anyone use this type of product for water purification?

“PuripHy…is designed to raise the alkalinity of your water. ….This is achieved as puripHy optimizes the water by decreasing hydrogen ions and increasing hydroxyl ions.”

Snake oil, IMHO.

Do not use this for drinking water. It will do little to kill protists/bacteria etc. Basically, it will have around the same order of effect as Nacl or plain old table salt. In high enough concentrations, salt will kill bacteria, but you end up thirstier than you started. About the same here. What is the recommended dosage and is it recommended by the FDA? Ph is just a measure of acidity/alkalinity.  It says nothing about the antibacteria/anti-protista properties.Even 100% pure water will kill bacteria (but not all) and protists (again, not all.) I do not doubt it kills some, but not to the level of drinking water.

Total scam.
Come in sucker.

If your water is too acidic (something I’ve never encountered during any hiking or travel other than a few toxic-waste sites), add a pinch of baking soda.

If you have too much stomach acid, take a cheap anti-acid tablet. If that’s often the case, see a doctor and discuss proton-pump inhibitor drugs (like Prilosec, now OTC).

Those are the only two things this product could actually do.

For anything else, and especially for disinfecting water, use other, EPA-approved methods.

Hi David

The latest research on proton-pumps is NOT encouraging. Bad news in the long term.

There may be a possibility this mixture could help water sterilisation when using electrical current. Not a backpacking application tho is it?

water sterilisation when using electrical current
Um … you plan to electrocute them?
Sorry – explanation needed. How?

Cheers

It’s swimming pool technology.

It used very high voltage passing though water to generate chlorine ions but I have seen the army use similar tech along with filtering to produce drinking water from all sorts of sources

I really don’t think it can be scaled down to use batteries or solar panels

Ah, OK. Electrolysis of salt (NaCl). The result tastes absolutely vile.

Cheers

It gets better if aerated and filtered which is what the water treatment trucks do

Swimming pools taste bad as much for all the other chemicals we have to add to them, I dislike the taste of Soda Ash myself and I swear I can taste it even at 1:100,000.

In my hot tub, there is an “ozonator” to split O2 with UV light (or corona discharge), with some of the O- ions recombining into ozone.  The ozone, by oxidizing stuff (various organic molecules off your body, bacteria, viruses, etc), reduces the need (and potentially some of the expense) of using chlorine or iodine.  There is either an air pump to move atmospheric air through the ozonator or a venturi so that water flow sucks air through it.  Here’s an example that draw 6 watts:

so it seems possible as a portable, battery-powered device but if you try to simplify UV making ozone so ozone can treat water, maybe you end up just using UV directly to zap the bugs, like a SteriPen does?
