The Eva fountain and the tds and th of the water

About the Eva filter:

The objective of the EVA fountain is not to reduce the limestone of your water (combination of calcium and magnesium). Only an osmosis at this functionality, with the disadvantage of withdrawing the minerals your body needs. To know the filtered elements and the results of water analyzes, fontaine-a-gravite.com provides you EVA analysis table

Some consumption recommendations: 

On a daily basis, there are some simple rules of consumption and use of tap water:

- Let the water run before consuming it when it stagnated in the pipes, from a few seconds to two minutes (in the event of prolonged stagnation, after several days of absence, for example);

- Use water from the cold water network for drink, preparation or cooking food: a high temperature can promote the transfer in the water of metals which constitute the pipes and the degradation of bacteriological quality;

- Leave the tap water in an open carafe for a few hours in the refrigerator to eliminate a possible taste of chlorine.

In the absence of specific instructions from the distribution manager, the mayor or the ARS (or possibly the doctor for infants), tap water can be consumed without risk.

The hardness of the water:

corresponds to the calcium and magnesium content naturally present in water. It is measured in mg of calcium carbonate per liter or in PPM / liter. If your water contains less than 60 ppm/l, your water is considered very soft.

Qualification	° F	MG/L CACO3
Very soft water	0 to 7	0 to 70
Pure water	7 to 15	70 to 150
Moderately hard water	15 to 25	150 to 250
Fairly hard water	25 to 35	250 to 350
Hard water	35 and more	350 and more

 

PPM (part per million)

1 ppm = 1mg/l

1 ° F (French) = 10 ppm

1 ° F = TH

The TDS* express all of the minerals dissolved in water, salts, metals, cations or anion, including any element present in water other than H2O molecules, including the solid suspended elements. The measurement is expressed in PPM.

TDS level (milligrams per liters)	Evaluation
Less than 300	Excellent
300 - 600	Good
600 - 900	fair
900 - 1200	Weak
Over 1200	Unacceptable

 

*Trade TDS testers do not have reliability, results of analyzes made by an approved laboratory Cofrac

The WHO recommends the drink of natural freshwater so little mineralized. On the other hand, it strongly advises against the consumption of softened water (water softener), because it has too many sodium ions which are harmful for health, especially for people with cardiovascular conditions.
