Sodium Chlorite 31%

Sodium Chlorite 31% – Reliable Water Treatment Chemical

Sodium Chlorite 31% is a clear or slightly yellow liquid used for water treatment, disinfection, and industrial bleaching. It’s common in Australia for making chlorine dioxide, which is useful in water plants, food processing, and the pulp and paper industry.

It helps remove harmful germs, keeps odours under control, and supports clean production environments. Since it’s a stable liquid, it’s easier to handle than chlorine gas.

What Is Sodium Chlorite 31%?

Sodium Chlorite 31% is made by reacting sodium chlorate with certain reducing agents. It contains 31% active sodium chlorite by weight. The main reason people use it is to produce chlorine dioxide when needed. This cuts down on risks because there’s no need to store chlorine gas.

It’s available in bulk, meets Australian water treatment standards, and comes with full traceability.

Where It’s Used and Why It Helps

Sodium Chlorite 31% is used in many industries because it’s reliable:

• In water plants, it’s used to make chlorine dioxide for disinfecting drinking water.

• In food factories, it keeps equipment clean and helps lower contamination.

• In paper mills, it’s used for bleaching without making as many harmful by-products.

• In wastewater plants, it helps with odour control and treating industrial waste.

It’s more stable than other oxidisers, releases chlorine dioxide in a controlled way, and reduces unwanted reactions.
