Sodium Chlorite 31%

Sodium Chlorite 31% Solution – Trusted Oxidising Agent for Industrial Use

Sodium Chlorite 31% is, frankly, one of those underrated chemicals that does a lot of the heavy lifting behind the scenes. It’s commonly used in water treatment—municipal and industrial—and if you’ve ever wondered how large-scale disinfection or odour control works, this is part of the answer. It’s also the go-to for generating chlorine dioxide on-site, which, in case you didn’t know, is a pretty powerful antimicrobial.

As one of the more established chemical suppliers in Perth, we make sure our Sodium Chlorite 31% meets high purity standards and is backed by dependable supply logistics. You know, the kind that actually shows up when it says it will.

So… What *Is* Sodium Chlorite?

Sodium Chlorite (NaClO₂) is a pale yellow—sometimes light green—liquid that dissolves very easily in water. Its main purpose? To generate chlorine dioxide at the point of use. That’s where the magic happens. It’s surprisingly stable too, especially under standard storage conditions, and works well in both low-temperature and high-pH environments.

Oh, and for the record, some folks refer to it as sodium chlorite solution or even chlorous acid, sodium salt. The names vary, but the use remains the same.

🧪 About the 31% Solution

Now, 31% might sound like an oddly specific concentration—but it’s no accident. It hits a sweet spot between strength and manageability. It’s one of the most widely used concentrations here in Australia, partly because it’s powerful enough for industrial applications but still practical to store and handle safely.

Where does it usually go? Here’s a quick list:

• Drinking water disinfection setups
• Wastewater treatment facilities
• Paper and textile bleaching plants
• Food sanitation processes (depending on approval)
• Medical/pharmaceutical sterilisation procedures

It’s mostly colourless, sometimes with a faint yellow tint, and carries a light chlorine-like scent. And once activated with acid, it reacts quickly to produce chlorine dioxide gas—potent stuff.

🏭 Industrial Applications – and a Few Surprises

Sodium Chlorite is a favourite in industries where on-site chlorine dioxide generation is essential. That’s because it works—simple as that. Even at low concentrations, it acts as a highly effective oxidising agent, and unlike some older disinfectants, it doesn’t leave behind nasty chlorinated byproducts.

Industries like pulp and paper manufacturing, meat and poultry processing, and municipal water treatment facilities use it regularly. They rely on it for:

• Biofilm elimination in systems (the stuff can really cling)
• Neutralising odours in sewer lines
• Disinfecting surfaces that come into contact with food
• Legionella control in cooling towers
