Hello,
I maintain that there are many cartridges to remineralize water (you just have to type "remineralization cartridge" in google and you will find)

In addition, the water leaving the menbrane contains almost no more minerals which are essential for good health (not just salt).

And I would like to know what a complete device is as well as the difference with equipment used in aquarium keeping.

New test

Tap water (unfiltered)
pH = 7.6 (ideal)
Chlorine = 1.6 (there are)

Water from my fountain (filtered)
pH = 7.4 (barely noticeable difference, or uneven reagent dosage?)
Chlorine = 1.3 (same remark as for pH)


hi Citro,
I don't really know what is the composition of your filter cartridge ...., but I hope it is not activated carbon .. !! ??
because a similar result on chlorine is absolutely not consistent with activated carbon, which has a very good efficiency on this subject .. !!

but this filter is presented in "double action" (sediment + chlorine) ..., very perplexed in view of this result before / after .............


@ Justemilieu ....;

I have already spoken enough about it ..., I will not repeat myself every time ...
I said, after all .. "everyone has their own ideas" ... and everyone believes what he wants .......
if you want to know more, more precisely, you just have to look for the info with the specialists of the question .....
(not aquaristic ..)


@ fabio.gel;

be careful not to generalize a very specific case, especially when you do not know the type of device, its exact composition, its quality and performance rate, its use ....
because "bad" devices ..., there are ... (counterfeit, low-end Chinese device ...), but without denying the case presented here and its impacts ....., it is not reasonable to 'thus judging a type of device in general ....... !!
(it is already not normal to have such a low pH at the output of the reverse osmosis unit ... !!!, therefore, there is a lot of doubt about the operation or the quality of this device ... but not to question all devices of this type! )

cordially


Hi little pierrot

I did an interesting test
So I disconnected the pipe that connects the last of the filters to the osmotic membrane in order to check the PH of the water at the bottom of the three filters.
The result is 7,17 before the membrane.

So I think that with any osmosis water must still be pretty acid at the outlet.

Bonne fin de journée

Fabio

therefore, not suitable for daily domestic use ....

pH at 7.17 = neutral and impeccable pH !!
so I don't understand why after the membrane it would become "damn acid".... ?????

A pierrot is small, but a little pierrot is even smaller.
But that doesn't mean anything, it's like peppercorns, it can be very small and sting very hard : Cheesy:
I have to get treatment, I fixate on the charming first name of pierrot :D

Hi little pierrot

This is only a statement on the result of ph at home.
But it seems to me that the membrane allows only elements of a size less than or equal to a micron to pass through so it is likely that the minerals do not pass this barrier resulting in less mineralized water (hence the pH between 5 and 6).

Bonjour,

hi fabio.gel,

heuuuu ..., I'm wondering if you would not confuse "pH" and "° Th" ....
pH being the Hydrogen potential (acid-base) and ° Th being the hardness of the water ...

because if you speak of "minerality" of water, it corresponds rather to ° Th, which at the outlet of the osmosis unit is indeed less than 5 ° Th .. (very weakly mineralized, without being demineralized ..)

but concerning the pH, it is not the osmosis unit which will significantly reduce it ...

Also, the porosity of a reverse osmosis membrane is not the size of a micron, but of the 10th of nano, therefore of the 10 thousandth of a micron !!!
water only passes through it in the molecular state ....
this is why there is almost nothing left in the RO water, apart from some dissolved substances and some minerals in very small quantities.

Exact little pierrot

By cons it is the PH test that I do with this device.

By cons my installer can not explain why on some installation the PH is reduced significantly !!!.

As an aside, do you prefer weakly or strongly mineralized water? (there are two bell sounds on the internet)

Have a good day

I don't have to say either ...

oh well yes but that is valid for everything! .., we read everything and its opposite, and also anything on the net .., but that's also what helps to move forward when we take the trouble to search ...

Personally, I have already explained it many times, I accept and trust what I hear from researchers and scientists specializing in water, who demonstrate that it is necessary to consume (in the usual way) weakly mineralized water. .! , and that the opposite (except in special and occasional cases!) is useless apart from fouling the body a little more than it already is, while greatly reducing the detoxifying action of the water which is vital to him ....

but as I always say ... "everyone believes what he wants .."!

Hello, Pti pierrot,
I read your last answer ... which I do not dispute (I have not analyzed the history of weakly mineralized water.
This morning, I researched the pangas (a fish)
And I found a person who was talking about the same thing as me.
I quote:
You have of course the possibility of buying bottled water, there are three categories: table water, spring water and natural mineral water. You have to alternate brands to be sure you have all the necessary inputs such as trace elements, sodium, potassium or calcium ... essential for energy needs. We remind you that the body requires between 1 liter and 1,5 liters per day. Very important during heat waves: consumption easily doubles and it is a vital gesture.

I should have copied the source of this info, I am wrong.
But this answer seems logical to me (personal opinion)
Now, I can tell you that I like your interventions, because it seems to me that you are of the trade.
