NSF-61 Certification: Poly Processing is NSF-61 certified for Sodium Permanganate Storage.
Liquid oxidants, like sodium permanganate, are important in water treatment and other industries and how these agents are stored is equally as important. Sodium permanganate presents certain storage challenges, like its propensity to stain surfaces which it contacts.
Let’s take a look at sodium permanganate, its many uses, and how you can build an effective storage system.
Sodium permanganate is a chemical oxidizer used to treat drinking water by removing contaminants such as iron, manganese, or arsenic, and destroying any other organics that are in the water.
Since it dissolves more readily in water and can be fed at high rates, sodium permanganate makes for an ideal solution for controlling taste or odor issues. It also works to deactivate harmful pathogens and viruses, although technically speaking it is not considered a disinfectant.
Because of the high solubility in water, sodium permanganate is also good for uses that require high concentrations of permanganate ion, like the etching of the plastic parts that make up a printed circuit board.
The dark purple solution is explosive when it comes into contact with sulfuric acid or peroxides and may react violently with readily oxidizable materials. It also may ignite wood and cloth and is corrosive to eyes on contact. It must be stored in a well-ventilated area and be kept away from heat and sunlight, which pairs well with the black tanks.
In order to effectively store sodium permanganate, Poly Processing suggests the use of a Vertical Tank with an IMFO fitting, that allows for a full-drain. In the event that there’s no containment available or a secondary containment is needed, we’ve designed the SAFE-Tank as a “tank-within-a-tank” option, eliminating the need for additional square footage for a secondary containment tank.
