Question:
I installed water treatment equipment. Potassium permagnate(KMnO4) is soluble in water , is an oxidizer that you use with a greensand filter to remove iron from water. The greensand is used in the filter to oxidize the iron in the water and cause it to become a solid (like rust flakes)) that is then removed by the filtration of the greensand as it acts like a sand filter also. You have to backwash the filter every so often with potassium permanganate and lots of clean water to keep it from getting depleted ,plugged and packed down. Every 3rd day or so , on a whole house filter with 3 -5 occupants given the severity of the iron problem. also used as a disinfectant ,decontamination of skin, medicine, manufacture of organic chemicals and air and water purification. I’ve never used it to purify(kill bacteria/remove impurities) other than to regenerate iron filters for water. Potassium permanganate reacts violently with glycerin or glyceryl but I’m not real sure, which or both. It’s a Dangerous fire risk. It is an oxidizer and that helps fires burn. USE SOME COMMON SENSE Potassium chloride(KC) is a salt replacement and can be used in water softeners in place of salt(sodium chloride), In either case a small amount of the salt/potassium used in a water softener remains after all the minerals are flushed. It’s ion exchange trades an ion of salt for the ion of calcium/lime … during the cleaning and the salt ions stay until the water is used and is replaced by more calcium/lime. Some people sold silver nitrate impregnated block carbon filters as purifiers, the silver is supposed to kill bacteria in the water. In olden days on ships and wagon trips they tossed a silver coin in the fresh water and claimed that extended the time the water was usable. Never done it so I don’t know but it probably doesn’t hurt the water! – Hide quoted text — Show quoted text – time for you to go back to chemestry class. potassium, yes. potassium permanginate, no.

I GUESS IF YOU MIXED IT IN WITH H20 AND WERE STANDING CLOSE, YOU WOULDN’T HAVE TO WORRY ABOUT WATER PURIFICATION ANYMORE. TIM

As you say, should last forever. 2== Have never used it in water purification, though, usually use Lugols solution. What concentration of potassium permanganate do you use?
I carry a small 35mm film can full, in my gear. but it thru the drug store, from Humco, in 1 lb plastic jars, finely ground, $14 here. A few grains (as in sand grains) turns the water a light pink and kills all lower life forms, a few more grains – medium pink is a good mouthwash for sore throats, a few more grains – dark pink is an excellent wound dressing. mix a teaspoon full with glycerine (pure or ’some hand lotions’ or auto anti-freeze) and it will ignite "like a flare" for fire starter. ben – Hide quoted text — Show quoted text -~ larryn

What concentration of potassium permanganate do you use? ~ larryn – Hide quoted text — Show quoted text – I rent a water filter for my well system thatn uses potassium permanganate. It is in series with my water softener, and looks much the same except for the brine tank on the water softener. There is a smaller but similar tank for the filter that contains potassium permanganate. The serviceman told me that there is filter media in the large tank. When I put it through the cleaning cycle, there is a backwash cycle for the filter, a cycle where the media is washed with the p.p. and another back wash cycle. The p.p. is only to wash the media, not actually used in the filtering itself.

Response:
Has anyone used potassium permangamate for water purification? What are it’s long-term effects? How does it make the water taste? How much should be used per quart of water?
