Water softener

[Sunflower]

Hello everyone.
I just bought a water softener (not at Culligan and other hotels comerçants ...), because of the high rate of limestone present in the water of the region.
Watching very carefully our water consumption, I wondered what to do with the fifty liters of water that normally go to the sewer during regeneration (all 5m3 treated water).
What exactly does this water contain?
If anyone can enlighten my lantern ...

Hello,

1 m3 processed for 5 m3 rejects?
is it "pure" drinking water?

Hello

The bottle around the resin contains brine
The brine initially contains dissolved sodium chloride (salt)
It is a solution that contains Cl (chloride) ions and Na (sodium) ions
During the softening phase of the sanitary water, through the resin, the Ca (Calcium) ion is replaced by the Sodium ion, the carbonate ion remains in the water.
So softened water is a solution of sodium carbonate
As for the brine, it contains only calcium chloride just before the regeneration.

Ok thanks for the information.
This means that during the regeneration, the softener rinses and evacuates a water heavily loaded with limestone? So no danger, if I water the garden with this water?

Limestone is calcium carbonate
What the water evacuated during rinsing is calcium chloride (salty taste) + impurities that could have attached to the resin
I can not tell you if there is any danger for watering, but it is likely that chloride is the most active product.

I'm going to do some tests ... on weeds first.
I'll keep you updated as soon as possible.

I'm doing a little post-digging ... how are your weeds doing?

[Sunflower]

Hey pierre.
In fact the softener is still in its box, I lack of time to install it ...
And the weeds are still there.

Well !

You really have to be overwhelmed ...

Well, well if anyone knows if we can water with this water cleaning, wave.
