Potassium permanganate is a strong oxidizing substance which is used to control taste, odor and removing manganese extensively. potassium permanganate is a weak disinfectant thus, it requires more time and density to disinfect water (e.g 2 mg/lit and 2 h) Potassium permanganate is a jade crystal salt that change into violet one when adding into water while detectable with naked eyes.

1. Municipal water treatment:

Removes iron, manganese, and hydrogen sulfide; eliminates taste, odor, and color; and controls algae growth. Growing applications for potassium permanganate are as a substitute for prechlorination to prevent the formation of trihalomethane (“THM”), a possible carcinogen, and as an inhibitor of zebra mussel attachment.

2. Wastewater treatment:

(a) Municipal–oxidizes organic and inorganic contaminants, removes toxic and corrosive hydrogen sulfide from sanitary sludge, deodorizes wastewater streams,and dewaters sludge; and

(b) Industrial–removes soluble iron and manganese from acid mine wastes, removes hydrogen sulfide from sludge, and dewaters sludge; controls phenol and otherindustrial pollutants.

Advantages of using potassium permanganate for disinfection are as follow:

1-     Easily detectable because of violet color

2-    Easily transportation and movement because of solid nature

3-    Lower risk of  the substance`s over-injection
