Ammonium Bisulphite – 40%

Ammonium Bisulphite – 40% is a lower-concentration solution commonly used in water treatment, paper bleaching, and food preservation (in some cases). It serves as an efficient oxygen scavenger and is ideal for applications that require reduced reactivity or milder chemical action.

Ammonium Bisulphite – 40% – Reliable Oxygen Scavenger for Industrial Water Systems

Ammonium Bisulphite – 40% is a widely used oxygen scavenger chemical engineered for safe, efficient removal of dissolved oxygen in industrial processes. Its 40% concentration makes it ideal for moderate-duty corrosion control, particularly in boiler feedwater treatment and oil & gas operations.

This stable, pale yellow solution is trusted across Australian industries to protect pipelines, heat exchangers, and storage tanks from oxygen-related corrosion. As a cost-effective and effective corrosion inhibitor, it ensures operational safety and equipment longevity.

What Is Ammonium Bisulphite – 40%?

Ammonium Bisulphite – 40% is a liquid blend of ammonia and sulphur dioxide, producing the active chemical NH₄HSO₃. This 40% concentration is carefully formulated to balance performance and safety. In the US, the term is often spelled as ammonium bisulfite (US spelling).

This solution is commonly used in closed-loop systems, where removing dissolved oxygen is vital to prevent pitting, scaling, and oxidation damage. The 40% grade is suitable for systems that don’t require highly reactive scavengers, offering dependable performance across applications.

Key Industrial Applications

Ammonium Bisulphite – 40% is used extensively in:

Boiler feedwater treatment to eliminate oxygen that causes corrosion and scale formation in boiler tubes.
As a corrosion inhibitor in cooling systems, pipelines, and oilfield water injection processes.
Food-grade processes such as caramel colour production, where controlled reactivity is required.

When comparing sulphite vs bisulphite solutions, the bisulphite variant is generally preferred for water-based systems due to its higher solubility and effectiveness at lower pH levels.
