What is Potassium permanganate?


Potassium permanganate is an inorganic compound. It is a purplish-black crystalline salt.

Potassium permanganate is widely used in chemical industry and laboratories as a strong oxidizing agent, and also as a medication for dermatitis, for cleaning wounds, and general disinfection.

Potassium Permanganate can be used as an oxidizing agent for disinfection on hatcheries and aquaculture facilities.  It is also used as a water treatment additive to react with organic matter in a pond such as algae, bacteria, and some parasites.




Is Potassium permanganate harmful to body?


Ingestion of potassium permanganate may result in damage to the upper gastrointestinal tract. Also it may cause systemic toxic effects such as adult respiratory distress syndrome, coagulopathy, hepatic-renal failure, pancreatitis and even death in severe cases. The systemic toxicity is believed to be due to oxidative injury. Manifestations of the gastrointestinal symptoms of potassium permanganate include nausea and vomiting. Ingestion of potassium permanganate can cause gastrointestinal complications too, similar to acid and alkali ingestion. Effect of potassium permanganate on the gastrointestinal tract is alkaline. Burns and ulceration of the mouth, esophagus and stomach are due to the action of potassium permanganate.

What does Potassium permanganate do to the skin?


Potassium permanganate can cause skin irritation, redness, pain, burns and skin hardening on contact with the dry crystals or concentrated solutions . Staining of skin can be experienced even with dilute solutions.



What does Potassium permanganate do to the eyes?

Inadvertent exposure of the eye to dry crystals (including crystal dust) or concentrated solutions can cause irritation, blurred vision, redness, staining of the conjunctiva, swelling of the eyelids and local burning.



Can we drink water with Potassium permanganate?


Potassium permanganate can be used in drinking water in the prescribed quantity. It acts as a disinfectant and helps to remove harmful bacteria and germs. Potassium permanganate when added in excess may cause ill effects on health.



How to Use Potassium Permanganate in Water Treatment?


Step 1

Determine the water's temperature, pH, and manganese and iron levels with a water sample test. You can tell if the levels of manganese are high visually, as the water will have a pink tint. The potassium permanganate dose needed for oxidation is 0.94mg per milligram of iron and 1.92mg per milligram of manganese. Rates of oxidatio will depend on the pH. Iron oxidation can occur within 10 minutes if the pH is 7.2 or more, but can require an hour if the pH is 6.9, according to the University of lowa.Manganese oxidation will be slower. It requires less than one hour only atapH of 9.5 or above. You may need a detention tank to give adequate time for iron and manganese to oxidize. If you are treating taste and odor, use doses of potassium permanganate ranging from 0.25 to 20mg per liter according to the manufacturer's instructions.

 

Step 2

Purchase pre-made tablets of potassium permanganate if you do not want to do your own calculations. Follow the manufacturer's instructions. For example, one product advises using one tablet per 50 gallons of water, but dropping back to one tablet per 100 gallons if you just want to improve water clarity, such as in a pond. Themanufacturer advises using two tablets per 50 gallons of water to treat bacterial and parasite problems. Tablets are sometimes found at garden and camping supply stores, as well as online (see Resources below).

Step 3

Filter drinking water to remove the manganese dioxide as well as the elemental sulfur precipitate that resulted from the treatment with the potassium permanganate. Potassium permanganate treatment is commonly paired with a "greensand" resin bed system. It's best to have your filter professionally installed, advises The American Ground Water Trust, because water quality problems often do not have straightforward solutions. Also get a written contract from the installer, the Trust advises.

Step 4

Store your potassium permanganate in a cool, dry area, advises the Carus Corporation. Keep it in a closed container. Also ensure it does not come into contact with peroxides or acids. Any combustible organic or readily-oxidizable materials should also be kept apart from the substance because it will support combustion, according to Carus.



What is the chemical treatment technology of Potassium permanganate?

In Industrial Water Treatment Process Technology,Potassium permanganate (KMnO4), used either alone or in combination with other chemicals, is effective in removing iron and manganese and oxidizing organic and inorganic materials that cause taste and odor. Dosages of KMnO4 vary from 0.5 to 15 mg/L, although dosages in

the range of 0.5--2.5 mg/L are usually adequate to oxidize most taste-and-odor-producing chemicals.



How potassium permanganate works?

Potassium permanganate is available as a dry, purplish solid. A device injects a solution of potassium permanganate into the water between the water pump and holding tank.

Potassium permanganate oxidizes iron, manganese, and hydrogen sulfide into particles. The particles are then filtered with a multimedia filter which can be either manganese-coated aluminum silicate above manganese-treated green sand or an 8-inch layer of anthracite above manganese-treated greensand. If an insufficient amount of iron, manganese, or hydrogen sulfide is oxidized prior to filtration, the manganese coating on the filter media acts as a backup oxidant to treat any remaining contaminant. If too much potassium permanganate is fed into the water prior to filtration, the excess potassium permanganate serves as a regenerant for the filter media.

The water should be colorless when it leaves the filter. When treating water to remove iron bacteria, a solution of potassium permanganate is fed into the well. A concentration of 3.8 to 7.6 grams per gallon has been found to be very effective. After the solution is added in the well, continuous agitation will help loosen and disintegrate sediment and organic material produced by the bacteria, thus enhancing treatment effectiveness. Agitation can be accomplished by turning the well on and off, which brings water up through the well casing and then lets it fall back into the well.
