Water purification - quickest way?

[Tom89]

Hi is anyone able to tell me the quickest way to purify a 1l capacity water bottle eg chlorine tablets, iodine drops etc cheers

From collection to consumption?

Filtration is going to be the fastest with a really good filter, like a Life Saver bottle.

Boiling next, assuming you have a stove or fire ready to go.

Chemical processes take time to work and manufacturers will have stated times, but Katadyn Micropurs take 30 mins or longer if giardia is present.

There is also UV sterilisation (Steripen) but haven't used that technique so know next to nothing about it.

Also the difference methods have different "success" rates, most methods reduce the biological contaminants (bacteria etc) but don't guarantee their complete removal. Whereas boiling is 100% effective.

There was a leaflet with the latest Bushcraft Magazine on these filter bottles, which look like they should fit the bill (there's an Xmas 20% discount too, if you're quick - no connection etc, and I haven't tried them myself - yet!)

Just to add, some background that's worth reading: http://paulkirtley.co.uk/2011/water-purification-5-contaminants-you-need-to-know-about/

boiling won't remove toxins such as blue green algae, or insecticides/sheep dip. Easiest way is the nasa filters, maybe two linked together will give you a failsafe.

The LifeSaver filters (bottle and jerrycan respectively) filter down to 1nm, and will remove all the nasties from the water. The only water source you absolutely cannot use is salt water (such as the sea or salt water estuaries)
I picked mine up on eBay for £40 each (I have 5 of them, don't ask)

Actually nothing removes all contaminants - not even distillation. Lifesavers will remove some chemicals - but by no means all.

Sure, if you're filling it up from a vat of toxic waste... but that's what your nose is for. If you can't stomach the smell, chances are it's too full of s**t to even think about filtering.

osmosis is meant to remove it all, but I've never heard of anyone use them. The flocculants of proctor+gamble fame are also meant to be very very good but are complicated.

There is a system made in the USA that uses a syrup solution.. through a membrain, and that is meant to work.. but it does leave yuo with sweet water..

I cant remember the name tho.. it was just like a water blader type system

1. Lifesaver Bottle or Jerrycan is Number 1 of my kit.
2. Next is my Katadyn Pocket filter used in conjunctgion with Micropure MF1000

If needing to go super lightweight then it's a very fine cotton bag + Steripen Freedom (can be recharged with PowerTraveller via micro usb) and Micropure MF1000 again
AFAIAC, clean water is a 'must have'. Falling sick with all sorts of bugs and nasties when you are a looooooooong way from home wrecks all your plans -
Trust me, liquid explosive bowels when sitting on a Thumper or when in your sleeping bag with a stuck zipper is NO laughing matter !
Stay safe out there

Just to add, what are the life straw's like? Any good?

 

[Dannytsg]

Potassium permanganate crystals. drop a few in to turn the water a light pink colour and leave it for a minute or two. Then it's safe enough to consume.

Another advantage is that if you carry potassium permanganate and glycerine on you, you can also start fire with them and also use them for medicinal purposes.

I have an ex girlfriend I know would be very good at using one... but personally, too much effort for me!

If you enjoy sucking (and there's no way to say that without it sounding dirty) then you might just like the Life Straw.

Heres the osmosis one I was thinking about

Cheers guys, has anyone had any experience e with the put hydration water bottles, I'm assuming their similar to the lifesaver bottles that have been mentioned ?

The water 2 go bottles are really good. I've drunk some filthy water through them and it comes out looking, smelling and tasting great.

Wow, never even heard of the Lifesaver bottles! I thought filtration alone was not sufficient for removing the nasties but it seems things move on?

It seems like an almost perfect solution to safe water needs? Can these be filled with heavily sedimented water and still work?

I would like to see a pump version of these akin to the Katadyn filters so an accumulation of pure water could be had without using a chemical post treatment to get almost 100% safe water.

Yes, these will filter heavily sedimented water (and there's a sponge inside you can use to even reduce the sediment substantially). Obviously, the more sediment you introduce to the filter, the quicker it'll reach the end of its operational lifespan (which is either 4000 litres or 6000 litres dependent on which version of the bottle you have, to 10,000 litres or 20,000 litres dependent on the version of the Jerrycan you have)

The LifeSaver Bottles are a pump system. In fact, here's a video showing how they work and how to maintain them:

I use one of these

I do carry a millbank bag to filter heavily sedimented water first but I've never actually had to use it in conjunction with the squeeze. I think it has a million litre lifespan or something ridiculous like that.
