No clue what you're asking?
Should be clear enough. I'm asking if you meant to say:
"I'm more or less confident that the bottled water we drink here is of the mineral free distilled variety"
i.e. there are no minerals in it because it's been distilled.
I said and meant....."is not of the mineral free distilled variety"..... Then I go on to ask if the purifying process used does anything to deplete minerals.....etc. If the water was distilled we wouldn't have a thread as it would be clear already that there are no minerals in what we drink. There is also some indication that RO removes some minerals but we have an engineer on here (Terry) who has indicated in a previous thread that the big bottle (18L) companies who have "reverse osmosis" on their labels really don't use true RO.
I still don't think any distilling is used at all with the exception of those products for special use that should be clearly marked as "distilled water". Drinking only distilled water over time can have very bad effects on the body as is clear when searching for the term.
Steve G mentions the big name brands who "have invested millions" to purify water, but still not specific if this purifying process removes minerals present or what process they use. I'll try to do some more searching to find anything more definitive but so far I can find nothing. Perhaps someone in the water business will surface later on. Pete
Sorry for my misunderstanding
Table 1 at http://www.who.int/water_sanitation_hea ... chap12.pdf
shows TDS (total dissolved solids)
for many types of drinking water in Thailand. I understand that it correlates broadly to the quality of water for drinking.
I tested the water in my fridge and I got:
Namthip - 120 ppm
Crystal - 80 pm
So they come out in line with the bottled purified waters in the table. Similar to Bangkok tap water, which is correct if most bottled water is made from tap water.
I tested Pranburi Water Authority water and it has TDS of 1400 at the point where it enters my storage tank.
Anyway, I agree that I hope they don't sell us distilled water (unless they replace removed minerals) because apart from missing minerals (which you should get anyway from a balanced diet), there seem a lot of other nasties:
The below and lots of other nasties at http://www.who.int/water_sanitation_hea ... chap12.pdf
"It has been adequately demonstrated that consuming water of low mineral content has a negative effect on
"Regular intake of low-mineral content water could be associated with the progressive evolution of the changes
discussed above, possibly without manifestation of symptoms or causal symptoms over the years. Nevertheless,
severe acute damage, such as hyponatremic shock or delirium, may occur following intense physical efforts and
ingestion of several litres of low-mineral water."
- 'hyponatremic shock' is water intoxication and can be fatal, I'm sure you've read elsewhere before.
