Can I purify water in a microwave


Quote  |  Reply

Hi

I have half a dozen one and a half litre glass bottles (Ex V8 veggie juice) that I use as water bottles (I never use plastic for food or drink) I keep 3 bottles in the fridge and 3 on the kitchen window sill, in the hope that the sun will kill at least some of the chlorine and other chemicals that the govt puts in the water.

What I would like to know is If I were to nuke (microwave) the full bottles for say 9 minutes or until boiling, would that remove any of the chemicles?

I could even drop a teabag in afterwards to put in some flavour

No.

Just drink the water.

^this. Who cares about crap in the water? If you're really concerned, go get a water filter that goes on the tap or one of the pitchers, they're not that expensive.

No, boiling it would actually just concentrate the chemicals.  Get a filter.  That is the only way to remove the chemicals.  Also, the cheap Brita and PUR filters and pitchers don't remove most chemicals.  I got a chlorine filter from crystal quest for about $25.  It lasts for a year so it was worth it.  I am currently saving up for a fluoride filter which is over $100.

Boiling water is an effective way of killing bacteria etc that might be in the water.  It won't work to remove chlorine. 

adolphs is right--you can actually end up increasing the concentration of chlorine in your water.  Because some of the water is lost as steam, but the chlorine remains, you end up with the same amount of chlorine in a smaller volume of water. 

The best way that I've found to get rid of the chlorine/ammonia combo that our district uses to purify tap water is an activated charcoal filter.  I use a large Greenway filter, as Brita etc didn't work well enough. 

The system I use (Greenway from Canadian Tire) goes right onto a standard water cooler.  The big cooler bottle is in two parts with a cylinder type filter in between.  I pour tap water in the top, it goes through the filter and is stored in the bottom and the cooler tank.  I pay about $35 (Canadian) for a new filter every four months (about 600 litres worth of water).

Bonus--no water jugs taking up space in my fridge. :)

 

Chlorine evaporates pretty easily, as evidenced by the chlorine levels in my swimming pool.  :D  In fact, one of the ways to dechlorinate water for fish tanks is to just set it out for a few days.

As for other chemicals, a good filter would get rid of most of them.  Setting your water in the sun invites algae growth (again, swimming pools and fish tanks).  Boiling water or high intensity UV light will kill germs, but not remove chemicals (and the sun isn't high intensity enough).

That's what I was thinking.

I wouldn't want to breathe in the airborne chlorine that resulted from this, though.  I got filters for my sink and shower head to limit our exposure to airborne chlorine.

I thought fluoride was good for one's teeth?

Boiling does not concentrate chlorine it removes it. The chlorine in the water goes away after about 24 hours at room temperature too. Boiling water removes any compound that has a boiling point lower than 100 centigrade and it kills microorganisms, most bacteria die at 60 centigrade.

There are differing views on that, but all the research I have done indicates that in order for fluoride to benefit your teeth, you need to keep it on your teeth/in your mouth for a while, although there is a lot of evidence the fluoride actually does nothing for your teeth and may actually cause more damage to them (dental fluorosis).  Anyway, even if it is beneficial, the low levels in water and just drinking it does little for your teeth, but ingesting it is actually quite harmful to the body, causing cancer, osteoporosis, and many other problems, especially when combined with all the other chemicals that are in our bodies. 

The whole fluoride in water thing is a scam perpetrated by manufacturers as a way to get rid of industrial waste without having to pay for it.  Fluoride is a by-product of atomic bombs.  Instead of properly disposing of it, they get the city to buy it from them and dump it into our water supply.  More and more places are moving away from this practice but unfortunately it's still pretty common in the US.

Chlorine doesn't disappear magically.  When it evaporates, then you just breathe it in, which is just as toxic, if not more so, than drinking it.

I live in a  area of the country where only some people have fluorinated water and I can tell you that it does REALLY help with dental health

Chlorine has been replaced by chloramine in many areas. It's a combination of chlorine + ammonia, which doesn't dissipate as easily.  It's a good idea to filter it out.

Maybe people in non-fluoridated areas have poorer dental hygiene habits.  I imagine that districts that don't add fluoride are rural areas with lower-income people who don't visit the dentist as regularly, aren't as savvy about brushing & flossing, etc.

Topical fluoride (in toothpaste) is the best way to get fluoride.  Fluoride in water really only benefits children too young to brush properly.  But they can get their fluoride from tea instead, which is actually higher in fluoride than tap water.

Doubtful.  Studies have shown that dental health increases with hygiene and good dentistry, not fluoride.  Most countries in Europe do not fluoridate their water and they have experienced similar advances in dental health as the US.  Correlation does not equal causation.

Is It Possible to Go Natural?
The side effects of allergy medications keep some people from using them. Natural remedies can be a great alternative, but some are more effective than others.
