Well I can't say exactly how soon it is coming, but the technology has been developed!
It's a small awesome little UV ray device you can install into your taps or pipes to instantly disinfect water to make it safe for drinking!
Technology is the fucking best.
Check it out.
why is it nonsense that UV technology can kill bacteria and viruses and micro-organisms? It kills anything living...
I didn't know that about heavy metal contamination... maybe your right... but how does boiling the water fix this problem, like when you make tea in the kettle or cook soup? Does boiling remove the heavy metals?
I'm sure you've heard of hepatitis? It is a virus that is comonly known to exist in contaminated drinking water.
I don't like making claims without evidence however so here are a bunch of websites you can read that show that yes virus's do exist in tap water.
Now you are right that virus's cant reproduce without existing inside a living host... however they can contaminate water and be preserved in their until drank.
Perhaps you have a point about the heavy metals being somewhat a problem, however considering that millions of Chinese drink boiled water every day, it would suggest that this new technology would be safe for use on the tap water if it does kill all the living organisms as claimed.
But if it's no better than boiled water, why use this new technology?
Because.... Boiling water takes lot of time and gas/electricity?
Try boiling water then taking a cold drink on a hot day...
How about water fountains? they almost don't exist in China... but they could with this technology...
Plus any technology that would encourage people to move away from the terrible impacts of bottled water is a huge deal.
We should embrace this technology... Technology is a good thing
Heavy metal and chlorine are what I'm really worrying about, so this UV won't do anything for me.
Well as someone who works in the relevant industry,for my own career 's good, i do hope this day will not come soon.
And back to the topic, UV ray is not enough to disinfect the water, add a RO system will do. and u can buy those things in the store even many years ago.
