The RV portable water softeners (On-The-Go & FloPur are two brands) are filled with a resin. The resin collects calcium/magnesium. When resin is coated you clean the resin with a brine solution. Then the brine is rinsed away. (Open top,pour in box of table salt, let sit for 15-20 mins, gently rinse for 15 mins. Regen done)
In a large home system the added sodium content is minimal. There is 5 times more salt in a glass of milk than in a glass of softened water.
PH of water is only slightly raised by softening because sodium is alkaline.
Normal PH for drinking water.......6.5 to 8.5.
Softening only raises PH by .2 to .3 units
Milk has a PH of 6.2
We have used our portable for 7 yrs whenever in areas of hard water.
Keeps the WH from scaling up, keeps the faucets from scaling up, keeps the toilet bowl and inlet valve from scaling up. Great suds in shower and sink.
We drink it, bath in it, wash with it.
The only thing we don't do is make coffee with it. I would as I drink coffee black but GF likes 'cream' (non-dairy kind) and it doesn't mix. It just clumps.
