 1000MG/L is easy to accept, the flavor is too poor to affect the taste, and conversely too low becomes bland and tasteless. Small TDS does not mean good water quality, and large TDS does not mean poor water quality. Qualified drinking water must meet microbiological indicators, toxicological indicators, sensory indicators, organoleptic indicators, and general chemical and radiological indicators. Healthy, tds meterclean drinking water must not contain pathogenic microorganisms, chemical substances and radioactive substances, must not jeopardize human health, with good sensory characteristics.

The relationship between drinking water hardness and human health

Calcium and magnesium ions are the human body needs every day we need essential nutrients, if the water has a certain hardness, through their own drinking water problems can be carried out to replenish with a certain amount of calcium and magnesium ions. If it is a person who takes soft water for a long time,dosimeter vs geiger counter also need the enterprise through learning other important ways as well as supplementation. But the water hardness is too high and too low is not good, because the water hardness and some related diseases have close cooperation relationship. In areas with higher water hardness, the incidence of cardiovascular system diseases in the population is lower, but the incidence of kidney stones increases with higher water hardness.
