Water Purification for Overlanding ?

[AA1PR]

not sure what area would be appropriate for this so here goes

 

[pugslyyy]

Well in my expedition rig I have a three stage - particulate then charcoal then UV. (so filter and sanitize)

Backpacking I will use iodine (old Army habits die hard) in emergencies.

Filter through a sawyer, and boil if you want the extra safety.

Water Purification Tests

Check out the Overland Journal (Fall 2009). They did a thorough evaluation of a few water purifiers. The tests included running several laboratory prepared samples, of varying degrees of contamination, of e-coli water through the filters. The water was then analyzed, post filtering, to see how much was removed by each filter. IMHO, very informative article.

I have an MSR filter, a sawyer squeeze, iodine tabs, aquamira, lifestraw, and a few other techniques.
My favorite is bringing enough water to drink from home, but that's not always possible.

We have been using a Big Berkey for the past 3 years and are very happy with the water. It filters out most biological hazards. The only drawback about this unit is that needs to be strapped down while traveling. It's great for base camping. I forgot to secure it several times just after I filled it and it tipped over. It's gravity fed and is top heavy until the water is filtered.

I usually clean the black carbon filters every few weeks to keep the flow fast.

Hi Gang,

Thought i'd resurrect this thread as the most appropriate place to question an purification method I just learned about: Puralytics SolarBag (http://puralytics.com/solarbag/).

This technology uses solar uv to run the process.

Further, the company has a powered (110 - 220v) led version for larger quantities. Not done any power analysis, but might be a candidate for vehicle powered water purification.

So, let the debate begin.............

It's an interesting product, but there are a lot of gaps in their sell sheets. How long does it take to purify, how many times can it purify, how do you know when it has worked, etc. How many times can I use one of their buzzword bingo bags before I have to discard it?

I've done pretty well with an inline system (particulate / charcoal / UV) at point of use, and in general am probably a bigger fan of on demand than batch processing for a camper.

If I'm hiking I'm fine with being able to dose found water a liter at a time and then drink half an hour later, but I remain a much bigger fan of the H2gO purifier than anything else I have seen.

pugslyyy: Actually, most of those questions are answered on their website (at least as far as solarbag is concerned since that is all I've read). Example: time to purify = 2.5 hrs (double in cloudy conditions), How to tell...die fades away, etc.

I bet most of your questions would be answered there.....

To get the usage info you have to go to another website (http://puralyticssolarbag.com) and drill down. There are also some good youtube videos and the review section on amazon is also pretty enlightening

How much do they charge for that clear plastic bag?
Because I can 30 of them for about $4.00

Kerensky97: amazon has em for $31.90

https://www.amazon.com/dp/B00OK5BDN...TF8&colid=1SKC02TL1BLAU&coliid=I3VL0BYOR449DN

Though be aware....i did see another amazon link pricing it at $400 (or thereabouts).

Let me know what technology and documentation the $4 solution yields.....

pugslyyy: Great contribution. I have been casually looking at purification for overlanders for awhile and not seen this! Just what this posting is all about....

Update: haven't dug deep, but see nothing but good reviews from the cloud (amazon, etc.).

Amazon @ $75 (https://www.amazon.com/dp/B00LOGHPU...lid=1SKC02TL1BLAU&coliid=I3F1NDNVG64CKO&psc=1)

Sorry about the web addresses....haven't figured the hyperlink method yet.

Been working fine for the past 3 years for my family.
We have the same matching setup for home backup also.

Just saw these today, way out of my budget; but an interesting product.

Wish there was more information, really expensive- I bet someone smarter than me could build one cheaper. Purification, in pelican case, w/ solar and battery.
