What is the tank marked potassium permanganate in the water treatment system for?
Friday, June 22, 2018
Potassium permanganate is an extremely strong oxidant used in water treatment to remove iron and the “rotten egg” smell caused by hydrogen sulfide, in conjunction with a greensand filter. It works by oxidizing the dissolved iron and hydrogen sulfide, along with manganese, into solid particles that can then be filtered out of the water.
We typically see this type of water treatment system at wells near a lake or river. The chemical is also referred to as “pot perm” and the top of the tank in a home system, like the one shown above, will have a warning about potential skin burns from direct contact with the chemical.
