what is oxygen scavenger meaning？

Oxygen scavenger in water treatment is a chemical used to remove dissolved oxygen from water, also called oxygen scavenger packets. Dissolved oxygen is common in water, but for some specific industrial processes and equipment, too much dissolved oxygen may cause corrosion and oxidation problems. Oxygen scavenger is a special chemical additive. Oxygen scavenger chemical is mainly used in industrial circulating water systems, boiler water systems and other occasions where dissolved oxygen needs to be removed. Oxygen scavenger water treatment may cause metal corrosion, microbial growth and oxidation reactions, affecting water quality and the normal operation of equipment. The following is a detailed introduction to water treatment deoxygenators:

O2 scavenger usage:

Choose the appropriate type of water scavenger chemical, and select it according to the water quality and system characteristics.

Follow the manufacturer's recommended dosage and usage to avoid overdose.

Regularly monitor the dissolved oxygen content in the water to ensure the deoxygenation effect.

Pay attention to the storage and operation safety of O2 scavenger chemical, and avoid contact with incompatible substances.

Oxygen scavenger principle:

1. Chemical reduction: Through chemical reactions, dissolved oxygen is converted into inactive compounds, thereby reducing the dissolved oxygen concentration in the water.

2. Complexation: By forming a stable complex, the contact between metal ions and dissolved oxygen is reduced, reducing the corrosion rate.

3. Physical adsorption: Through adsorption, the dissolved oxygen is fixed on the surface of the oxygen scavenger to reduce the dissolved oxygen content in the water.

4. Catalysis: Catalysts can accelerate the deoxygenation reaction and improve the deoxygenation efficiency.

Oxygen scavenger function:

1. Industrial circulating water system: prevent corrosion and microbial growth inside the system, and extend the service life of the equipment.

2. Oxygen scavenger in boiler: reduce corrosion of boiler water, improve thermal efficiency, and prevent boiler scaling.

3. Pure water preparation: remove dissolved oxygen during the preparation of pure water to ensure the stability and purity of water quality.

4. Chemical industry: in certain chemical reactions, prevent dissolved oxygen from participating in the reaction to ensure the stability of the reaction and the quality of the product.

Common oxygen scavenger types:

1. Reductive deoxidizers: such as sodium sulfite (Na2SO3), sodium bisulfite (NaHSO3), etc., which react with dissolved oxygen through reduction reaction to generate inactive compounds such as sodium sulfate.

2. Complex deoxidizers: such as EDTA (ethylenediaminetetraacetic acid), which can form stable complexes with metal ions in water, reduce the reaction between metal ions and dissolved oxygen, and thus reduce corrosion.

3. Adsorptive deoxidizers: such as activated carbon, which removes dissolved oxygen through physical adsorption.

4. Catalytic deoxidizers: Deoxidizers containing catalysts, such as catalysts containing metals such as manganese and copper, can accelerate the deoxidation reaction.

When using oxygen scavenger, you need to choose the right product according to the specific application scenario and water quality conditions, and strictly follow the manufacturer's instructions to ensure safety and efficiency.
