    P&G Purifier of Water
    is a powdered mixture that removes pathogenic micro-organisms and suspended matter, rendering previously contaminated water safe to drink.

    P&G Purifier of Water contains a chlorine disinfectant (calcium hypochlorite) for killing bacteria and an iron salt coagulant (ferric sulfate) for removing suspended matter, protozoa, and viruses. It also contains a buffer, clay and polymer to provide good coagulation and flocculation.

    P&G Purifier of Water is safe for long-term use by the entire family, including infants, and is considered an effective technology by the World Health Organization(WHO).

    P&G Purifier of Water’s application results in water quality that meets WHO guidelines. In field and laboratory studies, P&G Purifier of Water has been proven to eliminate disease-causing microorganisms and to remove virtually all suspended material.

    P & G Water Purifying powder comes in a 4 gram sachet labelled in English. Each sachet treats 10 litres of water. The sachets arrive from the manufacturing facility in cartons containing 20 strips of 12 sachets each. Each carton contains a total of 240 sachets. P & G Purifier of Water requires only a few simple tools that most target beneficiaries of disaster assistance should have at their disposal:

    • A pair of scissors or knife to open the sachet,
    • A spoon or other implement to stir the water,
    • A cloth fabric to filter the treated water, and
    • Two vessels (i.e. buckets) with volume capacity of 10 litres or more – the first to be used for the treatment process and the second to be used for storing the treated water.

    I use a buff or similar for 1st stage, steripen for 2nd stage .. These seem great for big groups .. Not so practical for solo hiking needs

    I'd suggest it's worth bearing in mind that if the World Health Organisation is approving this product for use in disaster-stricken areas, then it's going to be dealing with a wider range of waterborne pathogens than those possibly encountered on an upland UK hike. In other word(s), overkill.

    I looked at this type of treatment a few years ago, but couldn't source any to try. TBH. I'd forgotten about them.

    Whilst I can see them being useful, I wonder what the discarded flocculant will do to the upland soils?
    I also wonder if the flocculant fraction will remove the Chlorine from the water, thus making them better tasting than trad chlorine tabs?

    There are times when upland water is a bit dodgy (usually around a Gixer meet), when the available water is either in spate and full of suspended filter blocking particles. There is usually a handy Froggy Doggy Boggy summer tarn handy to get water from and save shipping it up a mountain. I usually do 5l per 24 hours, that's half a sachet and 2g for nice clean water from a disgusting puddle that would make a Sawyer groan.

    Maybe the cotton could be replaced by a smaller washable and reusable stainless mesh?

    I may ponder these questions further on a hillside, while drinking Froggy Doggy tarn water coffee with a hint of dead Sheep/Deer/hikers turd. :hungry:

    My filter was buried in my bag last trip :sorry: we did carry 3 liters up (forgetting about the little tarn on the summit) but the day after I drank a load of "froggy doggy tarn water with a hint of dead sheep/hiker's turd (and pee)"....
    I survived :cool: and no dicky stomach, but really should filter it next time.

    Ladies tights should make a good particle filter.
